1.04 SYSTEM PERFORMANCE
A. General: Provide aluminum/wood composite window units that meet or exceed performance requirements specified:
1. AAMA/WDMA 101/I.S. 2-97 Section 2.2.9 Fixed Windows and Section 2.2.5 Casement Windows. Rating shall be: C-AW55 or F-AW55. [ NOTE: Optional High Performance Rating of C-AW80 is available. Please consult H Window Company, LLC]
B. Design Requirements: Comply with structural performance, air infiltration, and water penetration requirements indicated in AAMA/WDMA 101/I.S. 2-97 for type, grade, and performance class of window units required.
C. Testing: Test each type and size of required window unit through a recognized Independent Testing Laboratory or Agency, in accordance with ASTM E283 for air infiltration, and with ASTM E331 for water penetration.
1. Air Infiltration: Exterior windows will not exceed 0.10 CFM per lineal foot of sash crack when tested in accordance with ASTM E 283-99 at a uniform pressure of 6.24 PSF.
2. Water Resistance: No water leakage will occur when windows are tested in accordance with ASTM E 331-00 at a static pressure of 10.00 PSF.
3. Uniform Load Deflection Test: No glass breakage, permanent damage to fasteners, hardware parts, or damage to make window inoperable or deflection of any unsupported span (meeting rails, muntins, frames, mullions, or other appurtenances) in excess of L/175 at both a positive and a negative load in minimum of 55 PSF when tested in accordance with ASTM E330-97.
4. Uniform Structural Load: Unit is to be tested at 1.5 times design wind pressure, both positive and negative at 82.50 PSF in accordance with ASTM E 330-97. There shall be no glass breakage, permanent damage to fasteners, hardware parts or any other damage to make the window inoperable. There shall be no permanent deformation of any main frame or sash member in excess of 2% of its span.
1.05 SUBMITTALS
A. Shop drawings: Submit drawings and product data under provisions of Section 01300. Include dimensions, relationships to construction of adjacent work, air and vapor barrier seal to adjacent construction, component anchorage, type of caulking, window locations, installation methods and installation materials.
B. Submit manufacturer’s installation instructions under provisions of Section 01300.
C. Submit color samples under provisions of Section 01300.
D. Submit samples illustrating operable window and fixed window frame sections, corner section and mullion section.
E. Submit two 12 x 12 inch samples of each type of glazing.
F. Test Reports: Provide certification by a recognized Independent Testing Laboratory showing that each type, grade, and size of window unit complies with performance requirements for air infiltration, water resistance and uniform structural loads.
1.06 QUALITY ASSURANCE
A. Qualifications: Window Manufacturer must certify that the products supplied under this specification have been manufactured for a period of not less than 5 years.
B. Pre-installation Window Test: The owner reserves the right to randomly select one window at the time of delivery and submit it to an Independent Laboratory for testing. Testing will verify compliance of the production run with these specifications. The cost for pre-installation testing shall be paid by the Owner. Any deficiencies discovered on the window by the testing, and deficiencies in any similar models used in the project, will be corrected by the Bidder at no cost to the Owner.
C. Post Installation Field-Testing: Shall be in accordance with AAMA 502-90 using test method A.
1. After installation and before final payment, up to 2%, but not less than 2 windows shall be tested
for air infiltration and water infiltration as specified. Windows will be randomly selected by the Owner on the day of testing.
2. Conduct air infiltration tests at a uniform static pressure of 6.24 PSF. The maximum rate of air
leakage will not exceed 1.5 times the specified air leakage of 0.10 CFM per lineal foot of sash crack for operating windows.
3. Conduct water penetration tests at a static pressure of 10.0 PSF.
4. All costs associated with the Post Installation Field Testing and required repair or replacements shall be born by the Window Contractor. All tests are to be conducted by an accredited Testing Laboratory in the presence of the Owner or the Owner’s Representative.
5. Failure of the window unit or installation to pass these tests shall require the contractor and/or
manufacturer to pay costs necessary for correction, including removal of windows and providing new windows from the same or another manufacturer.
6. If one of the two units fails either test, three additional units shall be tested. If one or more of
the three additional units fails
either test, three more units shall be tested.
This procedure shall continue until all unit tests are passed.
1.07 DELIVERY, STORAGE, AND HANDLING
A. Deliver and handle window units under provisions of Section 01600.
B. Store and protect window units under provisions of Section 01600.
1.08 WARRANTY
A. Window Warranty: Submit a written warranty, executed by the Window Manufacturer, against defects in material and workmanship of the windows under normal use.
B. Glass: Warranty period starts from the date of manufacture printed on the insulated glass spacer.
