First of all the quality of the polycarbonate acquired by you, both monolithic, and cellular, has to be certified by the corresponding certificate. As this material is required to you for arrangement of the greenhouse on the seasonal dacha, most likely you will order cheaper polycarbonate – cellular transparent.
The first question which at the same time arises – what it has to be thickness? Here it is necessary to consider the pressure force of wind and snow on future design if in it there are curvilinear surfaces – that with what bend radius, the frequency of furring at which polycarbonate sheets will be mounted.
Remember that the leaf is thinner, the more often there has to be furring and vice versa. the leaf is thinner, the more often there has to be furring.
The quality of cellular polycarbonate can be checked on its weight. According to the global standards, there is such dependence of weight of polycarbonate leaf of 1 sq.m. on its thickness: four-millimetric – 0.8 kg, six-millimetric – 1.3 kg, eight-millimetric – 1.5 kg, centimetric – 1 kg 700 grams. When weight parameters of the material acquired by you corresponds to these digits, it is possible to count that polycarbonate will successfully transfer also the mechanical loading declared producers, and will sustain the guaranteed ten-year term of its operation without replacement.
For construction of some designs less strong sheets of cellular polycarbonate of the facilitated type can be used. However such products should be with distinctive marking, the Makrolon V-line type, but not just Makrolon, or – Carboglass Light, Polylight, and in the certificate of quality it has to be noted that they have five-year guarantee period.
The following question – about coloring of the chosen material which choice depends not only on your whims, but also on the fact that you are going to build of cellular polycarbonate. Hotbed or greenhouse? Then polycarbonate cellular transparent is necessary, but here under canopy from such material to you it will be hardly comfortable. The turquoise, green or blue polycarbonate sheet will perfectly underline beauty of your pool, but is not suitable for greenhouses at all.
Trademarks of the well-known European and Israeli companies making polycarbonate plates do not give guarantee of appropriate quality and authenticity of material yet – it can quite be the Chinese fake. On original polycarbonate by all means there is the thinnest layer of protection against UV-radiation put in the extrusive way. Availability at the seller not only polycarbonate plates, but also spare parts, necessary for their mounting, from the same producer – tapes edge, profiles, thermal washers and other can also be the proof of quality and authenticity of the acquired material.
