PVC membranes around the world enjoy special popularity. They are used for a waterproofing of a roof, the bases, etc. The modern roof of PVC membrane perfectly protects buildings from influences of external environment, at the same time the membrane roof is easy in laying and manages rather cheap.
At construction and new buildings in the USA, Canada and Europe PVC roofs are not casually applied. The roofing membrane is 40-60% more durable than soft bituminous and is only 20-30% more expensive.
The roof of PVC membrane has all advantages of membranes: high permeability and flexibility. For increase of durability of material on a puncture, the roofing membrane is reinforced by a polyester grid. Besides, material easily keeps within even on a rough basis that is connected with reliability of a welded seam of PVC roof and its high deformation ability.
Make PVC roof of qualitative elastic polyvinylchloride (PVC-P). Now release of membranes with various characteristics is adjusted that does this product especially demanded - it can be applied practically in any conditions.
If to compare PVC roof to popular roofs from bituminous materials, then on the physical and chemical to indicators membrane roofs are won, certainly.
First, the membrane roof possesses resistance to any kinds of radiations, and also to thermal aging. Also PVC the roof is steady against wind loadings and is not afraid of oxidation.
Secondly, a membrane roof - more flexible, strong and elastic material. These qualities strengthens reliable welded seams on a joint of cloths. As a result of PVC membrane it is capable to be extended three times. Therefore even at very big differences of temperatures or motions of buildings it will keep all the qualities.
Thirdly, the roofing membrane has also higher rate of fire-prevention firmness
