Application

For use in mechanically fastened timber deck finished roof systems.

Description

A PVC waterproof system which uses a membrane with glass fibre reinforcement for use in mechanically fastened timber deck roof systems.


System:

  • Timber decking surface protection.
  • S-Felt T 300 or Sika-Trocal® SBV upper Protection Layer above SGmA membrane.
  • Sika-Trocal® SGmA waterproof membrane.
  • Sikatherm® PIR AL insulation.
  • S-Vap 500E vapour control layer.


Upper Protection Layer:

S-Felt 300:

  • 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.

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:

The membrane contains biocides and is highly resistant to ageing, industrial pollutants and the bacteria that flourish in the moist layer of dirt 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, low density polyethylene 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.
