GreenGuard Roofing Cover Board

Attic Rafter Vents

GreenGuard Attic Rafter Vents are designed to install between rafters to prevent clogging of the path from soffits to the attic wnen insulation is blown in. For finished attics, they can be attached behind the insulated area to create a backer for insulation and a channel for air movement through to the top venting area.
 

  • Helps maintain a constant flow of air through soffits to the attic
  • Prevents blockage of air flow by blown-in insulation
  • Does not absorb water, rot or deteriorate
