The membrane is intended for redevelopment of old asphalt ply coverings of flat roofs, additional thermal insulation of the ply without a possibility of ballasting or mechanical anchoring, waterproofing of shelters or lighter constructions. The lower side of the membrane, which is furnished with a textile pad, is suitable for the contact with bitumens.
PVC (polyvinylchloride) is a universal, proven, and reliable material. It was developed in the thirties of the 20th century as one of the first synthetic materials – plastics. It is a material well workable using various technologies, e.g. rolling, extrusion, depositing, or casting, therefore it is predestined for wide range of applications.
PVC has a unique combination of features, which can be further modified in various ways using processing additives. PVC is usually classified into softened - called most frequently PVC-P, ands hard - called PVC-U. Polyvinylchloride ranks among materials that can be recycled well and reused in the manufacture of products. Recyclable PVC is marked PVC-R. In general, products from PVC are called vinyl products.
PVC-P is suitable especially for applications where flexibility and elasticity are essential. Main fields of softened PVC’s application include:
Subjects of common use – raincoats, inflatable toys, table cloths, janitorial gloves.
Building industry – insulation foils, e.g. swimming pool insulation, ground and roof insulation, green roofs, flooring of various types in rolls and tiles, soft profiles and baseboards, wallpapers.
Automotive and electrical industry – most commonly cable sheathing.
Health care – blood pocket bags, medical tubes and hoses.
Other industries – promotional items, billboards, packages.
PVC-P features are modified with respect to particular application. Where the appearance is important, the frequent requirement is to achieve the specific colour shade, multi-colour print, or to create a design on the product surface (wood or leather imitation). In technical applications, the most frequent requirements are the long service life and durability. Using the right additives, the service life may reach 10, 15 years, or even more.
Membranes may only be installed by qualified and specially trained contractors. Membranes must be installed in accordance with guideline FATRAFOL-S.
