Tyvek® is a wondrous material from the textile giant, DuPont®. Made from high-density polyethylene fibres, Tyvek® allows water vapor to pass through it but not liquid water, meaning it is an excellent choice for a roof breather membrane. Tyvek® protects buildings against condensation, water and the outside elements and is extremely durable. This tough polyethylene membrane is tear resistant yet easily cut to size with a knife or scissors, meaning it is easily installed in a variety of situations and applications. A quality breather membrane not only protects from moisture but also improves the energy efficiency of a property. Products in the Tyvek®range have been specifically designed to improve insulation and cut down on your energy bills. Below are the key product lines in the Tyvek® range.
