Product Description

Double glazing refers to the installation of two panes of glass with a spacer in between, creating an air gap that improves insulation. This type of glazing provides excellent thermal and acoustic insulation by reducing the transfer of heat and noise between the inside and outside of your home.

Our double glazing windows come in a variety of styles and configurations, offering the perfect solution for any room in your home. From maintaining temperature control to enhancing privacy, double glazing windows from ATCO Windows are a smart investment that helps reduce energy costs and improve your home’s comfort.

Noise Reduction: Double glazing is known for its soundproofing qualities, helping reduce external noise such as traffic, barking dogs, and neighbourhood disturbances.
Energy Efficiency: The air gap between the two panes of glass acts as an insulating barrier, keeping your home cooler in summer and warmer in winter. This helps reduce the strain on your heating and cooling systems, lowering energy bills.
Improved Comfort: By maintaining a more consistent indoor temperature, double glazed windows enhance overall comfort throughout your home.
UV Protection: The dual-glazed windows help block harmful UV rays, preventing your furniture and upholstery from fading.
Enhanced Security: Double glazing increases the strength and durability of your windows, offering an added layer of security against break-ins.

WERS Explained

When comparing double-glazing windows, understanding WERS (Window Energy Rating Scheme) is essential. WERS windows are independently rated to indicate how well a window system performs in terms of energy efficiency.

WERS ratings consider:

Heat gain and heat loss through the window
Air infiltration
Overall system performance (frame + glass combined)

For homeowners and strata committees reviewing double-glazed windows in Sydney, WERS ratings provide a consistent way to compare products across suppliers. Our systems are aligned with performance expectations for modern aluminium windows.

U-Value And SHGC

Two key performance metrics often referenced in thermal assessments are U-value and SHGC.

U-value (Uw): Measures how much heat passes through the window system. Lower values indicate better insulation.
SHGC (Solar Heat Gain Coefficient): Measures how much solar heat enters through the glass. Lower values reduce heat gain in warmer climates.

Together, these metrics define how thermal break windows and glazing systems perform across seasons.

For Sydney conditions, balancing insulation and solar control is important for maintaining indoor comfort.

Acoustic Glazing Stack-Ups

For properties exposed to traffic, construction, or urban noise, acoustic double glazing can improve indoor conditions significantly.

Typical glazing configurations include:

Laminated glass combined with air gaps
Asymmetrical glass thickness (e.g. different pane thicknesses)
Double glazing paired with improved sealing systems

Performance depends on the full system, including frame quality and installation accuracy. Acoustic glazing is commonly used in apartments and strata buildings seeking improved noise control.

Strata Approval Checklist

Upgrading to double glazed windows in Sydney within a strata building requires planning and approval.

A typical checklist includes:

Confirmation of whether windows are common property
Committee approval for replacement scope
Consideration of façade consistency
Product specifications and performance details
Installation method and access planning

For building-wide upgrades, coordination is often managed through dedicated services such as strata windows and doors.

Comparison Table

This comparison helps homeowners and strata managers evaluate performance outcomes against budget and project scope.

FAQs

What Are WERS Windows?

WERS windows are rated systems that measure energy performance, including heat transfer and air leakage, helping compare different window products.

Are Double Glazed Windows Worth It in Sydney?

They can improve thermal comfort, reduce noise, and lower energy use, especially in high-density or exposed areas.

What Is the Difference Between U-Value and SHGC?

U-value measures heat transfer, while SHGC measures solar heat gain. Both are used to assess window performance.

Can Acoustic Double Glazing Reduce Traffic Noise?

Yes. Acoustic glazing configurations can reduce external noise significantly when properly installed.

Do Strata Buildings Need Approval for Window Upgrades?

In most cases, approval is required, particularly when changes affect the external appearance or common property.
