	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.
	** NOTE TO SPECIFIER ** The incorporation of a vapor barrier or retarder within the roofing assembly is highly recommended when the project is located in Zones 1, 2 or 3 of the United States. H-Shield is not intended to substitute for a vapor barrier. Vapor barrier or retarder when used shall have a perm rating of 0.5 or less as determined by ASTM E-96.

	3.3	INSTALLATION
		A.	Install specified insulation in accordance with manufacturer's latest printed instructions and as required by governing codes and Owner's insurance carrier.
		B.	Do not leave installed insulation exposed to weather. Cover and waterproof immediately after installation.
		C.	Seal exposed insulation joints at the end of each day. Remove seal when work resumes.
		D.	Remove installed insulation that has become wet or damaged and replace with new solid and dry insulation material.
