Why Double Glazing Matters More On Large Door Openings
Double glazed doors are designed to reduce heat transfer through large areas of glass while helping improve indoor comfort and acoustic performance.
Because glazed doors often contain significantly more glass than an individual window, the glazing specification can have a major influence on how the surrounding living space performs.
For homes with large sliding, bifold or other glazed door openings, double glazing can help create a more comfortable transition between indoor and outdoor living without giving up natural light or views.
How Double Glazing Works
How Is A Double Glazed Door Built?
A double glazed aluminium door uses an insulated glass unit, commonly referred to as an IGU.
The unit contains:
Two Glass Panes
Two separate panes of glass form the internal and external surfaces of the glazing unit.
Sealed Insulating Cavity
A sealed space between the panes reduces direct heat transfer through the glass.
Spacer System
The glass panes are separated around the perimeter by a spacer that maintains the cavity between them.
Air Or Gas Fill
Depending on the glazing specification, the cavity may contain air or an insulating gas such as argon.
Custom Glass Selection
The individual panes can be specified with Low-E, laminated, toughened, tinted or other glass types depending on the performance required.

CHOOSE THE RIGHT CONFIGURATION
Which Door Type Is Right For Your Home?
Double glazing can be incorporated into a range of aluminium door systems. The best choice depends on the size of your opening, how wide you want it to open and how you use the surrounding space.
Sliding Doors
A practical option for large glazed openings where smooth operation and space efficiency are priorities.
Double glazing can improve thermal and acoustic performance while retaining the large glass areas that make sliding doors popular.
EXPLORE DOUBLE GLAZED SLIDING DOORS
Bifold Doors
Ideal for creating wide indoor-outdoor openings where multiple panels fold and stack to the side.
The glazing specification becomes particularly important across larger bifold configurations because of the total amount of glass involved.
EXPLORE DOUBLE GLAZED BIFOLD DOORS
French Doors
A classic hinged configuration combining traditional door styling with modern aluminium frames and insulated glazing.
Double glazing can improve comfort while maintaining the appearance and functionality of French doors.

Stacker Doors
Multiple sliding panels stack behind one another to create wider openings than a standard sliding door.
Double glazing can be specified where compatible with the selected stacker system.

Performance Section
Understanding Double Glazed Door Performance
Not all double glazed doors perform the same way.
Performance depends on the aluminium frame, glass type, cavity width, coatings and overall door configuration.
U-Value
U-value measures how readily heat passes through the complete door system.
Lower U-value = better insulation.
Our available systems:
SHGC
Solar Heat Gain Coefficient measures how much solar heat passes through the glazing.
The appropriate SHGC depends on the orientation of the opening, amount of direct sunlight and overall energy requirements of the home.
WERS Ratings
Compatible door and glazing systems can be assessed for energy performance under recognised Australian rating frameworks.
NCC 2022
The appropriate window and door specification can also form part of meeting the energy-efficiency requirements applicable to a new home or renovation.
Your required performance will depend on the project rather than double glazing alone.
Noise Reduction Section
Can Double Glazed Doors Reduce Outside Noise?
Double glazed doors can help reduce external noise transmission through large glazed openings.
The level of improvement depends on more than simply adding a second pane. Glass thickness, laminated layers, cavity width and the quality of the complete door system all affect acoustic performance.
If noise reduction is a major priority — particularly near busy roads, aircraft routes or commercial areas — the glazing should be selected specifically for acoustic performance.
Glass Options Section
Glass Options For Double Glazed Doors
The two panes within a double glazed unit can be configured to suit different performance requirements.
Low-E Glass
A specialised coating designed to improve thermal performance while maintaining natural light.
Laminated Glass
Two or more layers bonded together for additional safety and potential acoustic benefits.
Toughened Glass
Heat-treated safety glass designed to provide increased strength for appropriate door applications.
Tinted Glass
Helps reduce glare and solar heat gain while creating a darker contemporary appearance.
Obscure Glass
Provides additional privacy where clear visibility through the door isn’t required.
Acoustic Glass
Specialised glazing configurations designed to improve noise reduction where acoustic performance is a priority.
Thermally Broken Frames
Should Double Glazed Doors Use Thermally Broken Aluminium Frames?
Double glazing improves the performance of the glass, but heat can also travel through the aluminium frame surrounding it.
A thermally broken aluminium frame uses an insulating barrier between the internal and external sections of the frame to further reduce heat transfer.
For projects where thermal performance is a major priority, combining double glazing with a thermally broken aluminium system can provide a more complete solution.
Bigger Openings Without Compromising Comfort
Combine expansive glass, modern aluminium frames and insulated glazing to create brighter living spaces with improved thermal and acoustic performance.

Cost Section
How Much Do Double Glazed Doors Cost In Sydney?
Double glazed doors typically cost more than equivalent single-glazed systems because of the insulated glass unit, heavier glazing requirements and the door system needed to support it.
The final cost depends on:
- Door configuration
- Opening dimensions
- Number and size of panels
- Aluminium system
- Glass specification
- Low-E or acoustic upgrades
- Frame finish
- Hardware
- Installation requirements
For accurate pricing, we recommend measuring the opening and quoting the complete door system rather than comparing glass prices alone.

Condensation Section
What About Condensation On Double Glazed Doors?
Double glazing can help reduce condensation on the internal glass surface because the inside pane generally remains warmer than it would with single glazing.
However, condensation can still occur where indoor humidity is high or environmental conditions allow moisture to reach the dew point.
Condensation Between The Glass Panes
Moisture appearing inside the sealed cavity is different.
Condensation between the panes of a double glazed unit can indicate that the seal around the insulated glass unit has failed.
Where this occurs, the glazing unit should be assessed for repair or replacement.

FAQs
Frequently Asked Questions
What is a double glazed door?
A double glazed door uses two panes of glass separated by a sealed insulating cavity. The glazing is installed within a compatible door system designed to support the insulated glass unit.
What are the benefits of double glazed doors?
Double glazed doors can reduce heat transfer, improve indoor comfort and help reduce external noise while still providing large areas of natural light and outdoor views.
Are double glazed doors worth it in Sydney?
They can be particularly valuable where large glazed openings contribute to unwanted heat transfer, external noise or comfort issues. The benefit depends on the orientation, glazing specification, frame system and overall design of the property.
What types of doors can be double glazed?
Double glazing can be used with compatible sliding, bifold, French and stacker door systems.
[CONFIRM exact systems offered.]
Do double glazed doors reduce heat?
Yes. The insulating cavity between the two panes helps reduce heat transfer compared with equivalent single glazing.
Do double glazed doors keep heat out in summer?
Double glazing can help reduce heat transfer, but summer performance also depends on SHGC, glass coatings, shading and the orientation of the opening.
Do double glazed doors reduce noise?
Yes. Double glazing can reduce external noise transmission, although acoustic performance depends on glass thickness, laminate, cavity width and the complete door system.
What is Low-E double glazing?
Low-E double glazing includes a low-emissivity coating on one of the glass surfaces to improve thermal performance.
What is the difference between double glazing and laminated glass?
Double glazing uses two separate panes with a sealed cavity between them. Laminated glass bonds glass layers together with an interlayer. The two technologies can also be combined within the same glazing specification.
Can double glazed doors use tinted glass?
Yes. Tinted glass can be incorporated into compatible double glazed units where glare or solar heat reduction is required.
Can safety glass be double glazed?
Yes. Toughened or laminated safety glass can form part of a double glazed unit where required by the application and relevant standards.
What does U-value mean?
U-value measures the rate of heat transfer through the complete system. Lower values generally indicate better insulating performance.
What does SHGC mean?
SHGC measures how much solar heat passes through the glazing. The appropriate value depends on the orientation and energy requirements of the property.
Are thermally broken frames necessary?
Not always. However, thermally broken aluminium can further reduce heat transfer through the frame and may be beneficial where higher thermal performance is required.
How much more does double glazing cost?
The premium depends on the door type, dimensions, glass specification and aluminium system.
Can I replace single glazed doors with double glazed doors?
In many cases, yes. The existing opening can be assessed and a compatible double glazed aluminium door system manufactured to suit the project.
Can existing aluminium doors simply be fitted with double glazing?
Not necessarily. Double glazed units are thicker and heavier than standard single glazing, so the existing frame and hardware must be capable of accommodating them. In many cases, a new door system is required.
Do double glazed doors reduce condensation?
They can reduce condensation on the room-side glass surface by keeping the internal pane warmer. Condensation between the panes, however, may indicate failure of the sealed glazing unit.
Do you supply double glazed windows as well?
Yes. Double glazed windows can be coordinated with your doors to create a consistent aluminium and glazing package.
