Metal roofs are becoming increasingly popular, on both residential and public buildings, under different climatic conditions. Since the mid-1990s, structural ventilation layers have been used to ensure that entrapped moisture between the metal roof and substructure can diffuse and to allow for sufficient air circulation. The first underslating/ drainage composite layers have been developed by Colbond in cooperation with zinc roof supplier Rheinzink, Germany.

Ensuring adequate ventilation and drainage, these spacers help to significantly extend the service life of the entire roof structure. The installation of such layers is not only recommended by the installers and industry associations, but it is often required by building regulations. Furthermore, many leading metal roof manufacturers will only issue a guarantee for their roofing product, if an approved venting layer is used.

In addition to their ventilation and drainage functions, the three-dimensional ventilation layers also play a major role in terms of building acoustics, reducing the rain fall noise by more than 50%.

Roofers throughout Europe are increasingly turning to Colbond's Enka^®-Vent as their product of choice. For additional information on Enka-Vent, please visit our website on building products at www.colbond-building.com.
