Air Permeable Breather Membranes

Breathable membranes, also known as air permeable breather membranes, are a type of building product used in construction. These membranes are designed to allow moisture vapor to pass through while preventing the entry of liquid water. They are typically used in walls, roofs, and floors to improve the overall energy efficiency and moisture management of a building.

Breathable membranes are made from materials that are both water-resistant and breathable, such as microporous polyethylene or polypropylene. They are installed on the exterior side of insulation, acting as a protective layer against wind, rain, and condensation. By allowing moisture to escape, these membranes help prevent the buildup of mold, rot, and other moisture-related issues within the building envelope.

These membranes are available in various thicknesses and strengths to suit different construction applications. They are often used in conjunction with other building materials, such as insulation boards or timber frame systems. Breathable membranes are a popular choice for both new construction and renovation projects, as they offer improved thermal performance, air quality, and durability.

Overall, breathable membranes play a crucial role in creating a well-insulated and moisture-controlled building envelope, contributing to the overall comfort, energy efficiency, and longevity of a structure.
