Product Overview

Owens Corning Raft-R-Mate attic vent is an extruded polystyrene foam vent designed to assure unrestricted airflow from the soffit to the ridge vent. Additionally, Raft-R-Mate attic vent has an optional bend down air stop or insulation block at the top plate of the wall in one easy-to-install product. The optional air stop or insulation block prevents loose fill insulation from filling the eave space during installation of cathedral ceiling or attic floors, by closing off the opening below the Raft-R-Mate attic vent to the soffit. The Raft-R-Mate attic vents install quick and easily and are sized to fit 24 in., 16 in. and 12 in. on center framing. Utilize in both new and retrofit construction.

    Asked by Joe June 1, 2021

    Answer

    Hello Joe, The Raft-R-Mates can be used in retrofit applications also. However, the lower the slope of the roof, the more difficult it will be to get back there and add the Raft-R-Mates. Make sure you use caution, using a piece of OSB to bridge the joist may make it easier and safer. Thank you for your inquiry!

    Answer

    Hello RustySpurr, When installing Raft-R-Mates Owens Corning recommends installing them in all bays. The Raft-R-Mate has a hinge that can be folded down and staples to the top plate to prevent insulation from falling into the soffits and blocking ventilation. Thank you for your inquiry!

    Asked by WallE January 12, 2021

    Answers

    Not sure about the sizing question. This item is used as a spacer to create a channel for airflow between the roof and the insulation, not as insulation in and of itself. Theoretically it could be used but the R-factor would likely be minimal.

    What size staples should be used for installation?

    Asked by Matt January 4, 2021

    Answer

    Hello Matt, When installing the Raft-R-Mate you will want to use coated roof staples at a maximum of 3/8". Please see link below for installation instructions. https://dcpd6wotaa0mb.cloudfront.net/mdms/dms/Residential%20Insulation/20314/20314-raft-R-mate-Attic-Rafter-Vent-Brochure.pdf?v=1584977984000 Thank you for your inquiry!

    How do I do insulation with spray foam

    Asked by Rick September 24, 2020
    2
    Answers

    I am a little confused by your question. The product listed is not a spray foam product. Additionally, Home Depot sells spray foam products, but they are in a can, and used for small individual jobs like filling cracks. I don't believe Home Depot sells the foam insulation products to insulate an entire attic. I suggest you call a contractor to do such work.

    Hello Enginerd, best practice would be to bring the raft-R-mate vents down to the top plate. Thank you for your inquiry!

    Are these designed to be torn in half for 14 1/2” rafter openings?

    Asked by Mike July 10, 2020

    Answer

    Hello Mike, that is correct, raft-R-mate attic vents can be split in half to fit 16” o.c. framing. Thank you for your inquiry!

    How far up should these go? Essentially I’m asking if I need two per truss since with the fold, it will only go 3 ft up.

    Asked by Brent May 25, 2020

    Answers

    I guess it depends. I have a 40s bungalow. I have 3 per rafter space, per side. 1 at the eaves is enough to allow for quite a thick layer of insulation, even with the fold. I needed to additional 2 to travel from the crawl space through the sloped ceiling to the attic (ridge vented). I don’t know if that helps you, but I’m happy with the product and my results. The roof is venting well.

    Performance. There is no comparison to the rigidity, thickness and design. As I slid these into position, the directed air flow was amazing having a nozzle effect, increasing velocity of air from soffit vent and directing it up toward the ridge vent.. It works. The price made me hesitate and Home Depot only sells online by the 70 pc. case. Having installed these now, I wouldn't hesitate to buy again. Superior. Installation. . The competitor's products are thin, flimsy, and brittle copys. These stayed in place in my 24" on-center rafters. I used an air stapler with Arrow T50 3/8 x 3/8 crown staples .I used the divergent grind points that give a little twist and hold great. Go to Arrow's website for more on metals and point types available. Stapling into deck sheathing with a Porter-Cable air stapler only drove the staples the depth needed. It didn't punch thru foam baffles, just good firm hold. Sliding insulation into position at edge of top plate, the rafter vents are rigid keeping airspace between roof deck sheathing and insulation and didn't rip/tear or crush and I had R-30 thick batts shoving into that cramped space. This product maintains airflow from soffit vents as designed. Features.. Owens-Corning rafter vents have an acordian portion that can be curved down to the top plate as a wind block. This keeps loose fill insulation from being blown back away from edges near soffit vents and when blowing new insulation into edges, it prevents the loose fill insulation from getting blown into soffit vent area plugging up the vents. To recap, the rafter vents work great and do exactly what they are designed to do, protect and provide the airspace needed for inlet air from soffits. I hope this helps you make an informed purchase.

    The rafter bays I was insulating were from 1890, so none of them were the same width and none of them were standard 16" centers. I had to improvise but was able to do so fairly well with these. 1/2" staples for the install and I was done. Easy to trim as well with a good sharp razor.

    They do the job, however when bending them to attach to the eaves and the floor joists they tend to crack and split. Not the easiest thing to manage in a tight space.

    I live in a rancher and wanted to blow in insulation. I found my pitch too low to use the rafter mate as planned I had to lay flat on stomach and try to staple to the sill then truss. They just kept shredding on the nails and from me pushing them in. Would be great for steep pitch or new construction. I took r30 rolls cut to truss width then placed a rafter mate cut in half lengthwise in then used the r30 to take up the space and am going to use that as my block so the blown in doesn’t get into the soffit eaves and still gives me the ventilation of the rafter mate.
