GENERAL NOTES
HANDLING, STORAGE AND PROTECTION OF ALUMINUM
The following precautions are recommended to protect the material against damage. Following these precautions will
help ensure early acceptance of your products and workmanship.
A. HANDLE CAREFULLY.
AII aluminum materials at job site must be stored in a safe place well removed from possible damage by other
trades. Cardboard wrapped or paper interleaved materials must be kept dry.
B. CHECK ARRIVING MATERIALS.
Check for quantity and keep records of where various materials are stored.
C. KEEP MATERIAL AWAY FROM WATER, MUD AND SPRAY.
Prevent cement plaster or other materials from damaging the finish.
D. PROTECT THE MATERIALS AFTER ERECTION.
Protect erected frame with polyethylene or canvas splatter screen. Cement, plaster, terrazzo, other alkaline solu- tions and acid based materials used to clean masonry are harmful to the finish. lf any of these materials come in contact with the aluminum, immediately remove with water and mild soap.
United States Aluminum Corporation warrants its High Impact Glazing Systems to perform at the published values for air and water infiltration and structural
performance. Testing standards allow for unit inter layer a maximum rip size after impact and cycle testing. Though considered as successfully passing the test,
water infiltration can occur through the glazing material in such cases. United States Aluminum does not warrant any glazing materials resulting from impact from
wind borne debris and subsequent cycling under storm conditions.
When using this product, United States Aluminum Corporation recommends specifying a uniform overall glazing thickness of plus or minus .004” over the entire
area of the glazing unit. This must include edges and center of unit. It is critical to check the glazing unit prior to glazing to insure the proper thickness of the
inter layer. Glass must be two pieces of 1/4” thick, heat strengthened with a.030 pvb for DOD or .090” polycarbonate interlayer for hurricane requirements, 1/2”
air space and 1/4” thick, heat strengthened out board light.
Due to the diversity in state/provincial, local and federal laws and codes that govern the design and application of architectural products, it is the responsibility of
the individual architect, owner and installer to assure that products selected for use on projects comply with all applicable building codes and laws. United States
Aluminum exercises no control over the use or application of its products, glazing materials and operating hardware and assumes no responsibility thereof.
The rapidly changing technology within the architectural aluminum products industry demands that United States Aluminum reserve the right to revise, discontinue
or change any product line, specification or electronic media without prior written notice.
NOTE: Dimensions in parentheses ( ) are millimeters unless otherwise noted.
Other metric units shown in this manual are:
m - meter Kg - kilogram
Pa - pascal KPa - kilopascal
MPa - megapascal

GENERAL INSTALLATION NOTES
Recommended guidelines for all instAllAtions:
1.
REVIEW CONTRACT DOCUMENTS. Check shop drawings, installation instructions, architectural drawings and shipping lists to become thoroughly familiar with the project. The shop drawings take precedence and include spe-
cific details for the project. Note any field verified notes on the shop drawings prior to installing. The installation
instructions are of general nature and cover most conditions.
2. INSTALLATION. AII materials are to be installed plumb, level and true.
3. BENCH MARKS. AII work should start from bench marks and/or column lines as established by the architectural drawings and the general contractor with guaranteed accuracy. Working from these datum points and lines deter
mine: a) The plane of the wall in reference to offset lines provided on each floor.
b) The finish floor lines in reference to bench marks on the outer building columns.
c) Mullion spacing from both ends of masonry opening to prevent dimensional build-up of daylight opening.
4. STEEL ANCHORS. Steel anchors that weld to steel structure are normally line set before mullions are hung.
Outstanding leg of anchors must be at 90° to offset lines. Mullion space should be held to ±1/32” (0.8). Anchor clips vary per job conditions. Follow approved shop drawings for size and location of clips.
5. FIELD WELDING. AII field welding must be adequately shielded to avoid any splatter on glass or aluminum.
Results will be unsightly and/or structurally unsound. Advise general contractor and other trades accordingly. AII field welds of steel anchors must receive touch-up paint (zinc chromate) to avoid rust.
6. SURROUNDING CONDITIONS. Make certain that construction which will receive your materials is in accordance with the contract documents. lf not, notify the general contractor in writing and resolve differences before proceed- ing with work.
7. ISOLATION OF ALUMINUM. Aluminum to be placed in direct contact with uncured masonry or incompatible ma terials should be isolated with a heavy coat of zinc chromate or bituminous paint.
8. SEALANTS. Due to stringent guidelines, silicone sealant requirements for impact glazing systems must be:
Tremco Spectrum II or DOW 795 for all metal to metal and perimeter seals.
Tremco Proglaze SSG or DOW 995 for all glass to metal structural adhesion.
Consult with sealant manufacturer for recommendations relative to joint size, shelf life, compatibility,
cleaning/priming, tooling, adhesion, etc. It is the responsibility of the Glazing Contractor to submit a statement
from the sealant manufacturer indicating that glass and glazing material have been tested for compatibility and
adhesion with glazing sealants, and interpreting test results relative to material performance, including recom mendations for primers and substrate preparation required to obtain adhesion. The chemical compatibility of all
glazing materials and framing sealants with each other and with like materials used in glass fabrication must be
established. This is required on every project.
9.
FASTENING. Within the body of these instructions “fastening” means any method of securing one part to another or to adjacent materials. Only those fasteners used within the system are specified in these instructions. Due to the varying perimeter conditions and performance requirements perimeter and anchor fasteners are not specified in these instructions. For perimeter and anchor fasteners refer to the shop drawings or consult the fastener sup- plier.
10.
BUILDING CODES. Due to the diversity in state/provincial local and federal laws and codes that govern the design and application of architectural products it is the responsibility of the individual architect owner and installer to
assure that products selected for use on projects comply with all the applicable building codes and laws. United States Aluminum exercises no control over the use or application of its products glazing materials and operating hardware and assumes no responsibility thereof.
11.
EXPANSION JOlNTS. Expansion joints and perimeter seals shown in these instructions and in the shop drawings are shown at normal size. Actual dimensions may vary due to perimeter conditions and/or difference in metal tem-
perature between the time of fabrication and the time of installation. Gap between expansion members should be based on temperature at time of installation.
12.WATER HOSE TEST. As soon as a representative amount of the wall has been glazed (500 square feet or 46.5 m2) a water hose test should be conducted in accordance with AAMA 501.2 specifications to check the installation. On all jobs the hose test should be repeated every 500 square feet (46.5 m2) during the glazing operation.
13. COORDINATION WITH OTHER TRADES. Coordinate with the general contractor any sequence with other trades which offset curtain wall installation (i.e. fire proofing, back-up walls, partitions, ceilings, mechanical ducts, con
verters etc.).
14. CARE AND MAINTENANCE. Final cleaning of exposed aluminum surfaces should be done in accordance with
AAMA. 609.1 for anodized aluminum and 610.1 for painted aluminum.

Measure rough opening to determine frame width and height dimension. Measure rough opening vertically in
multiple places to determine shortest dimension. Allow a maximum of 1/2” (12.7) caulk space at head and jambs.
See approved shop drawings for all other caulk space allowances. Shim subsill as required for leveling.
Subsill length is determined by entrance locations. Subsill butts to door jambs. Determine last bay
installation and allow 1/8” (3.2) additional length to subsill. See Detail A & B.
Cut members to length:
Subsill length without entrance = Frame Dimension plus 1/4” (6.4). Subsill must extend 1/8” outside last wall jamb to allow last bay installation.Subsill runs through. See Detail B.
