German, soundproof, aluminium windows

Do you have a noise problem?

Your windows and doors are the weakest part of your property. In fact, over 95% of windows and doors installed in Malaysia today, offer little protection from noisy roads, construction or airplaines. Even worse, they do not offer sufficient protection from burgularly and are often found to be leaking.

Aluminium windows reduce highway and traffic noise.

What can noise do?

Noise stress is a major cause of illness. It not only damages one’s hearing, it also leaves persistent marks on the human psyche. For many years, effective protection against undesired noise has not merely been a matter of comfort, but a decisive issue in health protection. If you want to learn more, check out the Q-Windows Noise Brochure.

Reduce perceived noise by up to 99%

A proper sound insulation can only be achieved when all components play well together. The final sound insulation factor depends on the weakest element. Therefore it’s important to take all factors such as glass, profile and installation into consideration.

If the sound level (volume) drops by 10 dB, it is perceived as half as loud.

Conversely, if the sound level increases by 10 dB, it is perceived as twice as loud.

Compare soundproofing level

Press the button to compare the different noise levels and sound reduction level one (-32dB) and two (-40dB).

Determine healthy sound level

Recommended sound level

Bedroom 30 - 35 dB
Study room 35 - 40 dB
Living room 40 - 45 dB
Home office 45 - 50 dB

By subtracting the recommended indoor noise level from the typical outdoor noise level, you can estimate the appropriate acoustic performance for your windows.

Example calculation

1. External noise source: 76 dB (road traffic)
2. Desired room noise level: 35 dB (bedroom)
= The difference is 41 dB

In this case, a 41 dB rating is required for your Q-Windows window and door system.

The above data is based on testing done by laboratories and internally as well as data published by glazing suppliers. It serves as a guide only. The sound reduction is only as strong as the weakest building element. It is necessary to check the sound reduction values of windows, wall and roofing as a whole. For projects that require fully tested & certified performance data, please get in touch with our specialist. We will work out a solution that suits your needs with soundproofing solutions with up to 64 dB total sound reduction.
