The importance of Broken bridge aluminum doors and Windows sound insulation cotton

Doors and Windows sound insulation important components: broken bridge aluminum doors and Windows sound insulation cotton

What is broken bridge window sound insulation cotton?

Broken bridge window sound insulation cotton is according to the broken bridge aluminum profile cavity shape made out of a specific shape of sound insulation cotton, is filled in the cavity of the profile inside the strip sound insulation cotton.

The function of sound-proof cotton on broken bridge

1,The primary role of sound insulation cotton is sound insulation. It can absorb the sound inside and outside. The broken bridge window filled with sound insulation cotton can be improved by 7~12% on the basis of original sound insulation effect of the broken bridge window. Let's take a look at how soundproof cotton works:

Indoor and outdoor objects vibrate to produce sound → sound wave in the air transmission → soundproof cotton has a multi-fiber structure → sound wave through soundproof cotton after numerous fiber reflection, overlapping, collision, acoustic energy into heat energy (the generated heat energy is very small, can be ignored) → sound intensity weakened → sound disappeared.

It is important to use soundproof cotton in roadside houses, so that you can sleep safely even on noisy roads. And even if is again big wind and rain also won't have the sound that rain hits window profile to give out.

2, broken bridge insulation cotton another important role is heat insulation. Use of sound insulation cotton good insulation effect, inside the doors and Windows profile cavity filling sound insulation cotton, which can effectively avoid indoor and outdoor temperature conduction and hedge, is simply the summer can effectively block the high temperature through the aluminum to the indoor outdoor and indoor air conditioning air to outdoor, winter, on the other hand, to be more energy conservation and emissions reduction, make you less pay the electricity bills at the same time can make furniture to avoid summer heat and prolong life.

3, reduce and effectively alleviate the broken bridge aluminum metal fatigue, prolong the service life of doors and Windows.

The cause of metal fatigue of aluminum profiles is the uneven structure inside the metal, resulting in the imbalance of stress transfer, and some places will become the stress concentration area. When the part of the material that can transfer stress is out of balance, the metal is prone to deformation and damage over time.

Broken bridge sound insulation cotton purchase

1. Material selection

Sound insulation cotton in the production and processing of the choice of raw materials variety, common mineral fiber, glass fiber, polyester fiber, high density sponge and so on. All kinds of sound insulation cotton have high and medium frequency sound absorption performance, but the low frequency sound absorption coefficient is relatively reduced. Bridge profiles are usually filled with environmentally friendly polyester fiber, safe and tasteless.

2. Discrimination of internal structure

Sound-proof cotton is fluffy material. It should be noted that the interior is fluffy and staggered, with a large number of holes connected inside and outside, and the material is evenly distributed. Feel soft elastic, smooth surface, it is a better sound insulation cotton.

3. Fire resistance test

Can use open flame ignition inspection, high quality sound insulation cotton has the role of fire prevention and flame retardant.
