Polycarbonate sheet products are widely used both on an industrial scale and "in the home".This synthetic polymer has many advantages that favorably distinguish it against the background of various building and finishing materials. Its lightness, strength and non-adherence to the influence of the environment make it universal in application.
Covering roofs, arranging a variety of fences, partitions, awnings is not a complete list of where polycarbonate can be used. But the given production has a number of features, including, "honeycomb" structure. This also determines the specificity of fixing the sheets in the place of installation. For their fastening traditional fasteners - nails, self-tapping screws - are not suitable. In case of their application there is a risk of destruction of the integrity of the cells( "honeycombs"), which entails deterioration of such qualities of the material as heat, sound and waterproofing.
The fixing "part" for carbonate consists of 2 parts - a self-tapping screw and a special gasket( thermowashing), which simultaneously plays the role of both shock absorber, sealant and sheet surface protection against damage. This fastening, given the features of polycarbonate, has undeniable advantages.
Firstly , the appearance of "cold bridges" is excluded. This happens always when materials with different degrees of thermal conductivity are held together. In this case, the sheets are made of polymer, and the screws are made of metal. This is especially important for buildings in which the maintenance of the temperature regime is given increased attention. For example, a greenhouse, a greenhouse.
Secondly , ease of work with fasteners. It's no secret that not everyone will be able to properly score a normal nail, or strictly vertically, without distortions, wrap the screw. Mounting with self-tapping screws for polycarbonate does not require any experience and, moreover, training. The tip of the working part is executed in the form of a drill and easily enters into any base.
Thirdly, , ensures the guaranteed lifetime of polycarbonate. It is the presence of a special washer that excludes the deformation of the sheets at the point of fixation as a result of thermal influences( thermal expansion due to temperature drops).
Fourth , high-quality insulation of the attachment point. This is especially important when installing the sheets horizontally, when there is a risk of leakage in the locations of the fasteners.
The thermoshow is available in 2 versions - flat and with foot. The first one is used for fastening thin sheets, and the second one is used for thicker sheets. The "foot" is embedded in the material and provides insulation and protection of the "shear" from deformation during operation. In this case, a hole of the appropriate diameter is drilled in the sheet. The original latch allows not only to increase the reliability of fixing, but also provides additional isolation of the mounting location of the fastening element.
Screws of the main sizes stand in the range of 3.5 - 5 rubles / pcs."Normal" washer 7 - 8 rubles, "thermo" - about 10 rubles / piece.
