Product Description

Brentwood’s AccuBlock Unvented Attic Insulation Baffle is specifically designed for unventilated attic spaces, providing an effective seal between the top plate and roof sheathing, where attic insulation is most vulnerable. This baffle system offers a simple, cost-effective solution for architects, builders, and renovators to maintain proper insulation performance, ensuring improved energy efficiency and better indoor air quality.

AccuBlock serves as a spray template at the top plate, creating an efficient barrier that can adapt to any roof pitch or truss size. It is primarily used in spray foam applications, where the top area of the attic is sealed to recreate an unventilated space. The AccuBlock baffle helps optimize insulation performance by ensuring that spray foam adheres effectively in hard-to-reach areas.

Made from 100% recycled, flame-retardant PVC, AccuBlock baffles are quick and easy to install with just a few staples, making them a reliable and practical choice for spray foam installations. While unvented attics are still allowed in certain circumstances, they are becoming less common due to concerns over internal heat buildup that may damage asphalt shingles.

Each baffle measures 22.5" wide by 24.5" long and sits 1.5" deep once installed. It provides 22.5 square inches of airflow, making it easy to seal off attic spaces effectively, especially when using spray foam insulation.
