raft-R-mate® and AtticMate®

Owens Corning’s raft-R-mate® and AtticMate® products are extruded polystyrene foam vents designed for 16” or 24″ on center framing.

  • Pictured is the raft-R-mate which has a bend down air stop/insulation block to prevent loosefill insulation from blocking the soffits and it also stops “wind wash” from blowing insulation off the top plate
  • Extruded foam will not crush or shatter like the expanded foam (white) vents
  • Center score to easily snap in two as needed


Brentwood Industries’ AccuVents effectively conduct air up from the soffit along the roof sheathing above the insulation. The chutes’ built-in wind wash barrier keeps the soffit free from drifting insulation.

  • Available for 16″ or 24″ on center framing for standard or cathedral applications
  • Made from 100% recycled flame retardant PVC
  • Meets ENERGY STAR® Thermal Bypass requirements

*Soffit blocks also available for spray foam applications
