Epiclad FBS (EPDM Fleece-Backed System) Rubber Waterproofing Membrane
Description

Viking Epiclad FBS (fleece-backed system) is a roofing membrane where a 'fluffy' polyester layer is factory-laminated to the underside of the Viking Epiclad waterproofing membrane. Epiclad FBS is one of the best re-roofing solutions for overlaying over old bitumen or uneven substrates such as rough concrete. A specialised two-part foam adhesive is used to securely bond the membrane to the old roof, and the fleeced underside forgives its roughness; thus creating a lot smoother surface than before.

Epiclad FBS also saves labour time in up-lifting the existing membrane; avoids the environmental impact of waste disposal of the uplifted roofing materials; and minimises the disruption to building inhabitants who don’t have to be relocated.
