The Glass


To illustrate the allegations set forth above, it is worth examining the scheme of sound transmission through the window. From the viewpoint of acoustics, the window installed in the window opening is a heterogeneous structure consisting of several elements, differently affecting the transmission of sound in the room: the elements of the profile system – part of the frame and cover; glass and assembly seam. Accordingly, soundproof window assembly largely depends on its size, the nature of fragmentation bindings, as well as the area ratio of transparent and opaque parts. Provided good seal windows bulk of the penetrating sound falls on the glass. (A valuable related resource: The Wellington Block). Sound transmission through windows is as follows: Sound waves strike the exterior glass, which has a mass of 1 m2 m1 and cause a It swings. Located in the interlayer air acts as a shock absorber, which these oscillations are damped. Thus, on the inside glass with a mass of 1 m2 m2 comes already weakened sound effects, which, in turn, excite vibrations in the glass.

Fluctuating internal glass radiates sound into the room. One of the common causes of window replacement is the desire to protect your home from external noise (roads, trams, bustling streets, etc.). Company based on technical specifications and years of experience, can offer you a complete solution, using the profile system VEKA TOPLINE. Profile system 70-millimeter profile VEKA TOPLINE allows the use of double-glazed windows of various designs, which creates the possibility of designing window assembly with the specified noise protection properties. Improved sound insulation glass is achieved through the implementation of a complex special events: the optimal selection of the ratio of thickness of glass and air gap, filling the internal chamber glass gases, the velocity of sound waves that is different from the air, and also through the use of multi-glazed window glass (triplex) with a special intermediate layer – acoustic film.

The table shows the acoustic characteristics of the one-leaf swing-out windows PVC, made from system profiles VEKA TOPLINE, which set windows of various designs. For a more graphic representation of data in the table in Figure 3 shows a comparison of the frequency characteristics of insulation traffic noise window units with different glazing. As a result, the construction of comparative graphs, we can evaluate the effectiveness of the use of a constructive measures aimed at improving sound insulation of wooden windows. So: All elements of sound insulating window assembly must demonstrate the high stability of the working properties over a long operational period. For perform its functions effectively noise protection window should be as tight and keep this property during the entire billing period of operation.
