Currently works on the renovation of the hotel building are coming to an end, the reconstruction of the roof of 3 700 m² by applying the modern waterproofing material PLASTFOIL® is finished. The PVC membrane PLASTFOIL® ECO 1.5 mm applied for this project has a high resistance to the environmental factors: wind, precipitation, low and high temperatures. The top layer of the waterproofing material PLASTFOIL® has a light color. This fact allows it to reflect UV radiation and realize the concept of a cool roof (energy-saving roofing system), as contrasted with bituminous materials of black color. Realizing of the mentioned concept is very important for the objects of the southern region. Biostable waterproofing membrane PLASTFOIL® is resistant to oxidation, appearance and development of mold. Comfortable and fast installation is performed mechanically without the use of gas cylinders and open flame which fully meets the requirements of an increased security during the roofing works. Rolls of the waterproofing membrane PLASTFOIL® have a large area - the width is 2.1 m, the length is 20 m - this reduces the number of weld seams, the main places of leakages. The weight of the membrane PLASTFOIL® is 3-4 times less than the weight of bituminous materials, which helps to reduce the load on the entire roof structure. Durable coating PLASTFOIL® allows solving successfully the problems of effective protection of any real estate units from the negative environmental factors.
