How to choose the right window: which double-glazed window to choose, the binding of the window, the supply valve for the PVC window.
The concept of a window is very familiar, but the troubles associated with it are very great. Firstly, due to ordinary windows, heat loss occurs up to 80% of the total loss of the building. Secondly, a lot of inconvenience is caused by drafts, street dust, noise, especially recently. Thirdly, among other things, the old generation wooden frames must be constantly prepared for the winter conditions: to glue all the cracks, constantly paint, change the seals, etc. Modern windows eliminate almost all of the above disadvantages.

Double-glazed window what to choose
The main changes affected translucent elements; double-glazed windows are used in modern windows. The unifying element of the glass is an aluminum frame (closed perforated profile).
The inner surface of the profile is filled with absorbent material. It regulates the air humidity in the double-glazed window, a thermal bridge can be built into the profile (it eliminates the contact of aluminum with the glasses). With the help of a sealant, glass and the distance frame are glued together, the inter-glass space is called a camera, there are several of them.
The heat-insulating and sound-insulating properties of the window depend on the number and width of the chambers, as well as on the thickness of the glasses. Due to the fact that an increase in the number of cameras leads to a weighting of the supporting elements of the window system (which requires a more reliable fastening of the window in the opening), therefore, the glazing elements are selected taking into account the regulatory framework and calculations.
The heat-insulating properties of a double-glazed window are increased due to the use of glasses with selective coating, as well as due to the filling of chambers with inert gases.
Noise-absorbing ability of double-glazed windows increases due to the fact that the density of gases filling the chambers is greater than that of air.
At the discretion of the customer, in the production of modern window systems, impact-resistant glass can be used. In the manufacture of skylights, in order to ease the load on the supporting structure, shock-resistant glasses with selective coating are installed in the skylights, the chambers are filled with inert gas.
Window Bindings
For the manufacture of bindings, PVC, aluminum, fiberglass profiles, or glued beams are used. More common are PVC or wood frames.
PVC binders have high technical characteristics, more affordable.
Wooden bindings are much more expensive, but attracted by their decorativeness and environmental friendliness.
PVC profiles have high thermal properties due to the use of several chambers in the window construction. The width of the window box varies from 48 to 150 mm., The stiffness of the window box creates a steel element placed in the largest chamber.
Wooden blocks are made of glued profiles made from timber. The beam is obtained due to glued between each other boards with a thickness of 20-30 mm. Lumber used in the production of timber is subjected to multi-stage drying, all defects are cut out, the strips spliced \u200b\u200balong the length into lamellas, the latter are glued under pressure.
The result of these manipulations is a strong, resistant to deformation beam with high thermal insulation characteristics. To preserve the texture of the tree, the outer layers of the timber are made of solid lamellas, in addition, the tree is impregnated with antiseptic compounds and covered with special varnishes.
It should be noted attic window systems that are installed in the plane of the roof. In the manufacture of such windows, high-quality coniferous wood treated with antiseptics is used. The special design of such windows, reliably protects against leaks, resists the most severe climatic conditions.
Wooden and PVC windows are equipped with the same fittings, the only exception is the fasteners of the hinges.
The color palette of PVC profiles is multifaceted, wood profiles are produced.
Window sashes can not only rotate around the vertical or horizontal axis, rise upwards, and also shift to the side, as shown in the figure: 1- flap, 2- flap, 3- swing-flap, 4- overhead flap, 5- sliding sash, 6- folding sash, 7- swinging sash, 8- swinging sash.
In addition to the fact that window systems eliminate drafts and noise, retain heat, but also look beautiful aesthetically, they are equipped with window sills, beautiful slopes and low tide for water flow.
Supply valve for PVC windows
Having done away with drafts, manufacturers, and most of all consumers of window systems, were faced with the problem of disruption of the natural ventilation of the room. According to the regulations, the air exchange in the room should be 3 cubic meters per hour, in the old windows, fresh air entered through the cracks.
The intake of fresh air during the operation of modern window systems can be ensured by opening the window leaf or a loose shutter, but the sound insulation is reduced.
The way out is the installation of supply air valves that allow forced and metered air flow. Among the simple and reliable self-ventilation developments, KBE systems are noted, one of them (Regel Air) can be mounted in already installed windows, providing a constant flow of air with the window fully closed, and noise and drafts do not pass into the room.
Mounting
If the junction between the window and the wall is incorrect, then all the advantages of the modern window system may be lost, so trust the installation of windows to specialists.
TRUST BUT CHECK. And in order for you to be able to check, you need the basic knowledge reflected in this article. Outside the joints are usually protected with a self-adhesive waterproofing vapor-permeable tape, from the inside of the room, the joints are sealed with special materials.
