Grace Construction Products offers Vycor® Basik™, a granular-surfaced, self-adhered roofing underlayment. The product is suitable for application under traditional roof coverings requiring protection from the wind-driven rain of strong storms. It also provides code-based standards of protection from ice dams in moderate climates. The membrane is backed by a split plastic release liner that protects its adhesive quality. The liner is easily removed, allowing the rubberized asphalt to be bonded to the roof deck.
