Backed by three decades of experience, Alwitra's Evalon single-ply roofing offers high levels of long-term waterproofing protection. The EVA-Terpolymer-based membrane is of homogenous construction, rather than in layers, and its lack of volatile plasticisers means it will not migrate even under extremes of temperature. Evalon is bitumen-compatible, and so can be installed directly over a failed roof surface.
