The properties of the double-glazed window determine the heat and sound insulation of the window block, as well as the degree of natural light in the room. Fittings play an important role in the usability and durability of the translucent structure. Details such as constipation, clamp, scissors, handle, bar are responsible for the possibility of opening the sashes in different ways.
Our calculator will help you not to overpay for unnecessary design improvements. Select the main parameters: city of residence, type of premises, floor, heating system power, noise level. Then you will be able to determine the most significant design parameters, choose the width and chamber profile, standard or energy-saving double-glazed windows, configuration (window block type, number of sashes, opening method), select accessories and evaluate the cost of additional services.
More than 5 cameras can be found in quality products of well-known brands, but already 7 cameras are a clear overkill. Studies have shown that with a noticeable increase in weight, thermal conductivity begins to increase - it is not the volume of the air gap that comes first, but the thermal properties of the wall partitions, which conduct heat better than air.
To reinforce the plastic profile, special steel inserts are used, which are mounted directly into the main chamber of the PVC profile. The thickness of steel reinforcement in translucent PVC structures according to GOST should not be less than 1.5 mm.
PVC used for the production of profiles has a number of features that manufacturers are constantly struggling with: 1. Sufficiently high linear expansion, reaching several millimeters per meter of length. In order to compensate for this phenomenon, it is necessary to leave special gaps, use reinforcement and correctly calculate the number of fasteners. The same feature of the PVC profile limits mamaximum dimensions of window structures. 2. Low coefficient of elasticity, but even at the factories it is leveled by the use of metal inserts and the correct calculation of the thickness of the inner walls, which are stiffeners. 3. Insufficient temperature stability and UV resistance. Manufacturers also learned to deal with this drawback by introducing special modifiers and stabilizers into PVC, which preserve the color and structure of the material. In high-quality windows, such additives serve no less than the entire structure. They are, in most cases, completely harmless to humans. But if the frame emits a pungent smell that does not disappear for a long time, do not buy this window. It used lead or cadmium, or even more dangerous chemicals, instead of harmless zinc and calcium.
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.
Fittings Before choosing a plastic window, pay attention to fittings. It must: meet high strength and durability indicators: the best operational properties are shown by fittings with an external anti-corrosion coating; be multifunctional: easy to open, close, provide multi-stage, automatic, emergency, ventilation, scheduled operation, guarantee protection against unauthorized entry (break-in), prevent attempts to control children.
The window selection procedure is based on a number of criteria that guarantee the user: reliable protection from external noise (which is important for apartments in a metropolis) energy efficiency; protection from rain, wind and cold; protection against unauthorized intrusions; ease of use; durability (at least 10 years).
Reinforcing insert Reinforced windows are stronger and more durable. Reinforcement is an essential component of a high-quality translucent structure. It is necessary so that the windows can resist wind loads, and also do not deform due to thermal expansion. This is especially true for regions with significant temperature fluctuations throughout the year.
The choice of windows for an apartment Before choosing metal-plastic windows for an apartment, you should decide on the manufacturer. Giving preference to such a brand as REHAU, the consumer has a chance to purchase a reliable window with energy-saving double-glazed windows in Kyiv. Video: How to choose windows in an apartment?
