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.
Dissimilar material protection.
1.
Where aluminum will contact dissimilar metals, protect against galvanic action by painting contact surfaces with primer or by applying sealant or tape recommended by manufacturer for this purpose.
2.
Where aluminum will contact concrete or masonry, protect against corrosion by painting contact surfaces with bituminous paint.
3.
Where aluminum will contact pressure-treated wood, separate dissimilar materials by methods recommended by manufacturer.
3.3
INSTALLATION

B.
Coordinate with installation of roof deck and other substrates to receive skylight units
C.
Provide thermal isolation when components penetrate or disrupt building insulation. Pack fibrous insulation in rough opening to maintain continuity of thermal barriers.
D.
Coordinate with installation of vapor barriers, roof insulation, roofing, and flashing as required to assure that each element of the work performs properly and that combined elements are waterproof and weathertight.
E.
Align skylights level, free of warp or twist, maintain dimensional tolerances.
F.
Anchor units securely to supporting substrates, adequate to withstand lateral and thermal stresses as well as inward and outward loading pressures.
G.
Counter Flashing: Where counter flashing is required as component of the skylight, install to provide an adequate waterproof overlap with roofing or roof flashing. Seal with thick bead of mastic sealant, except where overlap is indicated to be left open for ventilation.
 
** NOTE TO SPECIFIER ** Include the following paragraph for residential skylights and delete if not required.
