IMPERDAN FV 40P

About this product

IMPERDAN FV 40 P (10x1).- is a waterproofing bituminous sheet with non self-protected surface of 4.0 kg/m². Composed of a fibreglass reinforcement and covered on both sides with polymer modified bitumen (pliability -5ºC) mastic. A polyethylene film is used as anti-adherent material on both sides. Tested according to standard EN test methods.

As a slaking layer that serves to increase the mass of the single-ply membranes and improve adhesion to the substrate.

Single-layer waterproofing membrane underlay for waterproofing of roofs with heavy bonded protection.

Improved single-ply waterproofing membrane underlay for waterproofing of heavy non-bonded or floating roofs with heavy protection.

Increases performance on the site.

A better performing membrane than an oxyasphalt membrane of similar characteristics.

Little thermal variation.

Better melting.

As it's made from polymer-modified bitumen mastic and in comparrison to oxyasphalt sheets, the membrane provides, high performance at high and low temperatures, plasticity and resistance to ageing, which leads to a longer durability of the sheet and the safety of the waterproofing membrane.

Limits deformations.

Limits stresses in the waterproofing membrane.

Allows for adaptation to any type of geometry.
