PVC waterproof system with glass fibre reinforcement for mechanically fastened applications.
A PVC waterproof system which uses a membrane with glass fibre reinforcement, for use in mechanically fastened timber deck roof systems.
- Lower protection layer:
A 300 g/m² polypropylene fleece used either as a protective layer below the waterproof liner or as a protective layer on top of the liner. UV stabilised S-Felt Type T can be left exposed to weathering.
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:
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 usually restrained by the weight of ballast, however under timber decking additional restraint such as Sika-Trocal metal discs or proprietary pressure plates are required.
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 PVC membranes only. Not suitable for high humidity applications or under green roofs.
