GENERAL INFORMATION
• Store insulation inside or protect with a tarp to keep dry
until use. Prolonged exposure to water or moisture may
discolor the surface.
• Minor scratches and/or nicks may occur during installa-
tion. Also, the edges of the foil facer may become slightly
curled. This does not affect the product’s overall perfor-
mance.
A coat of good quality latex acrylic or latex enamel paint
can be used to touch up the boards, and no primer is
required. Follow paint manufacturer’s recommendations
for best results.
