A reliable design of metal -plastic windows provides them with simply unique consumer properties. To choose an analogue of these constructions that would cost at least the same amount and, at the same time, would be reliable, durable and aesthetically beautiful, impossible. These products are ideal for glazing a residential apartment. It is just right to ask the question of what lies the secret of success? To answer this question, you need to understand how thoughtful the structure of the window block is.
Structural elements
The window block consists of the following elements:
Profile – is responsible for the sound – and thermal insulation properties of the structure and determines the appearance of the block;
double -glazed window – a new word in the area of installation of glasses in window structures. It is a hermetic package that can consist of one, two or three glasses. Accordingly, the number of air chambers (gaps) also depends on their number. The consolidation of this element in the block frame is carried out using special profiles (graduates). The use of a three -chamber double -glazed window allows you to maximize the sound – and thermal insulation properties of window structures. A distinctive feature of the double -glazed window – convenience during operation and functionality;
slopes – used to finish the opening from above and on both sides of the block. During the replacement of old structures, critical damage is caused by new slopes. Therefore, their restoration is required. Typically, slopes are arranged using noise -disposable plastic panels, which also have good heat -insulating properties. As a result, the window block has a finished look. The sloping procedure is extremely simple and completely unrelenting;
window sills – during the installation of the described type of designs, old window sills are subject to dismantling. Their use with modern window blocks is impossible. Plastic window sills are installed by fixing them on the front profile. They not only have a pleasant appearance, but also have excellent strength characteristics. A wide range of decorative coatings allows you to give the windowsill (and, accordingly, to open) the necessary entourage;
Following profile – is an auxiliary element that is used for the “rigging” of the described products. Before the start of its mass use when moving along the rough surface, the window structures often scratched. Now, the scratches, if they remain, then only on the front profile. In addition to the supporting function, it plays the role of the base to which the external and internal window sills are attached;
ebb – the outer element of the block, which is responsible for the removal of rainwater. In addition, it is an excellent protection of the mounting seam.
High -quality fittings for metal -plastic windows – a constructive element that deserves a separate consideration. These are all kinds of loops, pens, constipation, latches, brackets and jackets. These elements can be made of plastic, steel, aluminum alloys. If they were selected correctly, then not only the indicators of tightness and sound insulation increase. High -quality constructive element also affects the durability of the block. In addition, here we can talk about improving the aesthetic characteristics. By the way, the desire to save by acquiring cheap handles, a loop and other mechanisms nullifies the quality of the best window profile in the world.
