Living on the side of the road, the choice of soundproof door and window profiles


In addition to the glass that accounts for the largest area in the early products of soundproof windows, there is also a profile that cannot be ignored. There are four common profiles on the market, broken bridge aluminum, UPVC plastic-steel profiles, aluminum-clad wood, and aluminum alloys;

The thermal insulation and sound insulation effects of aluminum alloys are not very good, and it is not recommended.

Broken bridge aluminum profile

Concept: Broken bridge aluminum is also called thermal insulation broken bridge aluminum profile. "Bridge" refers to the "cold and hot bridge" in the sense of material science.

Product Features:
Because aluminum alloy is a metal and conducts heat quickly, when the indoor and outdoor temperatures are very different, the aluminum alloy can transfer heat as a "bridge", and the thermal insulation performance of doors and windows will be poor. The broken bridge aluminum is to disconnect the aluminum alloy from the middle, and use hard plastic to connect the disconnected aluminum alloy.

Broken bridge aluminum profiles are mainly made of metal. In terms of physical properties, the metal itself has a low sound insulation coefficient, so the sound insulation of broken bridge aluminum is weak; The temperature is less than -10°C in winter in the southern area, but in the cold northern area, the broken bridge aluminum will freeze and frost at -10°C, and the thermal insulation performance will decrease.

UPVC profile

Concept: UPVC profile refers to a new type of plastic-steel profile that is improved on pvc plastic-steel. Usually, steel is added to the profile cavity to enhance the firmness of doors and windows.

Product Features:
The thermal conductivity of the non-metallic material itself is poor, which makes the thermal conductivity of the plastic-steel profile low, and it is easy to achieve a low heat transfer coefficient when making doors and windows, which is an ideal material. Due to its excellent physical properties such as rigidity, elasticity, corrosion resistance and aging resistance, it is usually a good substitute for non-ferrous metals such as copper, zinc and aluminum.

UPVC profiles are welded by high temperature heat fusion, without any gaps and high sealing. They belong to multi-cavity profiles. The sound transmission from the cavity structure will be attenuated layer by layer. In the north, the weather is cold and in order to save energy, the proportion of plastic steel windows is very high. Large, the market share of plastic steel windows is very high.

For a window, the profile accounts for 15% of the entire area, and the sound insulation coefficient of the profile will affect the sound insulation effect of the entire window.If you want to have a window with a high sound insulation coefficient, Baydee is a good choice.We are BAYDEE UPVC profile manufacturer from China - our products are sold all over the world, there are UPVC profiles, UPVC aluminum profiles, UPVC windows, UPVC doors, UPVC sliding windows, UPVC casement windows, UPVC swing doors, etc.
