Roof Breather Membrane

Often without the need for ventilation.

Roof breather membrane.

Breathable membranes or breather membranes have been designed to improve ventilation and reduce condensation build up within the roof space as well as ensuring insulation remains effective. Breather membranes or breathable membranes can be used to keep the internal components of wall and roof structures dry. Vapour permeable breather membranes protect against wind insects dirt weather penetration whilst insulating your property. 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.

Installed to the outer side of the insulation over or under the counter battens on a pitched roof breather membranes allow water vapour to escape from inside a building. On roof valleys ensure the breather membrane is extended by a minimum of 300mm on each side measured from the centre of the valley. Breather membranes otherwise known as breathable membranes are used within external wall and roof constructions in order to prevent damp in buildings. Breather membranes were designed as an alternative to tile vents breather membranes allow ventilation to occur and water vapour to pass through removing the need to install a number of tile vents along the roof saving time money and labour.

Why breather membranes are required moisture often passes into the roof space as vapour and then condenses when it reaches a cool surface.

Although it can be made air permeable to some degree high resistance membrane is only suitable for use in cold ventilated pitched roof systems. Roof breather membrane on the other hand allows far greater moisture transfer making it crucial that there is adequate air movement above.
