VIPER CDR VENT™ is a 0.30-inch (7.6mm), randomly oriented, geometric patterned drainage and ventilation mat.

The product is designed to eliminate moisture and moisture vapor in cedar roofing, siding applications, and metal roofing applications.

VIPER CDR VENT is produced from an extruded polymer matrix of tangled monofilaments, which are heat-welded at the junctions to form a structure that spaces siding and roofing away from the inner sheathing.

The product is useful in cedar and metal roofing and siding applications in which a clean airspace is desired for ventilation and drainage.
