German, Soundproof, Aluminium Windows
Your windows and doors are the weakest part of your property. In fact, over 85% of windows and doors installed in Malaysia today, offer little protection from noisy roads, construction or airplaines.
Noise stress is a major cause of illness. It not only damages one’s hearing, it also leaves persistent marks on the human psyche. If you want to learn more, check out the
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.
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 70 dB (road traffic)
2. Desired room noise 35 dB (bedroom)
= The difference is 35 dB
In this case, a 35 dB rating is required for your soundproof window and door system.
Complete silence, whatever happens outside
- Laminated, soundproof glass
- Multi-chamber profile system to maximize sound reduction
- German hardware to ensure smooth function and tight sealing
- Professional installation with high-grade Polyurethane Foam
Select the right aluminium profile
Every Malaysian Window Manufacture claim to be able to offer Soundproof Windows. By checking their profile sections, you can find out the truth. Most of the time they are using just a standard profile, put in a laminated glass, and rename the product. For soundproofing you need special designs. Otherwise, the windows will lose performance latest after the first year of use.
Select the right glass
Soundproofing requirements vary widely. Our professional staff will help you determine which glass is most suitable, based on your location and the desired soundproofing level.

Terms & Explanations:
Rw [dB] is the weighted sound reduction index
STC [Sound Transmission Class] The STC rating was created to provide a single number rating for interior building partitions that are subjected to interior noises such as speech, electronic devices, office equipment and other mid to high frequency noise sources. STC ratings are calculated in accordance with ASTM E413 over the frequency range of 125 to 4000 hertz.
OITC [Outdoor-Indoor Transmission Class] The OITC rating was created to provide a single number rating for facades and facade elements in relation to exterior noise from aircraft, trains, automobiles, and other low to mid frequency noise sources. OITC ratings are calculated in accordance with ASTM E1332 over the frequency range of 80 to 4000 hertz.
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.
