Application

Suitable for use as a vapour control layer in a warm roof system build-up.

Hydrocarbon solvent-based products, such as Naphtha, paraffin and creosote will have a harmful effect and should not be allowed to come into contact with the material.

Description

TorchSafe T.A. VCL - Stripes is a glass reinforced styrene-butadiene-styrene (SBS) modified bitumen membrane with special bitumen bonding stripes on the upper surface.

Features and benefits:

The material is compatible with all materials normally used in roofing structures and finishes and may be cut and formed using techniques described in BS 8217:2005. There are no harmful side effects associated with this material.

Applications:

Suitable for use as a vapour control layer in a warm roof system build-up.

Hydrocarbon solvent-based products, such as Naphtha, paraffin and creosote will have a harmful effect and should not be allowed to come into contact with the material.
