Not all Breathers are the same

There are a number of breather membranes on the market and the designer must consider a number of issues when deciding which breather membrane should be used. Roofshield is the result of many years' research in providing the latest technology in non woven fabrics.

Roofshield is a three layer laminate designed to combine water hold out properties with high breathability. The central layer is a fine-fibred meltblown material which differs from other breather membranes on the market. This unique central layer provides a fibrous structure which allows for a much higher breathability than other laminates which may include films. These small fibres give increased water hold out over spunbond single layer products and afford a number of advantages which are listed below.
