Product Description
Brentwood’s AccuBlock Unvented Attic Insulation Baffle is specifically engineered for unventilated attic spaces, providing a tight seal between the top plate and roof sheathing—exactly where attic insulation is most vulnerable to air leakage and energy loss. This solution is ideal for spray foam applications where the attic is sealed off to create a conditioned, unvented space.
This baffle acts as a spray foam template, guiding the foam application and helping ensure complete coverage at the top plate. It’s designed to adapt easily to any roof pitch or truss configuration and can be installed in just minutes using a few staples. Made from 100% recycled, flame-retardant PVC, AccuBlock is both durable and compatible with all common insulation types—though it's primarily used in spray foam systems for unvented attic assemblies.
While unvented attics are still allowed in certain jurisdictions, this approach is becoming less common as some asphalt shingle manufacturers express concerns over potential heat buildup that may affect roofing materials. Always check code compliance and manufacturer recommendations before installation.
Each baffle measures 14.5" wide by 24.5" long and sits 1.5" deep once installed. It’s used to seal the area between the wall and roof in unvented attics—especially helpful when applying spray foam insulation to create a sealed, energy-efficient space.
