Innovation in Vitron

Vitron was the first manufacturer of PVC joinery in Poland, and probably also in the world, to develop an innovative technology for conditioning PVC window sashes as part of the window production process. This technology has been patented (Patent No. 233594 for the invention of PT. Method of manufacturing PVC windows and production line for manufacturing PVC windows). The conditioning process allows to obtain PVC windows with increased parameters of resistance to permanent deformation due to the heat of the sun. Warping of window sashes, especially balcony doors, is a frequent phenomenon, very burdensome for the user, as well as for the manufacturer, who in order to eliminate this phenomenon must perform the procedure of “heating” the sashes at the place of installation. The effectiveness of the PVC window sash heating technology has been confirmed by a number of tests carried out for our company by the Institute of Innovation and Technology of the Białystok University of Technology (ITT) under the supervision of Dr Marek Jałbrzykowski. On order and according to the guidelines of Vitron sp. j. ITT has made a project and a stand for conditioning of PVC.  It allows us to heat treat PVC window sashes welded and armed with steel, while maintaining the established parameters (time and temperature). This process eliminates the so-called secondary contraction already at the production stage, which excludes permanent deformation of PVC window sashes caused by heating by sunlight.

Aesthetics is an issue that cannot be overlooked, because a good product is not only the one with the right parameters, high quality workmanship, but also the one that “pleases our eye”. In order to improve the aesthetics of the windows we produce, we have modernized our production line so as to have the possibility of using a non-blocking weld, which definitely increases the visual value of the window. The additional benefit resulting from the introduction of this technology is increasing the strength of the weld by 20%, and thus making our windows more durable.

Another important aspect of our organization is the development of technology to ensure the best possible thermal insulation of windows. As a result of our own research work, we have developed a system of using an expansion band between the pane and PVC profile, which reduces heat transfer. In order to verify our research, we handed over a prototype of PVC joinery to ITT in order to conduct professional and scientific research of our product. The tests carried out by ITT confirmed the increase of thermal insulation of the wing by 10%, and additionally, the confirmed benefit of using an expanding band is the increase of soundproofing by 6%. The improvement of the thermal insulation parameters of the windows translates into a significant reduction of heating and air conditioning costs.
