Noise affects our quality of life, and many Australian families are willing to invest in AS2047-certified acoustic windows for a quieter home. This guide walks you through how to choose the right aluminium acoustic windows — step by step.

‍

1. Identify Noise Source & Floor Level

Different noise types (low, mid, high frequencies) require different treatments. Upper floors face more wind or distant sound, while lower levels suffer more from street and vehicle noise.

Tip:If you live near a road or railway, go for double glazed or laminated glass for stronger low-frequency noise reduction.

‍

2. Glass Layers & Types

The glass plays a major role in noise reduction, but it’s not just about thickness.

Double Glazed Glass
Structure: Two glass panes separated by a sealed air space or filled with inert gas (such as argon).
Features:

Thermal insulation: Greatly improves energy efficiency, keeping interiors warm in winter and cool in summer.

Good sound reduction: Provides decent noise control, though not as consistent as laminated glass.

Energy-saving & eco-friendly: Reduces reliance on air conditioning and heating systems significantly.

Laminated Glass

Structure: Two glass panes bonded together with a PVB (polyvinyl butyral) interlayer.
Features:

High safety: When broken, the glass remains in place without shattering or flying apart — ideal for balconies and floor-to-ceiling windows.

UV protection: Blocks most ultraviolet rays to protect furniture and interiors from fading.

Excellent sound insulation: The interlayer effectively absorbs and reduces noise.

3. Frame Materials Matter

Many overlook the frame — but it’s just as vital.

Thermal-Break Aluminium is a high-performance aluminum window with a thermal insulation structure.Its core technology lies in the use of a polyamide strip inserted between two layers of aluminum profiles, which effectively blocks heat transfer and improves overall energy efficiency.Thermal-break aluminium reduces heat transfer and improves sealing. Compared with basic aluminium or uPVC, it’s more stable under Australian weather conditions.

‍

4. Sealing & Installation Quality

Even the best window won’t perform if it’s poorly installed.

✅ Proper installation should include:

Three sealing layers (outer/middle/inner)

Sealant or foam between frame & wall

Smooth operation and solid hardware

Poor installation causes leaks, vibration noise, and seal deformation.

‍

5.Post-Installation Checklist

After installation, do the following checks:
Glass intact — no scratches or detachment
Frame sealed with no visible gaps
Remove protective film after installation
Small details determine long-term performance.

‍

‍

6. Expected Sound Reduction Level

A comfortable indoor sound level is around 35 dB.
A typical double-glazed aluminium system can achieve around 20–25 dB noise reduction when properly installed.

‍

‍

7. Balancing Budget & Performance

If you’re on a budget:
Opt for thermal-break aluminium + double glazing + quality sealing.
If you need maximum quiet:
Upgrade to triple glazing or laminated combinations.
