PART 3: EXECUTION

3.01 INSTALLATION

A. Inspect window openings prior to beginning installation. Verify that the openings are level and plumb and that the minimum opening dimension (width or height) is 1/4” larger than the window unit. Proceed with installation only after unsatisfactory conditions have been corrected.
B. Install window units in accordance with manufacturer’s recommendations, installation & Finishing Instructions and approved shop drawings.
C. Secure assembly to framed openings, plumb, level and square, without distortion. Provide proper support and anchor securely in place.
D. Place batt insulation in shim spaces around window perimeter to maintain continuity of building insulation. Do not use expanding foam insulation.
E. Apply sealant and related backing materials at the exterior perimeter of the window units.F. Leave window units closed and locked.

3.02 PROTECTION AND CLEANING

A. Clean window frames, sash and glass promptly following installation. Avoid damaging protective coatings and finishes. Remove excess sealants, dirt and other substances.
B. Protect window surfaces and hardware from contact with contaminating substances, such as masonry cleaning solutions. Contact with certain substances can cause damage to the glass surface and/or could cause seal failure of the insulating glass unit. These substances could also cause discoloration or damage to painted surfaces. Clean contaminated surfaces immediately after contact.
