Thermofol U15 FB Membrane

Thermofol U15 Fleece-Backed Membrane is a 1.5mm polyester reinforced Poly Vinyl Chloride membrane (PVC) with 1mm polyester fleece laminated to the underside.

This membrane is primarily used in an adhered installation and can be bonded directly to aged bitumen. The pre-coated cross weave polyester reinforcement facilitates high levels of tear resistance.

This product benefits from being flexible with high tensile strength, good thermal stability, chemical resistance due to the inclusion of internal plasticizers during the manufacturing process.
