Product Overview

For improved air circulation in the attic, install the Durovent 22 in. x 48 in. Rafter Vent (10-Pack). It can be cut to fit most joist spaces and is an affordable way to meet energy-code requirements for air flow. Use it between rafters to create an air channel through insulation to help keep air flowing freely in your attic.
  • Improves insulation efficiencies, allows for cooler attics in the summer months, drier attics in the winter months and helps prevent ice-dam formation
  • Install between rafters to provide an unobstructed air channel through insulation to keep air flowing from soffits to ridge vents
  • For use in 24 in. or 16 in. rafter or truss applications
  • Excellent option for new construction
  • Can be cut to fit most joist spaces
  • Cathedral ceilings require a continuous run of vents from intake to exhaust with a 1 in. space between each vent
  • Perforated center line to fit most applications
  • Wide nailing flange and center strut allow for easy installation
  • Economical way to meet energy-code requirements for air flow
  • The right insulation can save on energy and heating and cooling bills. Check out our Buying Guide for helpful tips.

This product is designed to allow air flow from the soft up past the insulation. If your insulation is higher than one piece, overlap another piece a bit and staple it in. Keep in mind this is about air flow.

Response from ADO Product ExpertJan 15, 2021
Thank you for your comments, this product is typically used in new construction prior to ceilings being put in place. Our black proVent product is more durable and made for retro or re-insulation of attic spaces.
Good value for the price
They came apart a little and the instructions were not the best. The price however, was definitely excellent!
