BreaSmart AD is a high-performance exterior house wrap that provides continuous protection against wind, water, and moisture while allowing walls to breathe and dry efficiently. Lightweight, durable, and UV-stable, it helps prevent mold, rot, and energy loss, ensuring long-term wall protection. Its self-adhesive backing bonds directly to the wall surface, creating a tighter seal around seams, penetrations, and corners. This reduces the risk of air and water infiltration, simplifies installation in windy conditions, and enhances overall wall airtightness. BreaSmart AD can be applied directly to clean, dry wall sheathing, including wood, OSB, or plywood. It can be used under siding, brick, or stucco to provide a continuous air and water barrier.
