The roof of a building should be water resistant and water resistant, cold-and heat-resistant and durable to withstand snow and wind loads and mechanical stress while cleaning snow from the roof, and during the repair. The technology of roofing work, and their complexity depends mainly on the materials used. They can be rolled, mastic, foil and piece. The easiest way (and cheaper) to cover the roof of a flexible roll roofing. True, traditional roofing and roofing are not very durable and require repair after a couple of years. The latest technologies allow a flexible sheet flooring easy installation and at the same time very robust. One of these roofing materials is Technoelast. Due to the use of a synthetic polymer (polyester) or glass (fiberglass), Technoelast provides unparalleled strength and elasticity. Its basis is impregnated with a mixture of unoxidized asphalt, modifications of synthetic rubber and mineral filler. There are several brands Technoelast (Table 1). Marc material weight 1m2, KG Type foundation type of surface coverage, up / down method of laying Roll Size (length width), m EKV6, 0 "Vent" 6.0 Polyester, no less than 250 g / m * Thick broadcast with / "vented" cover fusing / fixing 7,5 x1, 0 EX 5,0 5,0 Polyester, not less than 170 g/m2 Thick broadcast with / self-adhesive Self-adhesive coating (cold gluing) 10x1, EKP5 0, 0 5.0 Polyester, not less than 170 g/m2 broadcast with coarse / film fusing 10x1, 0 TKP5.0 5.0 Polyester, not less than 200g/m2 Thick broadcast with / film fusing 10x1, EPP4 0, 0 4.0 Polyester, not less than 170 g/m2 film / film fusing / fixing 10x1 , 0 HPPZ, 0 3.0 Fiberglass, not less than 60 g/m2 film / film fusing 15x1, 0 In the manufacturing process Technoelast formed elastic polymer-bitumen composition to withstand wide temperature range and resistant to cyclic deformation during many years of operation ( Table 2.). Table 2. Basic physical and mechanical characteristics of roofing Technoelast type of polymer modifier SBS Flexibility on a bar radius of 10 mm, not above -25 ° C Softening Point (Kish) 110 ~ 115 ° C dry heat for 2 hours on a vertical surface, not below +100 ° C Approximate Breaking Load, N kg / cm for materials on the basis of: fiberglass (200 g/m2) 780 polyester (150 g/m2) 670 water permeability at a pressure of 0,2 MPa (20 m water column) for 2 hours, no water permeability at a pressure 0.01 MPa for 72 hours there each brand of roofing material has its own area of ??application (Table 3). Material grade lower layer roof membrane top layer of roof membrane roofing and waterproofing Sites Waterproofing basements Waterproofing transport facilities ECP EPP EMP HSP + + + + + + + + This allows you to choose exactly the brand that is best suited to specific conditions. Technoelast is highly resistant to aggressive environments. Sediments that contain chemically active substances, man-made water and saline soils are not afraid of this material. It does not destroy neither acid nor chloride and sulfate. It is known that the largest number of defects in roofing and waterproofing is provided in places of its adjacency to the elements of the building. When using Technoelast due to its strength and flexibility, these problems do not arise. According to the laboratory TSNIIPROMZDANY life of the roof of this material - at least 25 ... 30 years. Before laying the roof of Technoelast the ground surface is cleaned of dirt, dust and soil bitumen primer. For double-layer "breathable" roof membrane as the first layer using roll roofing material - Technoelast ECV 6.0 "Vent" on the bottom surface of which there are air channels to drain water vapor. Particular attention should be paid during installation of fusing overlap and the installation of ventilation funnels lower breathable layer. Technoelast overlay using a propane torch, gas which is fed from a standard tank through a reducer. To trim and roofing material will need a knife. On the roof of a small area you can work with a blowtorch. Burner flame melted the protective film and a bottom layer of binder composition. Polymer film, which covered the lower surface of the material has a special pattern on melting which is easy to determine the readiness Technoelast to gluing. In the process it is important to remember the fire-up and compliance with safety regulations.
