Hydro-insulation of flat roofs

A roof with an effective, thoroughly designed hydro-insulation system, including details, is one of the most important parts of a building. It requires not only high-quality hydro-insulation material but also necessary auxiliary elements. Plastic coated Viplanyl sheet, the main field of utilization of which are termination and fixation sheet elements for applications of PVC hydro-insulation foils, represents one such auxiliary element.
Processing a plastic coated Viplanyl sheet is similar to processing sheets without a PVC layer with the difference consisting in the fact that sheets cannot be joined by soldering or welding. Joining is possible by overlapping (roof formats), riveting and joint sealing with a permanently elastic bonding agent. The PVC layer does not require any other surface finish with paints. If it is required (change of colour), it can be painted with synthetic or dispersion paints (type and kind of paint used should be consulted with the sheet manufacturer beforehand). The PVC layer must be protected against the effects of organic solvents and compounds, otherwise the chemical inertness with respect to softened PVC is not guaranteed.
Sheets are not intended for use in contact with drinking water and foodstuffs. If not stated otherwise, sheets or the PVC layer is not suitable for contact with materials on the basis of bitumen, asphalt and tar.
Handling, applying and joining can be performed under temperatures from -5 °C to +40 °C in dependence upon joining method.

VIPLANYL characteristics

VIPLANYL is a composite material consisting of a metallic substrate and an organic coating, which in itself associates excellent properties of both above mentioned materials. A protective layer made of organic material provides the product with excellent protection against corrosion; it is endowed with good workability and can be made in many different colours so that it is also possible to achieve a highly decorative effect.
