Double Glazed Windows Melbourne
Upgrade your existing timber windows with high performance double glazed glass to improve energy efficiency, lower the carbon footprint of your home and save money!
What are Double Glazed Windows?
Double glazed windows are high performance window units that consist of two panes of glass that are separated by an air, gas or vacuum gap between 0.3mm to 20mm in width. This gap between the two panes of glass increases the energy efficiency of the window and can reduce household energy usage by up to 60%.
Advantages of Double Glazed Windows
Double glazed windows provide a range of advantages compared to single glazed windows:
Enhanced insulation
Double glazed windows improve the insulative properties of your home by creating a thermal barrier between the inside of your home and external weather conditions. The sealed air, gas or vacuum gap technology slows heat transfer and helps to keep your home warmer in winter and cooler in summer.
Energy bill savings
Double glazing your windows helps to reduce energy bills as more stable home temperature helps you to cut back on heating or air conditioning. This can help you to save money over the long-term
Improved security with tougher glass
With two panes of glass, double glazed windows are harder to break compared to single glazed windows. Our range includes toughened and thicker double glazed glass options.
Noise reduction by up to 70%
Double glazed windows can significantly reduce outside noise from traffic, neighbours or barking dogs as the dual glass layers and insulating air gap act as a sound barrier. So double glazing your windows can create a quieter and more peaceful home.
Reduction in condensation on windows
Condensation forms on windows when warm, moist air inside your home comes in contact with a cold surface, such as a window pane. Double glazed windows enable interior glass surfaces to maintain a more even and warmer temperature which reduces the chances of condensation and mold forming on windows.
Increased property value
Homebuyers view double glazed windows as a desirable feature when they are looking for a new home. A double glazed home appeals due to long term bill savings, increased home comfort and also the environmental and sustainability factors.
