About Single Ply Roofing Membranes

Single-ply roofing consists of an impervious membrane formed by laying and joining strong, flexible sheets to create a continuous waterproof barrier across the surface of a flat roof. The sheets are joined using either heat or are self-sealing and are retained by mechanical fixing, adhesives, ballast, green roofs or paving. The membrane is generally made from a synthetic polymer that has been formulated to resist weathering, chemical oxidation and UV radiation and to retain its physical properties over a wide range of temperatures.

FDT (FlachDach Technologie GmbH – ‘Flat Roof Technology’) is Europe’s leading single-ply roofing membrane manufacturer with manufacturing plants in Mannheim and Hemsbach in Germany. FDT launched Europe’s first single-ply roofing membrane 70 years ago, has since sold more than 200 million m² of membrane and produces Rhepanol, the world’s most advanced single-ply roofing membrane.

Single-ply membranes are available in a variety of materials.
