PVC waterproof membrane with glass fibre reinforcement for ballasted applications.
PVC waterproof system for ballasted roofs.
- Upper protective layer:
S-Felt T 300:
A separation, levelling and protection layer made of polyester (PES).
- Sika-Trocal® SBV:
A protection and separation layer made of polyester (PES) fleece with a PVC-P coating on one side. The fleece free edge is 5-15 mm wide.
- Waterproof membrane:
A PVC membrane, with glass fibre reinforcement, for use in ballasted single-ply waterproof systems. The membrane contains biocides and is highly resistant to ageing, to industrial pollutants and to the bacteria that flourish in the moist layer of dirt present immediately above the membrane in ballasted roofs. It requires no maintenance throughout its service life.
The membrane is restrained by the weight of ballast, although under timber decking additional restraint such as Sika-Trocal metal discs or proprietary pressure plates may be required.
Laps are sealed with THF welding agent, with hot air sealing used at details.
- Vapour control layer:
A 0.60 mm thick, high-performance, self-adhesive vapour control layer, manufactured from polymer modified bitumen, with glass fibre reinforcement and aluminium foil top layer. Suitable for use in high humidity environments, green roofing systems, loose-laid ballasted warm roof systems and all adhered and mechanically fastened systems. Can be used as a temporary waterproof layer for up to 4 weeks, in strict accordance with the product data sheet.
