Technical Data Sheet

DESCRIPTION

The composite reinforcement, made of nonwoven spunbond polyester in combination with fiberglass, conveys high mechanical characteristics, excellent dimensional stability and elastic performance. Shaping of sheets, straightness, dimensional and surface uniformity are accomplished by hot calendaring of the mass at hot melt fluid state.

The upper surface is coated with thermo-fusible polyolefin film or nonwoven polypropylene and selvedge protected by anti-adhesive removable film for easy welding overlap. The lower surface is protected with a anti-adhesive removable film.

FIELD OF APPLICATION

NOVA-SK is a high-performance membrane. It is particularly suitable as an under layer in multi-layer waterproofing systems, with all membrane types; it is very appropriate where a flame is not allowed for safety reasons.

General roofing, discontinuous roofs, on or under floors or ground slabs, are valid examples of the design application of this product. It is not suitable for roof gardens. It can be applied onto every substrate (concrete, masonry, steel, tension structures, wood, cellular insulation panel, membrane, etc.).

The excellent mechanical characteristics and high level thermo-dynamic stability make it suitable for any climate conditions and all the situations where a barrier against water is required

METHOD OF INSTALLATION

The high self-adhesive properties of the waterproofing compound allow the application without a flame, simply removing the lower anti-adhesive removable film. In particular situations, it could be applied with a hot air generator.

The application of the membrane must be carried out in good weather conditions, when the temperature is over 10°C, and after the substrate has been adequately cleaned and prepared.

PACKING AND STORAGE

The product is packed as standing rolls on wooden pallets wrapped with thermo-shrinking protective hoods. Rolls must be stored in the upright position, without stacking the pallets to avoid deformations which can compromise the correct application of the membrane. The product must be stored indoor, protected from heat and frost.
