Flat Roof Breather Membrane

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 roof breather membrane.

Permavent breather membrane utilise the world s leading medical technology to produce the best quality construction breather membrane in the world. They work by allowing insulated structures to easily release excess moisture vapour into the atmosphere. 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. The immediate benefits to this are clear as straightaway the home gains a better energy rating.

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. Specially formulated flat roofing products. Breather membranes otherwise known as breathable membranes are used within external wall and roof constructions in order to prevent damp in buildings.

Flat roofs have low or no gradient and are a huge area of heat loss for buildings. Permavent low pitch slate roof solution ripping up the rule book for low pitch slate. Whether you are looking for insulation to fit between the joists or under the joists ybs insulation offers a product to suit your needs. 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.
