Polyvinyl Chloride, or U-PVC

 PVC is a synthetic thermoplastic polymer. Due to special additives (stabilising, hardening and plasticizing agents), it is used in the construction of door and window frames. Hard PVC conditioning can be grouped into three categories:

•Acrylic Elastomers (A.C.R.)
•Ethylene Vinyl Acetate (E.V.A.)
•Chlorinated Polyethylene (C.P.E.)

 Apart from the core material, PVC, and the conditioning, deoxidised titanium is also added to give the finished product a pure white surface and to increase its resistance to the effects of time. Calcium carbonate, a polish of a particularly thin particle diameter, is also added to minimize the effects of impact.
 Finally, when the composition of the PVC conforms fully to international specifications, and after it is checked by the Technological Institute of Door and Window Frames, the assembly process of the completed synthetic frame begins.
 The PVC profile includes main (framing sheet) and secondary (water, glass triangles, special sealing soles) elements, which aid the formation of completed and perfectly functional door and window frames. A necessary supplement to the proper functioning of a synthetic PVC frame is metallic reinforcement of the case and the movable sheet, something that considerably improves the mechanical durability of the frame above 80 °C. Of course, the final reinforcement should not be randomly created. It is necessary to fulfil the durability conditions in the case of rust and temperatures reaching 315 °C.
 An important aspect of sound and heat isolation that we demand from the synthetic framing is the air space between the glass sheets. The air space is determined by each manufacturer's profile.
For aluminium door and window frames with 4-mm double-glazed windows and a 15-mm air space the heat-escape coefficient KCAL/M H is K = 3,00. The equivalent coefficient for synthetic framing is   K = 1,9.
 Taking heating prices (K) into consideration, we observe that with a synthetic window of dimensions 4’’x 15’’x 4’’ with double-glazing we can achieve about 60% savings over an aluminium window. The rubber of the synthetic framing must necessarily comply with the specifications of the German Manufacturing Standardization Number (DIN7863, type B) in order to withstand weather conditions and ultraviolet sunrays and to provide absolute sealing from rain and wind. With a properly installed plastic window, the air penetration into the interior space is 30 times less than that of a window made of conventional material. In particular, the measurements have shown absolute sealing of frames with hard PVC in winds of 55 - 120 Km/h.

 Combining the thermal and sound isolation properties specific to U-PVC material with double glazing and the most up-to-date mechanisms, we guarantee: superior thermal isolation that can maintain ambient temperature (K=1.9 KCAL/MH), sound isolation to the degree of 35-40 db, complete sealing from humidity and dust, even in conditions when high wind pressure is exerted on the frame (sealing effective against up to 600 Pascals, with resistance up to 1000 Pascals. Note: 600 Pascals is the equivalent of 11 Beaufort units of pressure), and dimensions that are not affected by the passage of time, (so that the efficiency of the frame isn't impaired).
