Travis Brungardt and Jake Boyer discuss a cutting-edge approach to interior air sealing, especially for challenging retrofits like older brick facades. Jake, a VP at Prosoco, introduces a new product called *Targeted Interior Air Seal*—a fluid-applied sealant designed for ease of use and effectiveness. They explain its advantages over traditional membranes, particularly when preserving exterior aesthetics is critical. The product fills gaps efficiently without tooling and is ideal for inaccessible or irregular surfaces. The discussion highlights how this method supports long-term durability, enables interior drying, and complements Prosoco's CAT5 system to enhance building performance from the inside out.
