Sika-Trocal S Mechanically Fastened Roof System S-Vap 5000E SA

Homogeneous PVC waterproof membrane for use on mechanically fastened roofs.

System includes:

• Sika-Trocal® S waterproof membrane.

• Polyisocyanurate foam board insulation.

• S-Vap 5000E SA vapour control layer.

Waterproof membrane:

A homogeneous PVC membrane, without any polyester fabric carriers, 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 absence of carrier within the membrane enables the natural flexibility and extensibility of the membrane to absorb any movement of the roof. The membrane also absorbs some of the dynamic wind loads applied to the roof, so reducing the loads transferred to the fasteners.

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.

Vapour control layer:

A 0.60 mm thick, high-performance, self-adhesive vapour control layer, made of 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. Water vapour resistance: >9000 MNs/g.

Can be used as a temporary waterproof layer for up to 4 weeks, in strict accordance with the product data sheet.
