PVC waterproof system for warm roofs.
- Waterproof membrane:
A PVC membrane, with glass fibre reinforcement and a fleece backing to the underside, for use in adhered single-ply waterproof systems. Suitable for pitched, flat and curved roofs. Highly resistant to ageing and industrial pollutants and requiring no surface treatment or maintenance throughout its service life.
The membrane is designed to be fully adhered to suitable substrates using Sika C300 polyurethane adhesive.
Laps are sealed with THF welding agent, with hot air sealing used at details.
- Vapour control layer:
A 0.15 mm thick, polyethylene based, vapour control layer. S-Vap 500E is manufactured from low density polyethylene, blended to produce a vapour control layer that is flexible when cold, resistant to chemicals and ageing and rot proof. It is suitable for use in most mechanically fastened systems using the Sika-Trocal membranes. Not suitable for high humidity applications or under green roofs.
