Product Overview

Owens Corning’s 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.

Could you not use these to enclose the rafters from the main part of your attic so there are open runs behind them to carry ventilation from soffit vents up and out the ridge venting?
Asked by: TomTom
Yes. These are somewhat flexible, enabling them to bend to fit where the exterior walls meet the roof. This allows the heat to rise between the baffle and roof decking to the ridge vent.

What’s the R value of these things? Thickness? Material? Actually, With thickness and material, I can calculate R value

Asked by: Gabo2nd
There is no R value with this item. These are designed to be installed on the underside of the roof sheeting so the insulation doesn’t make contact with plywood. Creates an air space to keep the roof shingles cool and the plywood dry. They are very thin and require insulation to be installed over them. They are made of a light weight foam material about 1/8 thick and stand about 2” tall. They are 11 inches wide when separated for 16 on center garters or 22 wide when used together for 24” on center rafters. 4’ long.

how do I install rafter vents with roof nails coming through?
Asked by: DIYER
Just press them in place over the nails and let them pop through. Staple in place as normal. It will not affect the effectiveness of the product.

My attic rafters are 16 on center, so if I buy these which are 22.5 inches wide then I would split them down the middle to use in the bay space, correct. Thanks
Asked by: Millsy
I would purchase the ADO Provent 14" x 4' rafter vent instead. They will completely fill the open space between the rafters and provide more air circulation. Model # UPV14480 Internet # 100533902 Store SKU # 739684

Raft-R-Mate 22-1/2 in. x 4 ft. Attic Insulation Rafter Baffle Proper Vents (10-Pieces) is rated 4.0 out of 5 by 75.
Rated 3 out of 5 by from ok product, difficult to install Previous homeowner blew fiberglass insulation to edges of the attic, blocking the soffits. My attic had moisture problems due to this. I installed these in the rafters to get air flowing from the soffits. Due to the low slope of my roof, this was an AWFUL job. AWFUL. My rafters were 14" spacing, so it worked out fine to use half a piece. I found that the rafr-r-mate tore too easily. Sometimes it tore when folding the accordion portion that folds back to block the air. I purchased a stanley power stapler, which was nice, but it was still very challenging to reach my hand in to do the last few staples at the bottom. If you have a low roof, be prepared for a VERY tough job. If your roof is steep, these should be easy. If you have blown in fiberglass insulation, make sure to use proper PPE including an N95 face mask, eye protection, etc. After installation, I blew in an additional 12" of atticat, which was a relatively easy job.

Rated 5 out of 5 by from Pretty Good Product I just installed these in my home that was built in the mid 70's with more blown in insulation. The install was straight forward and pretty simple. They are a little more durable than you would think for a thin piece of Styrofoam. Couple tips I would give are: if you are putting these in an existing space that has some insulation there already, on the end that goes toward the soffit, miter the end at a 20-30 Degree angle so it doesn't catch or hang up on the way to position. Also a small broom handle or a 1 by, to aide in pushing the product down off of the nails that stick thru from the roof shingles, will help quite a bit. Use a 3/8 staple and you are golden.

Rated 1 out of 5 by from Keep Looking The design concept is there but the installation execution needs much improvement. I tried to install these as designed and no way could I get them to work. Folding the staple tag is impossible due to the corrugations - it will fold with two hands but pops right back when you release either hand. The hinge is very difficult to flex and install. These fit between standard truss systems. My top truss cords were 2x6 with a 6:12 roof pitch and my ceilings were removed so I had plenty of access to make these work. Keep in mind that the actual ventilation flow is limited to the flute profile when installed as recommended - about 2 inches vs. the 5.5 inches I had with the old cardboard style baffle that mounted on the truss cord. I ended up installing these with a string to the underside of the trusses vs. to the underside of the sheathing to maximize my air flow. I should have returned these.

Rated 5 out of 5 by from Good product..easy install.... I only had to install about 25 of the 30 purchased. It was not a "fun" job by any means, but it wasn't really difficult. Do wear a dust mask, tie a string to you razor knife (mine got buried and not found!) and keep extra staples close. I also had a piece of plywood to go across the rafters that allowed me to lie (somewhat) comfortably to install the vents. Took the better part of 4 hours to install. Now to get the blow-in insulation and complete the process!!

Rated 4 out of 5 by from Works well. Needs improvements Works quite well for the intended purpose and the flexible lower section makes it easy to place it over eave vents. This should enable me to blow a full foot of insulation in my attic without blocking the vents. But improvements are needed, particularly: 1. The foam they're made of tears easily. There should be reinforcement where staples are used. I'm doing that myself with duct tape, but it is a slow and laborious process. 2. There should be a version with reflective foil on both sides. That'd allow this product to become a radiant heat reflector in winter as well as a channel for heated air in the summer. Others are making similar products. If Owens-Corning wants to stay competitive, they need to improve this product.

Rated 2 out of 5 by from Does not fit 16" o.c. rafters Pro: The "air stop" flap and accordion shape makes these convenient for stapling to the top plate of an exterior wall. Cons: Although advertised to fit 16" on-center rafters when separated at the perforation, each piece is too narrow, leaving >1" gaps on each side of the vent. These gaps should be plugged before blowing in loose insulation. Also, it is easy to damage the two halves when tearing them apart at the perforation.
