Flat Roof Breather Membrane

Specially formulated flat roofing products.
Flat roof breather membrane. The location of the roof its pitch baton gauge and the tile used are all important considerations and the best breathable roof membrane for one project may be poorly suited to another. Breather membrane relates to membranes used in timber frame walls with a vapour resistance of 0 6mns g or less while for those membranes used on roofs the term vapour permeable underlay is more appropriate these membranes must have a vapour resistance of 0 25mns g or lower. Breather membranes or breathable membranes can be used to keep the internal components of wall and roof structures dry. To combat this loss ybs have specially manufactured flat roof insulation certified to industry standards.
Breather membranes otherwise known as breathable membranes are used within external wall and roof constructions in order to prevent damp in buildings. High quality breather membranes help to reduce heat loss across the entire roofing system whether pitched or flat domestic or commercial. Whether you are looking for insulation to fit between the joists or under the joists ybs insulation offers a product to suit your needs. They work by allowing insulated structures to easily release excess moisture vapour into the atmosphere.
Tyvek supro is the market leading breather membrane and is a water resistant membrane suitable for all supported and unsupported pitched roof applications in commercial and residential buildings. Bs5250 clause 8 4 1 1 3 recognises two types of underlay with breather membranes being defined as type lr breathable underlay has a water vapour resistance of less than or equal to 0 25mns g. Flat roofs have low or no gradient and are a huge area of heat loss for buildings. The good news is that we don t have to take a stab in the dark when it comes to selecting the right waterproof membrane.
