Vapour control layer.

Application

Torch applied membrane suitable for use as a vapour control layer in bituminous, single-ply or liquid roof waterproofing systems (warm roof). The membrane is used beneath insulation and safely controls the passage of internal water vapour through the roof structure. Since the membrane adheres, it can provide a weatherproof temporary finish to the roof structure prior to the application of the final waterproofing system. It is suitable for use on both new and refurbishment projects.

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 these membranes.

The timber used in the construction of the roof deck must not be treated with solvent-based preservatives.

Description

An SBS-modified bituminous membrane reinforced with an extra strong glass fibre fleece with aPET film. The upper surface is finished with specially formulated low melt bitumen stripes with a silica sand coating between and has a selvedge of 75 mm and is then finished with a thermofusible film. The lower surface is finished with a thermofusible film to prevent sticking in the roll.

Features and benefits:

  • Impervious to water.
  • Unaffected by freeze/ thaw cycling. It will support temperatures from -20 to +90 °C without damage.
  • Correctly installed the product will have a life at least as long as that of the overlying roof waterproofing system.
  • The membrane is compatible with most building materials with which they are likely to come into contact with during roofing works.
  • CE marked (EN 13970, 13, 0086).
