CedarVent installation instructions
After the roof/wall is prepared with a vapor barrier over the decking or plywood surface, install a strip of CedarVent around the perimeter* of the roof/wall surface (CedarVent Plus is available and comes with a factory applied fabric insect screen attached-generally used but not required at the perimeter of roofs and walls). Next, install CedarVent strips at the lower edge of the roof/wall parallel with the ground and centered at the nail lines, continue pieces butting each piece against the other until you reach the end. Next…
For roofing: Install the next parallel CedarVent up about 5″ or at the next nailing line for your cedar product being installed (CedarVent installs at the nail lines for your particular roof cedar product) and finally install SmartRidge at the roof ridge for ventilation. Your cedar roof is now properly ventilated with exhaust. If you need additional intake ventilation see our SmartVent product. (see note below)
For Wall: Nail CedarVent over existing vertical studs when installing cedar clapboards. For wall shakes nail CedarVent horizontal over plywood/osb panels and install at horizontal nail lines with cedar shakes. Optional to install CedarVent Plus at the bottom course for insect protection. (see note below)
* Note: Perimeter CedarVent on walls should be 3/8″ short of corner posts and soffits to allow air to escape. For roofs, CedarVent can hang over the edges 3/8″ on the perimeter rake and eave areas.
CedarVent and CedarVent Plus are available in 3/16”, 3/8”, ½”, ¾”, 1”, 1.25” & 1.5”thicknesses and custom orders are always available. Use of RevealTape by DCI can speed placement of CedarVent strips.
