A Full (2) two inch channel for maximum airflow

SmartBaffle is available in 16” and 24” stock sizes. These insulation baffles are strong, durable, easy to work with and can be used in new construction or retrofit during renovations.

SmartBaffle 16 out-of-the-box size is 18.5”W X 37.5”L X 4mm (thick) and is constructed of rigid, corrugated plastic with two bending routes each route at 2.25” in from the long edge. After installed, the SmartBaffle is 14″ wide with 2″ flanges. These insulation baffles are strong enough to support spray foam expanding insulation creating the required air chute most shingle manufacturers require for shingle warranties.

Each piece can be very easily cut in half using a standard utility knife. The SmartBaffle can be cut in half for double coverage at the eaves area to guard against insulation blockage. Each cut piece would be 18.5” in length.

The SmartBaffle can be installed with a bent down starter to seal the soffit insulation as a weather barrier by simply scoring the two side flanges and bending down at the appropriate distance. What’s more is that the SmartBaffle can be installed from the roof or from the inside room or attic. As you can see the SmartBaffle is very versatile and cost effective.

• More air at the soffit


There were many things I liked about the SmartBaffle product. The first thing was the ease, and simplicity of the installation process. The SmartBaffle is very rigid and firm, and that allows for easy sliding up or down the rafter spaces without the possibility of any ripping or tearing along the way. The second is the functionality of the SmartBaffle. It provides a full 2 inches of airspace, and spans the entire width of the rafter, providing more airspace than any other product I’ve used. The third and overall greatest benefit is that the SmartBaffle can be installed from either the exterior or interior of the attic. If the roof decking is being replaced, it can easily be secured from the exterior of the home, and if not…the rigid SmartBaffle can be pushed up, or down the rafter space for easy installation. I would highly recommend the SmartBaffle to anyone because of these reasons.
