Urban infill is driving taller, more condensed buildings to make use of the available space in cities. Suburban communities continue to push outward to take advantage of fringe territories. Plus, homeowners embracing a minimalist lifestyle are forgoing square footage for compact dwellings as part of the “tiny home movement.” Homes and buildings themselves look different as they adapt to meet the evolving needs of residents and businesses alike. It’s an exciting time for all facets of the building industry as we stretch our thinking, expectations and resources to build smarter in this time of change. In this issue of Engineered Wood, you’ll read in the cover story (“Meeting Code, Exceeding Expectations,” page 11) how the building industry is responding to fire codes with wood. Yes, it may seem counterintuitive, but advances in the engineered wood industry are allowing architects, engineers, codes officials and builders to produce creatively designed, structurally sound and code-adherent structures. As engineered wood is establishing itself as a cost-effective replacement for traditional fire-resistant materials in fire-rated assemblies, it’s also helping wood-framed buildings reach new heights and meet new goals. Mass Timber building practices—using products like laminated strand lumber and laminated veneer lumber—are helping architects around the world build tall, wood-framed buildings. In “Tall Wood Has Sky-High Capabilities” (page 05), you can read how Canadian architect Michael Green has set his sights on designing a Mass Timber Building 35 stories high. Others, like engineering firm Vertika Structural Engineers, are turning to Mass Timber members for the added strength it can provide. Looking to put a bowling alley on the second story of a building or hang a jet plane from the ceiling? Then be sure to read how Vertika made this possible with Mass Timber in “LSL & Steel Deliver Strength & Stability” on page 04. Continue reading this issue of Engineered Wood for these stories and more so you can stay up to date on the news, technology and tools affecting the building industry.

The product is comprised of all traditional materials, and it was created to effectively withstand natural elements. Sage glass blocks the sun’s harsh rays during summer and secures heat inside during the winter. According to the manufacturer the smart glass is coated with metallic oxide, and it is proven to significantly bring down HVAC costs. Using minimal electricity, the smart glass charges ions to control the amount of light it reflects. Thus, the glass tints during the sun’s peak hours, returning to transparent at night. + • Installs like traditional lumber, but surpasses in strength and consistency • Provides uniform dimensions and straight, long lengths • Consistent low moisture content helps resist twisting, warping and shrinking • Wood sourced through programs certified under the Sustainable Forestry Initiative® Zeeland sought a product that would: • Allow for easy installation • Provide a strong, durable foundation SOLUTION Zeeland selected LP® SolidStart® LSL for the interior wall frames. “Since the facility is externally solid steel, we needed a strong product with long-length availability to support the 20-foot-high ceilings on the interior,” explained Mike Dykstra, CEO of Zeeland Lumber & Supply. Dykstra, who has over 20 years of industry experience, found that LP SolidStart LSL was easy to install thanks to its uniform dimensions and straight edges. The EMGLO® Air Force Power Stacked Air Compressor is a compact, four-gallon stacked-tank compressor. According to the manufacturer, it is equipped with enough power to simultaneously run four pneumatic trim nailers, two framing nailers, two roofing nailers, or two flooring nailers. The EMGLO unit comes with a twowheel dolly and extendable handle, making it easily transportable through the messiest construction sites and even up and down stairs. It features an oil-lubricated pump with cast-iron cylinders, 125 maximum air-pressure output, and dual soft-start valves for fast and easy start-up in cold weather. OUTCOME The new state-of-the-art truss manufacturing facility is on track for completion later this year. “This facility wouldn’t have been possible without the strong foundation that SolidStart LSL provided,” said Dykstra. “We have had a valuable relationship with LP for nearly ten years thanks to their reliable service and consistent, quality products.” ■ Courtesy: Emglo * This information and the websites identified above are provided solely as a convenience to the reader.

ENGINEERED WOOD 03 L S L I N M A S S T I M B E R CO N S T R U C T I O N LSL & STEEL DELIVER STRENGTH & STABILITY Over the past several years, wood has become a viable choice for taller projects that typically require the strength of steel or other similar products. This trend—known as Mass Timber—is based around the use of large prefabricated wood members such as laminated strand lumber (LSL), laminated veneer lumber (LVL) or crosslaminated timber (CLT) for wall, floor and roof construction. Mass Timber supports an accelerated construction process, but it’s also expanding the possibilities of wood construction. A 33,000 sq. ft., two-story multiuse facility near Houston recently incorporated LSL products into Mass Timber members, marking one of the first uses of LSL in this application. “BECAUSE OF THE NEED TO ACHIEVE A SIGNIFICANT AMOUNT OF STRENGTH WHILE STILL BEING ECONOMICAL, I THOUGHT A HYBRID OF STRUCTURAL STEEL AND MASS TIMBER WOULD BE THE BEST SOLUTION.” 04 WINTER 2016 Vertika Structural Engineers, LLC worked with BIGenterprise using wall and floor panels made of LP® SolidStart® LSL. Engineer Thomas Bellace, Principal for Vertika, designed the unique structural system. “The owner asked me to create a design for a structural system for this building. Because of the need to achieve a significant amount of strength while still being economical, I thought a hybrid of structural steel and Mass Timber would be the best solution,” Bellace said. “After working on some projects with LP SolidStart LSL, I knew that was the product I needed—both because of its strength and the support I trusted my LP sales rep to provide.” Bellace had a prefabricator create 7-inch-thick LSL panels, using Dowel screws and two 3.5-inchthick LSL panels, which were then secured on-site using steel connections. The strength and thickness of the LSL panels helped with both noise control and fire resistance, and combined with LSL reinforcing strips provided a stiff floor with almost no perceptible bounce, even on the second story intended for a dance floor and a bowling alley. The structure also has a garage, apartment, commercial kitchen, flight simulator and an elevator, all wrapped by a veranda. “We did our own unofficial test of the stiffness of the floor by having eight of the workers—all 250 pound men— jumping up and down,” Bellace said. “It felt like you were jumping on a concrete floor.” The building also has tall ceilings from which the owner planned to hang a jet. Bellace designed the main roof joists, beams and spandrels with LSL combined with massive steel ridge frames to provide the necessary additional strength. The build took nearly two years since it was both a unique design and Bellace’s first foray into Mass Timber, but he doesn’t expect it to be his last. “Since completing the building, I’ve been innovating more ways to use the technology in other projects here in Houston, including plans for some multi-story wood structures,” said Bellace. ■ WOODEN “SK YSCR APERS” ARE GAINING POPULARIT Y AROUND THE WORLD Tall Wood Has Sky-High Possibilities Thanks to the engineering strengths of Mass Timber products—including those made with laminated strand lumber (LSL), laminated veneer lumber (LVL) and cross-laminated timber (CLT)—tall wood-framed structures (sometimes referred to as “plyscrapers”) are beginning to accent skylines throughout the world. According to The Economist, Tall Wood buildings use about six times as much wood as a structure made with conventional techniques. Builders just completed construction of the world’s tallest wood structure, known as “The Tree”—a 14-story, 160-foot-tall apartment building in Bergen, Norway. The structure of The Tree is made of wooden columns in a stacked modular system. A facade of glass and metal will enclose the structure once all modules are in place to protect it from the wet climate of Bergen. Canadian architect Michael Green, considered the “father of the Tall Wood movement,” is planning a 35-story wood tower as part of the “Reinvent Paris” initiative in the French capital. Green recently told CNN that “just as the Eiffel Tower redefined the skylines of the world, our wood tower in Paris will help champion a new global wave of building with more sustainable, renewable and beautiful materials.” Tall wood-framed towers have a bright future, according to the architectural firm Skidmore, Owings & Merrill (which built both the Freedom Tower in New York and the Burj Khalifa in Dubai, the world’s tallest building). In a 2014 study, the firm noted that a 38-story wood skyscraper was technically possible—and that it would be economically competitive with conventional construction while also cutting the carbon footprint by as much as 75 percent. This night shot of the Wood Innovation Design Center in Prince George, British Columbia reveals Tall Wood’s stunning beauty. We won’t be seeing any extremely Tall Wood towers in the United States in the near future. The current limit is five stories for residential and six stories for office buildings. Though not as tall as our international counterparts, U.S. Tall Wood structures create many domestic opportunities for LP products. Because LP® SolidStart® LVL and LSL are less susceptible to moisture changes and shrinkage, they’re being used to help reduce plate shrinkage in tall (heavy timber) construction. Despite pushback from concrete and steel trade groups, the Tall Wood movement has a lot of momentum in the United States. Many architects and builders are convinced that soaring wood towers will soon be a reality—not just a tall tale. ■ Photo by Ema Peter courtesy of Michael Green Architecture ENGINEERED WOOD 05 B U I L D I N G TO M E E T H O M E B U Y E R N E E D S According to a 2014 survey of 500 residential architect firms by the American Institute of Architects, nearly 39 percent of respondents said they are seeing increased demand for floor plans with an in-law suite (for example, a secondary master bedroom with full bathroom) or dedicated guest room. This was an increase of 26 percent and 10 percent who cited the same in 2013 and 2012, respectively. The Evolution of the Floor Plan While a master bedroom seems second nature to many Americans, the trend only began in the mid-1980s during the rise of the “McMansion.” Many of today’s homes include the much larger master suite, complete with a larger closet and full bathroom. But while many Americans have become accustomed to a floor plan with a traditional master bedroom, a new trend in floor plans has begun in which a second suite—nearly comparable to the master suite—is included. This new movement can be attributed to certain economical, generational lifestyle and physical influences occurring recently in the United States. Take Millennials, for example. Compared to their parents’ and grandparents’ generations, Millennials are, on average, waiting until later in life to start a family and buy a house in which to settle down. On the economic front, the cards seem somewhat stacked against Millennials. They are faced with more student loan debt, incomes that don’t match the rising cost of a home, and skyrocketing rental costs. What is the solution for Millennials entering the housing market? Stay at home with Mom and Dad. According to a July 2015 report by the Pew Research Center comparing U.S. Census Bureau data from 2010 to 2015, more young adults are living at home now than five years ago—despite a rebounding economy and decreasing unemployment rate among young adults in the United States. 06 WINTER 2016 Another factor is attitude, be it positive or negative. Many Millennials are choosing to stay under their parents’ roofs longer as a way to pay off student loans or to save for big “adult” moments, like buying a car, paying for a wedding, or putting a large down payment on a house. Admittedly, this is not the case for all Millennials, with some opting to stay at home longer not for the financial footing it provides, but out of convenience. On the other end of the spectrum, Americans are living longer. The average life expectancy continues to increase, and most Americans are expected to live, on average, to nearly 79 years old. To avoid the cost of an assisted living center and to provide in-home care longer, many Baby Boomers are cohabitating with their own aging parents even more frequently. Additionally, retirement finances may start to dwindle due to extended lifespans, new healthcare concerns and inflation. The concept of “aging in place” has picked up steam as more adults prefer to age at home as long as possible, which often means relying on in-home caretakers. This also means custom-built or remodeled homes to accommodate an aging homeowner over time. The housing industry has taken notice of these trends in cohabitation between generations, and industry professionals are adjusting accordingly. “As many households become caretakers for aging relatives, separate living suites have become popular options for accommodations,” said Kermit Baker, chief economist for the AIA, in a news release. Williams Custom Art Builders has a project under development in the Chatham Hills community near Indianapolis. Chatham Hills includes a section specifically for empty nesters. The Williams project is a custom home with in-law quarters on the main level in addition to the master bedroom. Though the master is larger, the in-law quarters are very large as well. The in-law quarters in a Williams home often include features like zero-threshold showers to eliminate the step up when entering and exiting as well as threefoot-wide doorframes to accommodate a wheelchair or walker. Likewise, CBH Homes is addressing the “aging in place” concept and multigenerational living in its Idaho developments. Corey Barton, CEO and president of CBH Homes, explained, “We created this new floor plan, Dwellinghood, to give buyers flexibility with their home as life stages evolve. Whether you have adult children, in-laws or even for a renter, the Dwellinghood option allows everyone to have their own space, yet still be close together should they choose.” Said Barton, “Incorporating flexibility into the plan designs along with the latest trends will benefit resale and allow future consumers to live in their home the way they desire.” ■ For Steve Williams, of Williams Custom Art Builders, building houses in this style is not totally new. “We’ve been hearing this for a couple of years. A lot of people are talking about one of their elderly family members moving in with them.” Williams continued, “It is important to have both main bedrooms on the main level of the house or to include an elevator.” For some projects, the elevator shaft is put in place during initial construction, but it is used as closet space until the resident requires the actual elevator be built into the shaft space. As a current LP Building Products user, Williams Custom Art Builders will be incorporating a number of LP materials into the Chatham Hills projects, including LP® TopNotch® Sub-Flooring; LP® SolidStart® LSL and LVL; and LP® SmartSide® fascia and soffit. Zero-clearance thresholds, wider doorframes and elevators are, according to Williams, going to eventually become the norm for houses built for aging in place. “In this type of home, it’s going to become a thing like all houses now having nine- or ten-foot ceilings,” Williams explained, comparing it to the trend in rising ceilings. “It is going to become standard because there are so many aging people.” ENGINEERED WOOD 07 D O W N S IZI N G Tiny Homes, Big Opportunities The tiny house movement began to attract attention when the financial crisis hit in the late 2000s, with more people trading space for a simpler, more affordable lifestyle. Still growing in popularity today, tiny homes are less than 400 sq. ft. and typically cost between $20,000 and $50,000. Living in them takes a radical shift in mindset—and so does building them. First, you’ve got to be able to offer the homeowner options. That means knowing what materials are appropriate for a tiny home. “One of the things to understand about a tiny house is that it is a glorified shed that has been converted into a custom, nice, small house,” says Andrew Odom, Founder of Tiny r(E)volution. Odom has been writing about the trend since he built his own tiny home six years ago. His relationship with LP Building Products began in 2009 when he called asking for guidance about what products would work best for his needs. As the trend for tiny homes increases, more homebuyers are downsizing as a way to live simply, more affordably and with fewer possessions. To build a tiny house that meets the needs and wants of buyers, building professionals should approach each project with both a creative and practical lens. Consider that to build a tiny home is, essentially, to reduce a whole house to the size of someone’s master bedroom. “It’s perfect siding for a structure that’s small. I wouldn’t use this on a 2,800 sq. ft. house without sheathing underneath, but for a tiny house—a cottage, cabin, shed, or small house on wheels— I wouldn’t hesitate,” says Odom. What initially drew him to the product was the natural looking texture and the natural look of real wood lap siding. LP SmartSide Trim & Siding comes in a variety of finishes, including trim and fascia, cedar shakes, lap, soffit and panel. According to Odom, “Because it’s such a tight composite it’s just a smooth cut all the way down, so all you need is a table saw. And all of the finishes are pre-primed so the painting process is faster and less expensive.” The product and the process both worked. “We rode out two major storms on the East Coast with no damage whatsoever to the siding,” says Odom.■ Odom didn’t want to go the traditional sticks and bricks method of using a sheathing coat, sheathing layer, and then adding siding. He chose LP® SmartSide® Trim & Siding because it can be used as an exterior for tiny homes without sheathing underneath it. LP Building Products provided LP® ProStruct® Flooring with SmartFinish®, LP® ProStruct® Roofing with SilverTech®, and LP® SmartSide® Panel with SilverTech® in-kind to Andrew Odom for use in his tiny home. One of the things to understand about a tiny house is that it is a glorified shed that has been converted into a custom, nice, small house. FUN TINY HOUSE ILLUSTRATION GOES HERE From choosing the right materials to taking advantage of smaller crews and faster dry-in times, building a tiny house is different than building a home of traditional size. But it’s still possible for building industry professionals to find big success in the smaller-sized market.

BUILDER NEWS & TRENDS 1 LP® TechShield® used in LEED “House of the Year” This year, the U.S. Green Building Council’s (USGBC) outstanding single-family LEED home of the year featured LP® TechShield® Radiant Barrier Sheathing. The four bedroom, three-and-a-half bath, 3,400 sq. ft. house is in Kailua, Hawaii, and is the first in the state to be certified under the latest version of the LEED for Homes program. The builder, Mokulua High Performance Builder, emphasized the need for a radiant barrier in the home’s design, given the region’s warm climate and abundant UV radiation. LP TechShield sheathing was selected as the roofing solution for the sustainable home. LP TechShield is America’s original and #1 radiant barrier sheathing, able to reduce monthly cooling costs by blocking up to 97% of the radiant heat in the panel from emitting into a home’s attic. 10 WINTER 2016 NO. NO. 2 Let the outdoors in … and take the indoors out For practical climates, an indoor/ outdoor living space can be a unique way to blend your house with the beauty of its surrounding nature. Whether it’s an open-air courtyard or a living room with large sliding glass doors to let the outdoors in, spaces that open to nature bring a serenity that is hard to capture with indoor plants. An outdoor facing fireplace can bring the coziness of a living room outside to a comfortably furnished patio for the perfect indoor/outdoor effect. Even fully covered kitchens are making a move outdoors so chefs can entertain guests outdoors while cooking up a summer meal. According to realtors, many homebuyers are seeking properties with outdoor living features. 3 AIA accepts the 2030 Challenge In 2002, a nonprofit think tank called Architecture 2030 began with a mission to “rapidly transform the built environment from the major contributor of greenhouse gas (GHG) emissions to a central part of the solution to the climate crisis.” Thus came the 2030 Challenge that all new buildings, developments and major renovations shall be carbonneutral by 2030. In response to this challenge, the American Institute of Architects (AIA) formed the AIA 2030 Commitment to help architects meet the energy efficiency and emission reduction goals of the 2030 Challenge. The AIA’s national initiative provides firms with a standardized reporting system to help evaluate the impact that design decisions have on a project’s energy performance. Architects are encouraged to take AIAU courses on the 2030 Commitment to help architects create the next generation of energy-efficient buildings. ■ MEETING CODE, EXCEEDING EXPECTATIONS ENGINEERED WOOD INNOVATIONS ARE HELPING DESIGNERS AND BUILDERS MEET EVOLVING FIRE CODES WHEN THE GREAT FIRE OF ROME OCCURRED during Nero’s reign, the results led to the world’s first fire code. This code in 64 A.D. banned common walls except those made of fire-resistant materials. In America, building codes date back to the Jamestown colony in Virginia in the 1600s, and the first actual fire code was recorded in 1631 when Boston outlawed thatched roofs. As communities, architectural styles, materials and populations evolved, so have codes. ENGINEERED WOOD 11 F I R E CO D E S A CLOSER LOOK AT CODES Fast forward to today, where many skylines are dotted with rising multifamily housing developments and new infill construction is burgeoning. This change has a direct impact on the evolution of building codes. In a 2015 report by the Federal Emergency Management Agency (FEMA) on “Multifamily Residential Building Fires (2011–2013),” multifamily residential building fires accounted for an annual estimated 106,000 reported fires. This is equivalent to 28 percent of all residential fires responded to by fire departments across the United States. On average, the multifamily residential fires resulted in nearly 400 deaths, around 4,250 injuries, and $1.3 billion in property loss annually. The good news, however, is that fire fatalities and injuries have declined over the past 35 years. In addition to stricter fire codes, the increased presence of smoke alarms as well as the increased use of residential sprinkler systems contributed to the decline. But according to the FEMA report, smoke alarms were only present— though not necessarily working—in 62 percent of non-confined multifamily fires during the survey period. Within that 62 percent, the alarms failed to operate or the fire was too small to activate the alarm in 11 percent and another 12 percent of fires, respectively. In 1994 three building inspection agencies merged to form the International Code Council (ICC), and in 2000 the group introduced the first edition of its International Building Code (IBC). The IBC is a “model” code that provides guidelines for the structural requirements of buildings. Various jurisdictions (states, cities and fire districts) can then either adopt or amend the IBC model by enacting it into law. For example, Texas is still using IBC 2006 and Connecticut continues to use IBC 2003. A majority of U.S. states are now officially using IBC 2012, while South Dakota and Maryland have promptly enacted IBC 2015. Every three years the ICC revises its model codes, which include the IBC, the International Residential Code (IRC) and the International Fire Code (IFC). The IRC solely addresses one- and two-family dwellings that are three stories or less. “In an effort to help designers and builders, the IRC incorporates some of the provisions from ICC’s other model codes like the ones for fire and plumbing,” says LP EWP Application Engineer Reid Williams. “Texas has a decentralized system of building codes that allows local jurisdictions to adopt the 2006 code or more up-to-date editions,” says Si Farvardin, manager of codes and standards at the Insurance Institute of Business and Home Safety. “Many U.S. jurisdictions have also enacted the International Wildland Urban Interface (IWUI) code. Western states like Colorado and Utah have adopted it, plus a few eastern states like Georgia and Pennsylvania. These jurisdictions have the ability to modify and even exceed IBC code requirements. California’s wildland fire code is the most restrictive in the United States, and it predates the IWUI code.” New techniques and materials are continually emerging to help the building industry build fire-resistant structures that are code compliant, aesthetically appealing, and cost-effective. For nearly a century, designers and builders of wood-framed structures have been using gypsum to meet fire codes. Architects can now also look to engineered wood products that meet fire codes and provide greater strength, savings and design flexibility than either gypsum or fireretardant treated (FRT) plywood when used in certain assemblies in single-family, multifamily, and light commercial construction. As these building codes evolve, the demand for fire-resistant wood-based products will likely continue to grow across these building types. Buildings are classified into construction types numbered Category I through Category V, based on height, area, intended usage and occupancy. The International Building Code (IBC) requires fire-rated assemblies (exterior/interior walls and floors/ceilings) and materials within the building to meet various fire resistance and flame spread ratings based on construction type and other factors, such as fire separation distance (e.g., distance from property line). Materials have fire-resistance ratings, referring to the “ability of a material or an assembly to resist burn-through and, in load-bearing assemblies, to support a given load for a specified time period under standardized fire conditions,” per the IBC. Assemblies, on the other hand, have flame spread ratings that refer to the “measure of the speed of travel of flame on the surface of a given product or material under a standard set of conditions,” per the IBC. Fire resistance ratings specify the time duration for which an assembly must withstand a standard fire resistance test (typically one to four hours). 12 WINTER 2016 LP ® FL A M E B LO CK® EX TERIOR LOAD - BEARING WALL – I N TE R TE K LI S TI N G L P B / W P P S - 6 0 - 01 LP ® FL A M E B LO CK® EX TERIOR LOAD - BEARING WALL – U L D E S I G N NO. U349 ENGINEERED WOOD 13 F I R E CO D E S F I R E CO D E S CONFUSING PATCHWORK OF CODES On a local level, one of the most difficult aspects of code compliance is understanding the differences in the dozens of jurisdictional codes within a single metro area. “There are 90 municipalities and a large number of fire districts in St. Louis County, plus a different code for the City of St. Louis,” says Matt Belcher, a principal at Verdatek Solutions in Wildwood, Missouri. “There are so many jurisdictions that architects and builders frequently have to contact each district themselves to sort through the local requirements. On large commercial projects, they sometimes use a code consultant to help address overall code issues.” For some architects, the extra work is justified if it leads to more innovative designs, speedier construction, or reduced material/labor costs. “The better architects look for value-added opportunities throughout a project, including fire-rated wall design,” adds Belcher. “Other architects are content with the same-old, same-old. Staying educated about new technologies is what separates the first group from the latter.” ARCHITECT- FRIENDLY TECHNOLOGY Fire-resistant building materials from LP Building Products— LP® FlameBlock® Fire-Rated OSB and LP FlameBlock I-Joists— start with the proven strength of OSB panels. For LP FlameBlock Fire-Rated OSB Sheathing and LP FlameBlock I-Joists, a patented non-combustible Pyrotite® layer is added to the OSB panels. When exposed to extreme heat the Pyrotite layer releases moisture which slows the spread of heat and flames through or along the wall or roof. Technological advances, like LP FlameBlock sheathing and I-joists, continue to help the building industry reach new heights in fire resistance. “A building needs to be safe but also serviceable, delivering added value like greater fire resistance, moisture management and sound reduction,” says Dr. Richard Bennett, a University of Tennessee engineering professor who’s one of the world’s leading experts on building material trends. “Fire-resistant OSB products have many advantages over other materials because they can be engineered to meet changing performance criteria.” ■ 14 WINTER 2016 Value-Added Features in Fire-Rated Products STRUCTUR AL STRENGTH – OSB has design values for load/span and shear that are superior to FRT plywood at the same thickness. LP® FlameBlock® Fire-Rated OSB Sheathing assemblies reduce dead load and wall thickness versus common alternatives. DESIGN FLEXIBILIT Y – An OSB panel with fire-resistant coating carries load/span and shear design values equivalent to an untreated wood structural panel in the same thickness category. Using that combination in fire-rated wall assemblies can provide more flexibility in designing wall openings as well as more options in framing and bracing to meet structural requirements. MOISTURE MANAGEMENT – Some fire-resistant materials, like LP FlameBlock sheathing, are Exposure 1 rated, which means that they can withstand exposure to moisture during normal construction delays. SOUND REDUCTION – Today’s building code requires walls to have a Sound Transmission Class (STC) rating of 50. This includes partition walls between living units and exterior walls adjacent to walkways and alleys. Certain wall assemblies—including some using LP FlameBlock sheathing—can deliver up to a 61 rating depending on the configuration. Where Fire-Resistant Products Are Used Fire-resistant products are code-compliant components of 1-hour and 2-hour firerated wall assemblies, roof deck applications, and I-joist and LSL applications that need to meet the “Fire Protection of Floors” requirement in the IRC. EXTERIOR LOAD - BEARING WALLS – Fire-resistant panels are used in a variety of exterior load-bearing walls, including those designed to meet code for zero lot line and infill construction where a structure comes close to the property line. INTERIOR LOAD - BEARING WALLS – These are typically 2-hour fire-rated partition walls in multifamily construction. ROOF DECK APPLICATIONS – Fire-resistant panels are commonly used to provide vertical continuity of roof decks in townhomes, condos and apartments. Architects can choose products with 7/16˝ thickness to provide consistency with 7/16˝ standard OSB roof sheathing where desirable. Plywood is not available in that thickness. IRC- COMPLIANT I -JOIST AND LSL APPLICATIONS – Designers must now comply with 2012/2015 IRC provisions for the fire protection of floors while achieving the level of performance that homeowners have come to expect. ENGINEERED WOOD 15 I N E V E RY I SSU E MARKETING TIPS FOR BUILDING PROFESSIONALS “GREEN” TERMS TO USE AND AVOID First, you should stop using the word green. It’s not as descriptive as it once was and is often associated with greenwashing, which is when public relations or marketing is deceptively used to promote the perception that an organization’s products, aims or policies have environmental benefits. Consumers and buyers have noticed that organizations sometimes spend more time and money claiming to be “green” than actually implementing business practices that minimize environmental impacts. It’s important for building industry professionals to understand (and use) the various industry terms in circulation. SUSTAINABILIT Y Also known as sustainable harvesting, practicing sustainability means you meet the needs of the present without compromising the ability of future generations to meet their own needs. This is done by using an array of sound practices in the conservation of forests— including appropriate protection, growth, harvest and use of those forests—incorporating the best scientific information available. 16 WINTER 2016 At LP, we believe that sustainable forestry can be best accomplished when forest landowners, contractors and wood producers are informed and work together toward a similar goal. CERTIFIED WOOD Certified wood comes from forests that meet particular standards regarding responsible management practices. Independent thirdparty organizations develop the standards of good forest management, and independent auditors issue certificates to forest operators that comply with those standards. More than 50 certification programs exist worldwide, addressing all of the various types of forests. CHAIN - OF- CUSTODY Chain-of-custody is a tool used to track wood from the forest through the manufacturing process to the customer and consumer. This provides a clear link between certified forests and certified products. Through chain-of-custody, it’s possible to accurately identify the percent content from certified forests in each product. Just like certified wood, chain-of-custody is verified by an independent thirdparty audit. ■ + To read more about the sustainability initiatives of LP Building Products, visit LPCorp.com and click on the “Sustainability” tab. Dryvit TAFS 3 built on LP SmartSide Substrate ® ® The look of stucco has been a popular home exterior for decades. Today, LP Building Products and Dryvit have teamed up to offer that great look, utilizing new technologies which apply faster, perform better and save money. The LP® SmartSide® Substrate is a smooth, treated engineered wood strand panel that comes in 8-, 9- and 10-foot lengths. It is the structural panel for the house and replaces the normal OSB sheathing in the framing package. It works and cuts like wood, and it requires no special tools. Like all LP SmartSide products, the substrate is manufactured with the proprietary LP® SmartGuard® process to help prevent fungal decay and termite damage. It is applied over a code-approved weather barrier. Dryvit Textured Acrylic Finish System (TAFS) 3 is then applied to achieve the desired aesthetics. TAFS 3 includes joint treatment, primer and a textured, integrally colored acrylic finish used with the LP SmartSide substrate. With a range of textures and color options, TAFS 3 can be customized to meet the homeowner’s taste. While many of the textures replicate stucco, others are available to provide the realistic look of granite, limestone and even brick. This design flexibility allows builders to offer many other high-demand exterior finishes beyond stucco when using the TAFS 3 built on LP SmartSide Substrate system. The combination of LP SmartSide and Dryvit TAFS 3 is, in essence, a siding system with a proven and durable finish option, which together apply faster, look better, and offer more value than traditional three-coat stucco. From a building science and building codes perspective, that is a big advantage to both builders and their installers. This system is already used in Texas and will be introduced in other markets around the country throughout 2016. ■ + For more information, please contact LP segment marketing manager David Josey ([email protected]). ENGINEERED WOOD 17 SUS TA I N A B I L I T Y LP considers many factors both prior to and after harvest, not only for migratory birds but also for many plant and animal species that inhabit the lands we manage. We are committed to responsible forest stewardship and helping to ensure that forests are provided for generations to come. Migratory Bird Conservation is a Long-Term Journey BY DONNA KOPECKY Every year, millions of migratory birds leave locations in Central and South America to make the long journey north to return to their treasured nesting grounds in habitats across Canada and the Northern United States. forests with a variety of canopy openings that are littered with dead-standing, gnarly-looking trees. Still others prefer prime residential property adjacent to streams, rivers, lakes or wetlands. LP works to minimize its environmental footprint adjacent to sensitive ecosystems such as riparian areas for species that prefer to nest along streams, rivers, lakes and wetlands. From ducks and geese to warblers and hummingbirds, migratory birds travel great distances and overcome many obstacles in order to breed and grow in number. Birds are able to navigate back to breeding and wintering grounds using information from the stars, the sun, and the earth’s magnetic field. Many habitat combinations exist across forest landscapes that are suited just perfectly for different species of birds and bird communities as a whole. In areas where heron colonies or raptor nests are detected, LP often will protect them by avoiding activity during the birds’ nesting period or by applying a no-harvest zone to protect the site from operational activity over the long term. These operational practices and many others contribute to conservation efforts for migratory birds. For example, the hummingbird is the smallest bird species, but it can travel up to 2,000 miles to breeding grounds in the United States and Canada. Flying an average of 25–30 miles per hour, it can take a hummingbird about 20 hours to cross the Gulf of Mexico. With research showing that some migratory bird species numbers are declining, government scientists, conservation groups and the forest industry are working together to better understand factors in both summering and wintering locations that may be contributing to the decline. These collaborations aim to best manage habitats so that both birds and forests continue to thrive. Depending on the species, forest birds require specific habitats throughout their breeding and nesting cycle. Some prefer young regenerating forests with thick understory vegetation, while others prefer mature 18 WINTER 2016 Scientists and land managers agree that no single forest type or age class, nor any single forest management strategy or practice, will benefit all species. LP Building Products is working collaboratively with stakeholders to develop and implement planning and operational strategies to help ensure that a variety of habitats are maintained for birds throughout the forest areas LP manages. By implementing practices such as variable retention harvesting and snag retention, LP maintains residual forest structure within a harvest unit to provide habitats for a variety of bird species such as woodpeckers, raptors and songbirds. A woodpecker can peck 20 times per second and make 8,000–12,000 pecks per day to create tree cavities crucial to creating homes for many other species of forest birds, as well as other animals such as bats and pine marten. LP has also established partnerships with organizations such as Ducks Unlimited Canada (DUC) and Bird Studies Canada (BSC) to collect information on the bird communities that inhabit LP’s wood supply areas in Manitoba and British Columbia. Information obtained through these partnerships—the BSC’s Atlas of the Breeding Birds of British Columbia, for example—will assist LP and others in making more informed forest management decisions that will contribute to long-term conservation efforts for bird populations in Canada. ■ DONNA KOPECKY CANADIAN NATIONAL FOREST RESOURCES ENVIRONMENTAL MANAGER Donna is originally from Thunder Bay, Ontario, where she graduated from Lakehead University with a Bachelor of Science degree and a certificate in Environmental Impact Assessment.

The finished deck may be walked on and will carry construction loads without damage to glue bond. hen floor members are dry (and just prior to the installation W of floor coverings), ensure that fasteners are flush with or slightly below the panel surface to help prevent any nails popping upon drying. “DON’T HIT ME!” —LP TOPNOTCH LP® TopNotch® Sub-Flooring is engineered with a selfspacing tongue-and-groove design that fits together easily during installation. Framers may mistakenly overdrive the sub-flooring together with sledgehammers attempting to close this space. They ultimately damage the product and prevent the rainwater drainage system from working properly. Proper installation helps builders avoid the need to sand the floor due to edge swell from standing water caused by improper draining.
