Ideal vent for new construction. The extruded polystyrene material provides a lightweight water resistant air channel through your insulation. Improves insulation efficiencies by allowing for cooler attics in the summer months, drier attics in the winter months and helps prevent ice-dam formation. Perforated center allows for use in 16" on-center applications, full size fits 24" on-center applications. Staple to the roof deck on outside flanges and center strut (if using full 22" vent), every 6-8 inches. When using in cathedral ceilings and installing fiberglass batt insulation leave a 1" space between vents.
Economical way to meet energy code requirement for attic air flow aiding in cooler attics in summer and helping prevent ice-dams in winter
Install between rafters to provide an unobstructed air channel through insulation
The ventilation system can be cut to fit most joist spaces
Improves insulation efficiencies, allows for cooler attics in the summer months, drier attics in the winter months and helps prevent ice-dam formation
For use in 24-in or 16-in rafter or truss applications
Excellent option for new construction
Cathedral ceilings require a continuous run of vents from intake to exhaust with a 1-in space between each vent when installing fiberglass batt insulation
Perforated center line to fit most applications
Wide nailing flange and center strut allow for easy installation
