Sika-Trocal SG

A PVC membrane, with glass fibre reinforcement, for use in mechanically fastened single-ply waterproof systems. Highly resistant to ageing and industrial pollutants and requiring no surface treatment or maintenance throughout its service life.

The glass fibre reinforcement virtually eliminates shrinkage, which makes the membrane suitable for use on concave roof surfaces with a radius of less than 20 m.

The membrane is fastened with Sika-Trocal metal discs or proprietary pressure plates, secured with thermally broken fasteners.

Laps are sealed with THF welding agent, with hot air sealing used at details.
