PVC
Single ply is a flat, synthetic polymer based roofing material that, as the name suggests, provides a waterproofing layer in a single sheet. Sealed at the joints with heat, adhesive or mechanical means, it can be adhered, mechanically fixed and/or ballasted into flat roof systems.
Single ply roofs are lightweight, flexible, cost effective, swift to install and safe, which makes them increasingly popular for both new build and refurbishment projects.
