Ample Supply: 10 insulation baffles, perfect for 22 1/2-inch rafter bays (24-inch on-center), ensuring sufficient coverage for most projects. Durable Material: High-hardness PP material resists damage, heat, crushing, tearing, and breaking, offering long-lasting durability. Perfect Fit: Sized at 36" x 26.5" x 0.16", these baffles fit snugly into 24-inch rafter bays for optimal insulation. Ventilation Function: 2-inch air channel prevents insulation blockage, balancing airflow and insulation for a healthy attic environment. Easy Installation: Installable from the rooftop or attic, spray foam adheres well. Baffles can be cut in half for double eaves coverage and bent to serve as a weather barrier.

• 【PERFECT FOR SHEDS & SPOT REPAIRS (10-PACK)】Designed specifically for smaller projects like backyard sheds (8'x10'), playhouses, or replacing broken vents in your attic. This 10-piece set is the ideal "trial size" to fix problem areas without buying bulk. Stop replacing crumbling foam vents year after year; swap them once with our rigid Polypropylene (PP) and solve the problem forever.
• 【RIGID PP MATERIAL - WON'T CRUMBLE】Unlike cheap Styrofoam or thin Polyethylene (PE) that degrades over time, our high-hardness Polypropylene construction is built to last. It is resistant to moisture, rot, and pests, making it the ultimate upgrade for repairing old, damaged ventilation channels in your roof.
• 【HEAT-RESISTANT & WARP-PROOF】Attics get hot, but our baffles stay tough. With a melting point far superior to standard PE (~320°F vs 170°F), these vents will not soften, sag, or warp during peak summer heat, ensuring your small structure maintains proper airflow to prevent overheating.
• 【COMPATIBLE WITH SPRAY FOAM】Even for small repair jobs, you need a vent that holds its shape. Our rigid design withstands the expansion pressure of spray foam insulation without collapsing—something generic foam baffles simply can't do. It guarantees a clear 2-inch air channel every time.
• 【EASY "SCORE & SNAP" FIT】Designed for approximately 22 1/2-inch wide rafter bays,sized for standard 24" on-center rafter bays. For narrower spaces or odd corners, the PP material is easy to modify: just score with a utility knife and snap for a clean, custom fit. Quick installation for DIYers and homeowners.
• 【MAXIMUM AIRFLOW EFFICIENCY】Fits strictly 24" rafter bays for maximum ventilation efficiency. By ensuring a consistent air wash from soffit to ridge, these baffles help balance attic temperatures, reduce AC costs, and prevent moisture damage. The preferred choice for energy-efficient home retrofits.
