PART 3 EXECUTION

3.1     EXAMINATION

A.      Do not begin installation until substrates have been properly prepared.

B.      If substrate preparation is the responsibility of another installer, notify Architect of unsatisfactory preparation before proceeding.

C.      Examine crates for damage immediately upon delivery.

D.      Examine panels for damage prior to installation.

3.2     PREPARATION

A.      Clean surfaces thoroughly prior to installation.

B.      Prepare surfaces using the methods recommended by the manufacturer for achieving the best result for the substrate under the project conditions.

C.      Treat open ends of panels upon opening crates to prevent dirt or other material from entering glazing.

D.      Verify openings are correct size.

3.3     INSTALLATION

A.      Install in accordance with manufacturer's instructions. For architectural structures use an aluminum glazing system with EPDM or Neoprene gaskets.

B.      Install with extruded ribs vertical with "Exposure Side" to exterior, as indicated on protective film (the printed side should be faced outside).

C.      Remove chips and dust from internal cells with compressed air. Seal open ends with approved sealing tape.

D.      Just prior to installation expose glazing edges by peeling back protective film sufficient for edge bite.

E.      Drill holes minimum 1-1/2 inches (38 mm) from edge, to allow for thermal expansion.

F.       Install in accordance with manufacturer's recommendations for edge bite and expansion allowance.

1.      Minimum Edge Engagement: 1/2 inch (13 mm).

2.      Minimum Edge Engagement: 3/4 inch (19 mm).

3.      Rabbet Depth: Edge engagement plus allowance for thermal expansion. Rabbet depth should be not less than 3/4".

G.      Remove protective film immediately upon completion of installation.

3.4     PROTECTION

A.      Protect uninstalled sheet products from direct exposure to the sun's rays. Exposure to the direct rays of sun will bake the protective masking on to the sheet making removal of the masking extremely difficult or impossible. Sheets should be protected indoors until completion of project with open flute edges sealed.

B.      Touch-up, repair or replace damaged products before Substantial Completion.
