ViperVent® CDR is a combined drainage and ventilation mat for roofs and siding. Installed under the roofing or cladding, its polymer core keeps a gap open so moisture drains out and air can move, helping prevent mold, mildew and rot.
50 ft roll (part # 01-X-0007)
For cedar shingles and shakes, metal and standing-seam, zinc, asphalt and fiberglass shingles, SIP roofs and siding
Lightweight; installs with a staple hammer
Wide rolls mean fewer seams
Core does not absorb moisture and resists most corrosive chemicals and solvents
25-year limited warranty
