Double Glazing Existing Timber Windows
Double glazing existing timber windows is an ideal way to improve the energy efficiency of your home. In Sydney, where summers can be hot and humid, double glazing timber windows helps reduce heat transfer to the interior of your home. It also reduces external noise, making your home more peaceful and comfortable.
* Note: While double glazing is popular, we don’t normally recommend this for timber heritage windows – the reason it may only last 10-15 years, it can potentially leak, it is expensive and you have throw out the old window frames so it’s not as sustainable as other options. We advise under no circumstances to not do double glazing – we always do VIG or ComfortHush – Contact our team to get our recommendation for your situation. *
If you have existing windows in your home, there are several options available to you when it comes to double-glazing them. Timber windows, in particular, can be retrofitted with a secondary layer of glass, which is both energy-efficient and aesthetically pleasing.
Inner West Window Specialists can provide you with a wide range of double-glazing solutions for your existing timber windows. Every double-glazed unit is custom-built to the exact specifications of your window, ensuring a perfect fit and superior performance.
Double Glazing Existing Windows: How It Works
Double glazing works by creating an air gap between two panes of glass. This creates a layer of insulation which helps to keep the heat in or out of your home. The air gap also reduces noise from outside, making it easier to enjoy peace and quiet in your home.
Here’s what double-glazing existing timber windows involves:
Removing the existing window frames and glass
Installing a special double-glazing system with two separate frames
Fitting the new frames with a layer of energy-efficient double-glazing glass
Sealing everything to ensure an airtight fit and reduce heat transfer
At Inner West Window Specialists, we use only the highest-quality materials for our double-glazing installations. This means you can be sure that your existing timber windows will be energy-efficient and safe for many years to come.
