SmartBaffle 16 Attic Insulation Baffle for 16" Rafter Bays

After finding that the plastic insulation spacers at the big box stores are flimsy and will collapse to easily I decided to try these for my 16 “ on center roof trusses. They are plenty strong and allow great versatility in odd shaped areas. I installed them with ss lathe screws which worked very well. As someone who tends to overbuild they even pleased me LOL.

I have been searching a long time for baffle inserts to place in my roof baffles. This product is superior to any baffle product out there that you can get. Thank you so much for making a great product.

Used these to update soffit ventilation when getting a new roof. They worked perfectly. They are more rigid than the Home store version. They solve the problem of insulation crushing them and choking air flow. The rigid design allows for fitting in between rafters and joists design—instead of trusses.

Very sturdy and easy to cut. You can’t use baffles from the big box stores and cut them to fit or hope they won’t collapse. I purchased two different kinds and they’re useless. The distance between our rafters were between 5” to the standard 16” on center. Unfortunately most weren’t. After cutting and scoring, they are still sturdy and won’t collapse with the insulation. We under estimated how many we needed (twice) so this is my third order. Cant say enough about this product. I won’t be worrying my attic is getting ventilation. Worth the extra expense.

These are made out of double wall corrugated plastic. My only concern is that being only 3' long I will need 216 for my attic. The boxes are 36 pieces each. These leave a substantial channel, but the flip side of that is that they also reduce the amount of insulation you can use. With the other baffles I have used I only lose about 1" of insulation. I also wonder if these will be pressed in in the middle by the insulation if it is too tight. The others all have central support, but they also aren't as strong as these, not by a long way. But these are the best I can get on Amazon right now.These don't deal with sealing the eaves. Another brand I use has end pieces which fold around to seal the bottom end. I could do that with these but I'd lose a lot of length too. Then I'd need another box to make the ends. The jury is out on that one until I try cutting them to bend.All in all though, a very high quality option.

Good

Easy to installMuch better than what you can find in big box storesWould recommend if you need ventilation in attic

In May 2021 I purchased 55 smart baffles. This was part of my attic insulation project where the existing blown in insulation and cardboard baffles were removed and all attic holes and seams were air sealed. Finally new blow-in insulation was added to a depth of 15 to 17 inches to give about an insulating value of about R40.I loved your baffles, Our roof is 10/12 pitch so the baffles were installed slightly different from your web site. The photo below shows the baffle insulation I used. The two baffles on the right was the final installation method that I used. The edge of baffle flange was flush to the bottom of the joist and gave about a 4 inch air gap between the roof and baffle. The baffles to the left side shown in the photo was used for about 15 baffles. However the baffle extended about two inches into the soffit. After discussing the insulation with the factory I changed the installation so that the baffle was flush with the back side of the top plate. The 15 baffles were removed and repositioned to look like the two in the right side of the photo.I needed a few narrow baffles. I cut the routed kerf on a table saw to make a new bend. The table saw blade was set to make about a 1/16 inch deep kerf. These narrow baffles looked great. Finally I tried several methods of securing the baffles to the joists and plate. I ended up using 1 inch lath truss screws. I used interior type of screws. I considered using stainless but probably these will never rust.Thanks again for making a great product and for your help. I also sent photos of the installed baffles to the insulation company and highly recommended them instead of cardboard baffles which they normally install.
