Rmax Advantage Vented Nailable Base-3
Above the Deck Insulation

In this two-step Vented Nailable Base-3 system, the insulation with glass fiber/organic mat facers is installed first, followed by a separate OSB nailing surface with factory attached furring strips.   

Advantage Nailable Base-3 is used in steep slope roofing applications and is applied to the roof structure in order to provide a layer of continuous thermal insulation and increased moisture protection.
