Breasa
Breathable Air & Water Protection for Wall Assemblies
Breasa is a breathable building envelope membrane designed to protect wall assemblies from wind, water, and moisture intrusion while allowing water vapor to escape and walls to dry naturally. Its tear-resistant, UV-stable construction provides dependable durability during installation and exterior construction, helping manage moisture and air movement within the building envelope.
Lightweight and easy to install, Breasa helps contractors work efficiently while providing reliable wall protection. Suitable for use behind siding, brick, stucco, and other exterior cladding systems, Breasa functions as an effective air and water barrier while supporting proper moisture management within the wall assembly.
Key Advantages:
- Breathable Moisture Protection – Helps block bulk water intrusion while allowing water vapor to escape and wall assemblies to dry.
- Durable, Tear-Resistant Construction – Designed to withstand handling and installation demands on the jobsite.
- Air Barrier Performance – Helps reduce uncontrolled air movement, drafts, and associated energy loss within the wall assembly.
- Lightweight & Easy to Install – Easy to handle and install, helping contractors maintain efficient construction.
- UV-Stable Construction – Provides reliable temporary protection during exterior work and before final cladding is installed.
- Versatile Cladding Compatibility – Suitable for use behind siding, brick, stucco, and other exterior cladding systems.
