Cold Climate Glazing: Glass Choices To Keep You Warm


Victoria, New South Wales and Tasmania have seen the coldest and most brutal start to winter in years.

Victoria's alpine regions have seen huge dumps of snow, while Sydney shivered through its coldest start to winter in more than 30 years. 

If you're looking to warm up your home in the current cold snap - you should look at your windows first. 

Even though windows typically account for only 10% of the total surface area of your home, they can account for as much as 50% of total heat loss in winter. 

When planning or renovating your new home, there are some things that you should take into consideration with regards to your windows if you live in a cold climate.  

Window Considerations For A Warmer House 

  • Use double glazing or Low-e glass to help keep the temperature within the home more consistent (less heat gain in summer and less heat loss in winter.) Double glazed windows can improve your home efficiency by as much as 40%.
  • Exploit and optimise Solar Heat Gain (SHGCw), that is select a window with a higher SHGCw to allow more solar radiation to pass through and heat your home.
  • Select a window with a lower U-value for greater energy efficiency. 


When deciding on the right glass for your climate, you cant beat talking to an expert.
