Ensure proper attic ventilation and moisture control with the ADO Products rafter vent baffle, designed for easy installation in new or existing construction. Made from durable ABS material, this attic vent baffle helps maintain airflow from soffit to ridge, preventing insulation from blocking air movement and reducing the risk of mold or ice dams. The sturdy construction supports long-lasting performance, making it ideal for use as a rafter vent in attics, garages, or other spaces requiring effective ventilation. Compatible with various roofing materials, this attic baffle fits standard rafter spacing and is suitable for both 14 in. and 22 in. applications. Its lightweight design allows for quick placement, while the integrated channels ensure consistent air circulation throughout your attic space. Use this soffit baffle to improve energy efficiency and extend the life of your roof by promoting a balanced attic environment. Trust ADO Products for reliable attic ventilation solutions that help protect your home and enhance indoor comfort. Review: Great for retrofitting in an existing mid-to-low-slope attic - First, remember that this is a *baffle-less* version of the vent. You will need to form your own baffle at the bottom (using batted insulation typically) to keep air flowing up the underside of the roof and blown-in insulation from covering up the soffit vents. Second, though, installation of these are as easy as they can be. In our case, we are retrofitting a poorly-insulated attic (one existing layer of R19 batted insulation between the joists, for an effective ~R14, completely insufficient for our climate). These being baffle-less easily slide behind the existing batts of insulation to form a good channel for air flow, and are then stapled up to the underside of the roof. Would be very difficult to get into that fairly-low-slope eave with a stapler to staple "down" the baffled ones. Instead, I put additional batted insulation tight up against the outside to keep the vents cleared. Should also note that the length of these *sounds* excessive, until you look at the slope of your roof. In an 8x12 slope roof (meaning, for every foot along the attic joists, the rafter rises 8", or for every 12 feet it goes up 8 feet), to get 20" of depth you will need 36" of rafter vents. If that's you, these are probably sufficient with just one layer! In my attic slope (5 x 12), these rafter vents (48") stuck all the way down (the soffits on our roof are just slightly below the ceiling level for "reasons") gave just about 18" of height, which is then below the level where we want our blown-in insulation to be for an R60 install. So, we need to double-up the rafter vents to get up to the necessary height. This is easy with these vents: install the first one as deep as it goes, then align the second so the last row of "supports" (the round indents that look like egg shell holders) nest, and staple through both where they overlap then on up the second vent. Two of them like this is a little more than 30" total height, which is well above where we are going to be blowing insulation in, allowing for any movement of the blown-in insulation or errors while blowing to not result in insulation clogging the vents. I definitely recommend setting your stapler on the "least deep" setting, as a deep staple setting will just push the staple through the styrofoam (ish) egg crate material of these rafter vents. Are these brittle? The batch I got were not. I mean, if you try to bend it in half it will snap, but other reviews here and on other sites make it sound like these will crumble as you move them around. I had no trouble maneuvering them in the tight space without breaking any of them. Overall, these are a good product at a pretty good price (compared to the alternatives). Just make sure they are a fit for your particular circumstances. If we had a high-angle roof, or were putting this in new construction without any installed "floor" to the attic, I would recommend the similar products with built-in baffles. But these are great for shallow roof lines being retrofitted into attics prior to blowing in insulation. Review: Exactly as Described - great bulk price

They work
I just finished retrofitting these above the insulation in the 45 degree section my half story roof. It was not fun. They are *barely* (sometimes not) sturdy enough to stuff above existing insulation. Any roofing nails sticking down will tear the foam up and if you have thick insulation, the foam doesn't have enough to rigidity to push it down & out of the way. If you find yourself in the same situation, I recommend using a 3" PVC pipe and using it to help brace the foam as you're stuffing it in. And/or, make a feeder panel out of a thin sheet of MDF or ply to push the insulation down enough to ease sliding the foam up.

Worked as described.
Used these to finish a cathedral ceiling project. Saved around $45 vs the big box stores. Will buy again.

Work fairly well
Sizes are correct but thickness ( or lack there of) make them a little flimsy
