Technoelast Enviro Air K-PS 170/5000

A torch-applied, bituminous cap sheet, which is saturated and coated with high quality styrene-butadiene-styrene (SBS) modified bitumen. It has a tough polyester reinforcement, polyethylene film on the underside and features a hydrophobized slate surface on the top surface, which is covered with titanium dioxide (TiO2) and special additives.

The specially modified slate surface functions as a catalyst in the process of changing harmful nitrogen oxides (NOx) into harmless levels of nitrates. The process is activated when ultraviolet radiation from the sun hits the titanium dioxide particles, releasing energy for breaking down the NOx particles. Polluted air passes over the membrane where the NOx is converted into harmless levels of water, carbon dioxide and nitrates, which are washed away by the rainwater. The special coating also contributes to the destruction of organic contaminants on the surface of the roof, such as bird droppings, fungus spores and bacteria.

Features and benefits:

• High quality torch-on cap sheet.

• SBS polymer modified bitumen.

• Low temperature flexibility at -25°C.

• Suitable for use as part of a torch-safe or full torch-on system.

• Innovative air purification properties.

• CE marked.

Applications:

Designed for use as a high performance cap sheet, and can be used as the final waterproofing layer on a variety of TechnoNICOL built-up roofing systems (e.g. Torch-Safe and full Torch-On specifications). The membrane is compatible with all common bituminous underlay membranes and also provides innovative air purification technology.
