Most heat escapes through a double-glazed window, so you should pay close attention to it. Often, to improve the characteristics, silver ions are sprayed onto the surface or argon gas, which has low thermal conductivity, is pumped inside. As a result, such double-glazed windows are more expensive, but they also retain heat 1.5 times better than ordinary ones.
What you need to know when choosing pvc windows When you want to buy plastic windows, you get the feeling that they are all the same. White in color, with similar handles, glasses and seals - you just need to say the dimensions and choose those that are cheaper. But in this case there are many nuances that it is desirable to know when choosing a window.
Profile drainage holes Thermal insulation properties of the window depend on the number of chambers. There must be at least three of them for cold glazing of balconies, loggias and technical rooms and at least 5 for windows of residential premises, offices, retail establishments, hospitals and schools. PVC profile with 3 chambers PVC profile with 3 chambers. PVC profile with 5 chambers PVC profile with 5 chambers.
Rubber In terms of performance, rubber seals are not inferior to silicone and ethylpropylene, but at a much more affordable price. True, soft rubber is not very durable and eventually cracks from frost and heat, losing tightness. But it is just as easy to replace as the TPE seals, so there will be no problems with it.
Choosing plastic windows: video instruction from an expert The video contains recommendations for working with a calculator on the exprof website, which will help you select all the important characteristics of a window structure in our configurator and send an application for production.
Most of them are made on the basis of high-quality float g
Polyvinyl chloride itself for windows was not chosen by chance. This synthetic material is distinguished by: high weather resistance; low coefficient of thermal conductivity; low cost of production; environmental friendliness; excellent adhesion to most types of paints and varnishes; durability (at least 50 years of preservation of the main properties); weak conductivity of sound vibrations.
Reinforced profile PVC profile and negative temperatures One of the important characteristics of metal-plastic windows is frost resistance. This is the ability to maintain the integrity of all elements and heat-saving properties at a certain temperature. For the Russian climate, it is necessary to choose windows marked with the “M” index - frost-resistant. They retain all their characteristics down to -20 0C.
What technical characteristics of the PVC profile should be taken into account The term "profile" in relation to plastic windows and doors means the material from which the frames and sashes are made. For vertical and horizontal elements in PVC windows, a complex structure made of metal (aluminum or steel) and polyvinyl chloride is used. In cross section, it presents several longitudinal cavities separated by sealed walls. Such cavities are called chambers, the more of them, the theoretically better - the windows become warmer and stronger.
What does a plastic window consist of? Profile is the main element of a window block. Its purpose is to combine other components into a whole structure.
