How to increase acoustic insulation parameters
Factors
What influences a window's soundproofing?
- number of seals,
- window profile (frame and sash elements),
- glazing type and thickness,
- number of panes,
- type of gas filling the space between the panes (using e.g. argon),
- tightness of the connection between the frame and the sash,
- installation (proper installation ensures proper sealing).
Effective soundproof windows are the result of a complex combination of various factors. It is worth educating customers about these aspects to help them make an informed choice.
Material
First, let's take a look at the materials that will effectively mute the noise coming from outside. uPVC windows is definitely worth mentioning here - it offers better parameters than aluminium due to its greater porosity.
Wood is an effective acoustic insulator. Why? Due to its porous structure, it naturally absorbs sound. It is worth looking at specific types of wood and paying special attention to their density. Moreover, thicker wooden elements will offer better acoustics than thinner ones.
Glazing units
The most important thing in the context of insulation is the choice of glazing. Of course, the thicker the unit, the better the insulation. A suitable option will be a unit with three panes rather than two or one - not only the glass itself plays a role, but also the space between each layer.
Pay attention to the type - perhaps the right solution for your client will be the use of sound-absorbing glass. It is a laminated glass with a special acoustic foil.
Sound-absorbing glass is carefully tested to express the Rw coefficient - a weighted attenuation value - the higher the value, the better the acoustics. Rw is calculated based on the results of laboratory tests that simulate conditions associated with road traffic noise.
What else is worth remembering? The finishing of the whole element is also important - proper installation can further reduce the transmission of sounds. Only if carried out correctly will it provide us with the expected acoustic insulation.
It is worth mentioning these different aspects to the client to help him decide on a solution tailored to his specific needs. Properly selected and installed soundproof windows can significantly improve the comfort of life, especially in places exposed to intense noise.
