Double and Triple Glazing Questions
What is double glazing?
Double glazing consists of two panes of glass with a sealed cavity between them, typically filled with argon gas for enhanced insulation. This design significantly reduces heat transfer and sound transmission compared to single-pane windows, improving both energy efficiency and acoustic comfort in your home. Explore the benefits of double glazing.
What is the difference between double and triple glazing?
Triple glazing has three panes of glass with two insulating cavities, offering superior thermal and acoustic performance compared to double glazing. While double glazing is suitable for most Australian climates, triple glazing is ideal for extreme temperature zones, high-noise areas, or when maximum energy efficiency is desired.
How much can I save on energy bills with double glazed windows?
You can save up to 80% on your heating and cooling bills by replacing single glazed windows with our double glazed systems. The exact savings depend on your home’s size, current insulation, and climate, but most customers notice a significant reduction in energy costs within the first year. Read more about energy saving benefits.
Do double glazed windows work in the Australian climate?
Yes, double glazed windows are highly effective in the Australian climate. They improve thermal resistance by up to 94% depending on glass selection, blocking heat from entering in summer and preventing warmth from escaping in winter. All our products are specifically rated for Australian conditions. Check out our glass types for more information.
Noise Reduction
How much noise reduction can I expect from double glazed windows?
Our argon gas-filled double glazed windows can reduce noise by 34-45 decibels (dB) depending on the glass selection and cavity width. For maximum noise reduction, we offer specialised acoustic glass options with wider cavities between panes. Learn more about overcoming noise issues.
Are double glazed windows effective for reducing traffic noise?
Yes, double glazed windows are highly effective at reducing traffic noise. Windows are typically the weakest point for sound insulation in homes, and upgrading to our double glazed systems with proper sealing creates a significant barrier against external noise pollution, providing a quieter, more comfortable living environment.
Frame Options and Materials
What frame materials do you offer?
We offer four frame material options: uPVC (our best value option), aluminium, timber, and composite (aluminium and timber combination). Each material has unique benefits, and our team can help you choose the best option for your aesthetic preferences, budget, and performance requirements.
What are the benefits of uPVC windows?
uPVC windows offer exceptional value with superior durability, safety, energy efficiency, and sound reduction at an affordable price. They are 100% recyclable, multi-chambered with steel reinforcement, available in many colours, and will not fade, warp, chip, or peel. They’re also flame retardant and rated up to BAL-29 for bushfire zones. Discover more about uPVC windows.
Are your windows customisable?
Yes, all our windows and doors are custom-made to your specifications. We can accommodate various shapes including angles, arches, and specialised designs. We also offer multiple colour options and can incorporate features like colonial bars to match your home’s architectural style. View our gallery for inspiration.
Security and Safety
How secure are Oknalux windows and doors?
Our windows and doors feature award-winning MACO multi-locking hardware, recognised globally for durability and safety. When locked, the multi-point locking system secures the sash tightly to the frame. All systems include anti-burglary fittings that prevent external tampering, even when windows are open in the tilt position. Learn more about our safety features.
Are your windows rated for bushfire zones?
Yes, our uPVC windows are classified up to BAL-29 (Bushfire Attack Level 29) due to their steel reinforcement and self-extinguishing properties. The uPVC material has inherent flame retardant properties and will not support combustion.
What type of glass do you use?
We use low-E (low emissivity) glass as standard, which improves thermal performance by reflecting heat. We also offer various glass types including acoustic glass for enhanced noise reduction, tinted glass, and different thickness options depending on your specific requirements.
Installation and Warranty
Do you provide installation services?
Yes, we provide professional installation services throughout our service areas in NSW, SA, and ACT. Our experienced installers are respectful of your property and ensure proper fitting for optimal performance and longevity. Read what our customers say in our testimonials.
What warranties do you offer?
We provide a lifetime warranty on glazing and a 10-year warranty on frames. Our products are manufactured using advanced European technology with quality materials designed for the Australian market, ensuring long-term performance and reliability.
Can you retrofit double glazing to existing windows?
Yes, we offer retrofit double glazing solutions for existing window frames. This can be a cost-effective option for improving your home’s energy efficiency without complete window replacement. Contact us for an assessment to determine if your existing frames are suitable for retrofitting.
Technical and Performance
What is argon gas and why is it used?
Argon gas is an inert, non-toxic gas used to fill the cavity between glass panes in our windows. It is denser than air, which reduces heat transfer and improves the window’s insulating properties, enhancing overall energy efficiency and thermal performance. Learn more in our article about what is argon gas.
What does ‘draught-proof’ mean?
Our windows are 100% draught-proof thanks to rubber seals (instead of brush seals) that create a completely tight system when closed. This prevents air leakage and heat flow through window sashes, eliminating uncomfortable draughts and improving energy efficiency. Read about overcoming draughts.
What is a thermally broken frame?
A thermally broken frame includes an insulating barrier within the frame structure that prevents heat transfer through the frame material. Combined with multi-chambered construction, this technology ensures the frame performs as efficiently as the glazing itself. View our technical information for more details.
What is the U-value?
The U-value measures how well a window prevents heat from escaping. Lower U-values indicate better insulation. Our windows achieve some of the lowest U-values available in Australia, meaning superior thermal performance and energy savings. Learn more about thermal performance.
