Total Torch Vapour Dispersion Layer

A glass fibre reinforced SBS modified bituminous membrane. The upper surface is finished with a thermofusible film. The underside surface has specially formulated low melt bitumen stripes with quartz sand between to prevent adhesion during application. The underside is finished with a thermofusible film to prevent sticking in the roll.

Features and benefits:

• Impervious to water.
• CE marked (EN 13707, 13, 0086-CPD-505779).
• Unaffected by freeze/ thaw cycling, will support temperatures from -10 to +90 °C without damage.
• The product used in conjunction with a suitable Icopal SBS capsheet may be expected to last 20 years.
• The material is not susceptible to insect attack or pest damage and is unaffected by fungi, moss, lichen, moulds or bacteria.

Stripe technology:

• When trapped pockets of vapour in the system begin to warm up they expand and can form blisters. The specially formulated striped resinous profiles are optimally spaced to cover 50% of the membrane surface.
• The areas between the striped profiles are coated with a quartz sand mixture toprevent adhesion during application creating resin-free channels.
• The resin-free channels allow any trapped vapour to dissipate along the channels under its own pressure thus preventing blistering.
