Installed with minimum fuss & disruption

What is the Alwitra Evalon roofing system?

The Alwitra Evalon flat roofing system is a watertight membrane compound which consists of VET (Vinyl Ethylene Acetate Terpolymer) and polyvinylchloride. This plasticiser free, flexible flat roofing membrane offers outstanding waterproofing properties for all flat roofs.

Many flat roofing solutions which include felt and fibre glass solutions, cannot withstand extremes in weather conditions and the materials used can crack due to the change in temperatures. The cracks make the roof vulnerable to wind and rain and water can leak into the cracks causing much damage.

Minimum fuss and disruption, long-lasting results

The Alwitra membrane comes in rolls. It can be laid over existing roofing systems but if there is any damage to the decking then it is advisable to have new materials laid or repairs carried out.
