Description and Scope: The pvc membranes are a group of polymeric roofing waterproofing materials based on pvc. They are suitable for both new construction and for work on reconstruction and capital repair of public buildings, industrial and residential assets. Materials suitable for the majority of roofs: flat, inclined or curved – and can be installed on foundations of wood, tin, lung and conventional concrete. PVC-coating and thermal insulation attached special mechanical fasteners at the edges, to the platform. The number of these fixtures and the type of applied pvc coatings affect building location, design roof and its shape and wind loads. Laying: welded seams automatic welding machine with hot air, with the attachment remain under cover.
Small and difficult parts of the roof welded hand equipment. pvc membranes are composed of three main components that together create a strong homogeneous material: flexible pvc slip surface, polyester, pvc components, painted in gray. Advantages: – Adaptability to the roofs of any structures – Resistant to uv radiation – Good appearance – usually up to 9 colors – Lightweight – at a thickness of 1.2 mm in density up to 1,4 kg / sq.m. – Independent Mounting weather conditions (rain, snow, subzero temperatures), the temperature of use from -50 C to +80 C – fire safety during installation (use hot air welding) – high speed of installation – up to 500 square meters. m per shift. Disadvantages: – For application material must additionally be trained professionals – The high cost of equipment. – Instability of bituminous materials, oils and solvents. Lifetime: 25 years and more.
