Soundproof Window Singapore: How To Reduce Outdoor Noise

Living near a busy road, construction site or MRT line can make it difficult to sleep, work or simply relax at home. If closing your windows barely changes the noise, sound may be entering through thin glass, loose panels, worn seals or gaps around the frame.

A properly designed soundproof window in Singapore can reduce intrusive noise, although no window can guarantee complete silence. Effective soundproof windows require the glass, frame, seals, hardware and installation to work as one system.

Top 1 Singapore Safety Window assesses your existing windows and property requirements before recommending a suitable solution. Whether your home faces an expressway, playground, or MRT tracks, we help you choose a practical system.

How Loud Are Traffic and MRT Noise in Singapore?

An NUS study found Singapore’s daily average outdoor noise level was 69.4 decibels. It also found 27% of monitored outdoor sites had noise levels of 70 decibels. For context, normal conversation is generally around 60–70 dBA.

This helps explain why road traffic outside your home can stay loud. This is especially true when heavy vehicles, motorcycles, or horns create louder peaks.

Above-ground MRT noise can be even more noticeable. A Singapore transport study citing LTA states that an MRT train on an above-ground track can generate approximately 80-85 decibels. However, the level reaching your window varies with distance, floor height, track condition, barriers and surrounding buildings.

Why Noise Still Enters When Your Windows Are Closed

Even a small opening around a panel or frame can admit noise. Common problems include ageing seals, misaligned panels, open frame joints and poorly sealed edges.

Different sounds require different solutions. Voices, horns and tyre noise differ from low-frequency buses, trains and machinery. Impact noise may also travel through the building structure, so contractors should assess the site.

Sound can also pass through doors, ventilation openings, air-conditioning gaps and lightweight walls. Identifying the main source avoids upgrading the glass while leaving another major leak untreated.

How Do Soundproof Windows Reduce Noise?

An effective system combines layers, separation and airtightness. Its components must work together.

Double Glazed Windows and the Air Gap

Double glazed windows contain two panes separated by a sealed air gap, helping interrupt sound transmission. Performance depends on the glass thickness, pane combination, cavity depth and sealed-unit quality.

Airtight Aluminium Frames and Seals

Durable aluminium frames can support heavier glazing. But frame design, fabrication, gaskets, locks, and perimeter sealing determine how tightly the window closes. Casement windows generally seal more tightly because their locks compress the sash against gaskets. Secure and seal the frame joints carefully so sound cannot travel around the new system.

You need soundproof windows if you are staying near:

• MRT tracks or expressways.
• Road-facing living room and bedrooms.
• Construction or playground noise.
• Have a home office and study room.

Can you install soundproof windows in an HDB flat?

Yes, provided the work follows HDB’s current requirements and the proposed design suits the opening. HDB says owners must hire a BCA-approved window contractor from its directory to install or replace aluminium windows. Restrictions limit some full-height window replacements, so workers must inspect the existing opening before work begins.

Top 1 Singapore Safety Window is an HDB-licensed window contractor (licence HB-04-4658E). We can assess your HDB flat, explain the relevant requirements and recommend a compliant configuration. For condominiums, homeowners should also check applicable MCST façade and renovation rules.

Our Soundproof Window Installation Process

1. Assessment and Measurement

We inspect and measure the opening, seals, and likely sound paths. Then we identify if the main noise comes from traffic, trains, construction, or voices.

2. Recommendation and Quotation

We recommend the window style, glazing, frame, and hardware. We explain the trade-offs between ventilation, noise control, space, and budget. The quotation clearly states the proposed specifications and installation scope.

3. Fabrication and Installation

The window is fabricated to size. The frame is positioned, secured, and sealed around its perimeter. Panels, locks, and gaskets are adjusted for consistent closure.

4. Final Inspection

We check alignment, operation, hardware and finishing before handover, then explain basic care.

How Much Do Soundproof Windows Cost in Singapore?

Prices depend on the panels, opening size, window style, aluminium profile, glazing specification, hardware, and installation complexity.

Request quotations based on equivalent specifications. Top 1 provides a customised quotation after assessing the opening and understanding your noise-control priorities.

Frequently Asked Questions

Can soundproof windows block all outdoor noise?

No window can guarantee total silence in every property. A double glazed window system can reduce noise. Results depend on frequency, distance, building construction, and other leakage paths. People may still hear low-frequency vibration and sound travelling through walls.

Are double glazed windows always the best option?

Double glazing can be effective, but pane selection, air gap, seals and frame construction all matter. A site assessment helps identify the practical option.

Is casement better for noise reduction?

Casement windows generally seal more tightly because they close against compression gaskets.
