Since 1979, Thermolite has been a leading innovator in supplemental interior window systems. We
are a GSA-certified contractor and work with governmental agencies, the U.S. military, commercial
renovators, hospitality facilities and historical preservation projects.
The cornerstones of our product all revolve around ENERGY and are represented in the colors of
our square logo and are SAVINGS, EFFICIENCY, INTEGRITY AND SECURITY.
Our patented Thermolite Window System is a one-of-a-kind alternative to traditional replacement
windows. This 100% customized window system is designed to provide superior protection
against bomb blast, audio espionage and hurricanes while reducing noise, sealing the building
envelope and preserving historic architectural integrity.
The system is installed quickly, using a process that provides discreet and non-intrusive
installation. In fact, many of the systems can be installed during evening or off-peak hours for
your convenience and security. Contact us now to see if you qualify for a free supplemental
window.

WINDOW DESIGN - GENERAL
A.
A generic design is for the Contractor's information only. The provision of this design does
not relieve the Contractor of the responsibility to retain appropriate consultants and perform
all calculations and design activities necessary to comply with the requirements of this
performance specification.
B.
Requirements for aluminum windows, terminology and standards of performance, fabrication
and workmanship are those specified and recommended in ANSI/AAMA/NWWDA 101/I.S.297 and applicable general recommendations published by AAMA.
** NOTE TO SPECIFIER ** Our blast window is truly special. It is the only one made in the United
States that uses dynamic loading to accomplish the objective of keeping glass from penetrating
into the building. The other dynamic product is made in Israel and all other products simply place
a rigid body into the window and heavily reinforce the window and wall opening. Our window
requires the least amount of anchoring in the world and is patent protected in the USA and EU.

** NOTE TO SPECIFIER ** RetroWAL™ a Revolutionary High Performance Curtain Wall Retrofit
System
Thermolite has launched a revolutionary glazing retrofit system that enables rapid ROI for the
commercial energy efficiency retrofit market. RetroWAL™ is designed to retrofit any curtain wall
or storefront application and is ideally suited for historic and landmark projects as it allows
preservation of the existing facade. RetroWAL™ consists of a "Window Attachment Lite" or
"WAL" which is easily installed on the inside of the existing glass in as little as 30 minutes and
greatly minimizes disruption to building occupants or tenants. The product increases the thermal
performance of single pane windows in commercial buildings, improving center of glass R-value
from R-1 up to R-3 (U-factor 1 to 0.37) with the basic system. Air infiltration is reduced to between
.01 and .04 cfm per square foot of window space. Solar heat gain is controlled by using between
glass blinds and/or window film laminated on the opposite side of the low-e coating or the
existing building glass.
The RetroWAL™ patent pending design places composite caps around the frame with thermal
breaks reducing the conductivity of the aluminum dramatically. Typical curtain systems in older
buildings have R values (resistance to heat loss) of less than R=1. This value is only the same as
1/4" Styrofoam. ThermoWAL™ triples the insulating value of the existing older systems,
outperforms many total replacement options at a fraction of the cost. It adds minimal weight to the
existing curtain wall structure which is often limits the building options.
Security variations for curtain wall structures have been implemented by Thermolite for years and
are now available for the commercial building market.
Security variations for curtain wall structures have been implemented by Thermolite for years and
are now available for the commercial building market:
BlastWAL™: Protects against blast pressures exceeding GSA and DOD standards over 12 psi.
FireWAL™: Protects against active shooter entry into storefront, and curtain wall lobby glass.
StormWAL™: Hurricanes and Super Storms cannot penetrate our glass and frame retrofit system.
Designed to withstand 159 mph winds and higher 3 second gusts. Delete if not required.
