Soundproof Double Glazed Windows in Singapore

Pang Giap is the supplier and contractor of double glazed soundproof windows in Singapore. Our windows are built to block out most unwanted sound from both outside and inside environments, making them highly effective for sound insulation. We have installed our soundproof windows for many residential properties such as HDB flats, condominiums and landed houses, as well as commercial buildings, home theatres, recording studios, karaoke rooms and hotels.

Double Glazed Glass with 1 Side Laminated

Our double glazed glass is around 18- 20mm thick. It is a 2 layer glass, consisting of 1 side laminated glass and other side floated glass, separated by a layer of air space.

Sound travels by vibrations. The laminated glass and floated glass have different thickness, weight and composition, they vibrate at different frequencies, therefore they make it harder for sound vibration to pass through. The laminated glass also help to absorb sound, which improve the sound insulation even further.

The air gap between the 2 layer of glass is fully sealed and filled with heavy inert gas. This serves as a special sound reducing chamber, therefore helping to weaken the sound wave before they pass through to the other side of the glass.


Heavy Duty Aluminium Frame

The window frame also needs to be sound insulated. Having soundproof glass without a sound resistant frame is insufficient. Our heavy duty frame is about 3 inch thick, as compared to normal window frame which is only around 1.5 inch. The thicker frame provides strong support for the double glazed glass, and it also serves as additional barrier to reduce sound transfer.


Soundproof Fibers inside Framework

Our high density fiber wool is an excellent sound absorber that is inserted inside our heavy duty window frame. The fiber wool absorbs sound energy, increase the density of the frame and reduce vibration caused by the noise, therefore greatly improves the overall sound insulation of our windows.

Multi-Point Locks System

Our multi-point lock system is a huge upgrade over traditional single point locks which only secure the window at the center. Our lock system consists of heavy duty window handle lock, with vertical shoot locks at the top and bottom of the window panel. When the window handle is turned (to close the window), the top and bottom shoot locks are activated at the same time, pulling the window panel tightly against the frame.

This allows the entire window to close more tightly and create more airtight seal at the top and bottom, not just the center of the window. As a result the soundproof performance of our windows is significantly improved.


Rubber Strip Seals for Soundproofing

We also have thick rubber strip seals installed on all 4 sides of our window panels. These rubber strips are sound resistant. When the windows are closed tightly, the seals compress firmly to close gaps around the edges and help prevent sound from passing through

FAQ on Soundproof Windows

1. Are double glazed windows soundproof? What is the difference between soundproof windows and double glazed windows?

Soundproof windows are a specialized type of window built for noise control. Double glazed windows are the most popular type of soundproof window because they use double glazed glass to reduce transfer of sound.

At Pang Giap, we use thicker double glazed glass with 1 side laminated glass, which make it harder for sound to pass through the window. On top of that, our company fill our heavy duty frame with high density fiber wool and use a multi-point lock system to block out the sound, therefore our double glazed windows are significantly better at soundproofing.


2. Are soundproof windows allowed in HDB flats?

Yes HDB homeowners are allowed to install soundproof windows as long as they follow the HDB guideline.

For HDB flats handed over from 1st July 2007 onwards, installation or replacement of new windows will need to follow the window configuration and colour originally provided by HDB.
But for the service yard, only the colour need to follow original window provided by HDB.

For older HDB flats (handed over before 1st July 2007) there is no restriction, homeowners can choose their preferred window types and colours.


3. Can soundproof windows block MRT or traffic noise?

Vehicles from traffic road, passing MRT trains, and general road noise give off constant and low-frequency sounds that can be disturbing and annoying. Our soundproof double glazed windows combined with airtight locking system can significantly reduce these noise to an extent that what used to be a loud distracting noise will now sound more like a soft hum – barely noticeable after some time.
