Product Details

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 1 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.

Q:What is the R value for these baffle vents?
by|Jan 19, 2023
4 Answers
Answer This Question

A:  Polystyrene has an R value of 1 per inch. I would give these about a .1 ish in themselves. What is harder to measure is the airflow and air gap benefit. I am using these in a cathedral ceiling to allow air flow from open eaves all the way to the ridge.

    A:  Hello Aaron, Owens Corning Raft-R-Mate is an extruded polystyrene foam vent designed to assure unrestricted airflow from the soffit to the ridge vent. It is not considered insulation and does not have an R-value. Thank you for your inquiry!

      A:  Poly Styrene has an R Factor of 1 per inch of thickness. There is some R in these, but not much. I would give it overall .1 ish.

        A:  Think of it this way, a really hot cup of tea of coffee in a Styrofoam or cardboard cup. Wrap another layer of each around them. Not much different! perhaps 0.001 R value. The baffles are meant to draw air unobstructed from the soffit vents outside to the attic allowing for a good flow. This of course presuming you have good ridge-gable end or roof vents!

          A:  Hello West, the Raft-R-Mate is perforated in the middle so it can be split into two pieces. The half piece is 11.25" wide and will provide 11.15 square inches of net free vent area. Thank you for your inquiry!

            Answer This Question

            A:  These are designed for either. The full piece fits 24” oc bays, but they can be separated down the center perforation if you need a smaller channel for 16 OC bays.

            by|Dec 29, 2022

              A:  No its for 24" center

              by|Dec 29, 2022

                A:  They’re made out of a styrofoam type material and can be cut with a utility knife.

                  A:  Hello Raul, Due to its symmetrical design, Raft-R-Mate® attic vent can be split in half for 16-inch o.c. rafter spacing. Thank you for your inquiry!

                    Q:I have a 2x6 rafter. If I use the baffles the space will be reduced. I?m thinking R19 won?t fit. Should I use the baffles and a R13 in that space so that it will fit ?

                    Answer This Question

                    A:  Hello Pete, installing the Raft-R-Mate into a 2x6 cavity will create a cavity that is approximately 4" thick. Compressing a R-19 into a a 4" cavity will reduce its R-value to approximately R-14. Owens Corning manufactures a R-15 at 3.5" that will not be compressed. Thank you for your inquiry!

                    by|Oct 18, 2022

                      A:  The baffles/spacers are typically used along the eaves to ensure the ventilation gap is maintained underneath the decking, but can be installed along the entire length of the decking. With 2x6" rafters, you will lose approximately 1" of space. R13 is designed to fill a 3 1/2" space, meaning there would be some uninsulated space if used in the 2x6 rafters with the baffles installed. Might be better to use R19, R21 or R23 insulation designed for 5 1/2" spaces and just let it compress slightly. You may lose a little R factor, but it would probably be better than having uninsulated space between the batts/blankets and baffles. Here is a reference chart on what is available from Owens Corning, https://dcpd6wotaa0mb.cloudfront.net/mdms/dms/Residential%20Insulation/10024567/10024567-PINK-Next-Gen-Fiberglas-Insulation-Product-Data-Sheet.pdf?v=1647850967000

                      A:  The baffles and R-13 are the way to go. Otherwise you might compress and collapse the baffles. 

                      by|Oct 20, 2022

                        A:  The baffles are to keep blown insulation from blocking the bird blocks in the soffit vents so shouldn't affect R value of insulation used in the attic. If using batts you shouldn't have the air blockage issue.

                        by|Oct 20, 2022

                          A:  These baffles are about an inch thick. I used them with R19 in my rafters which are also 2x6, perfect fit.

                            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.
