ce-isoqarPowerlon Metalix is a multilayer breathable membrane with a three dimensional top layer. It is specifically suitable for metal, zinc and copper roofs that can get very warm.

Metalix SA prevents moisture being built up against the bottom side of the roof cladding. The three-dimensional layer ensures that the roof cladding can move in the event of temperature fluctuations. It also reduces the sound coming from rain and hail hitting the metal roof.

The membrane has a base layer to which a spiral layer of polypropylene mesh is melt bonded. It is specially designed as a moisture and separation layer for all types of standing seam and metal roofs, and incorporates self-adhesive edge strips.

Powerlon Metalix has CE Marking for "Flexible sheets for waterproofing – Underlays for discontinuous roofs (EN 13859-1:2010) and walls (EN 13859-2: 2010)"

Industrial Textiles & Plastics Ltd is ISOQAR Quality Assured and certified to ISO 9001.
