What Makes a Window Energy Efficient?

One of the key methods to tell if energy efficient windows work is their insulation qualities. Whether your home can stand up against heat, cold temperatures and wind strength; there are common factors that you can also look out for regarding a window’s efficiency:


U-values are a measurement to reveal the overall efficiency of your home, influenced by your product. In this case, windows with triple glazing can reach U-values from 0.8-1.6W/m2k, which is outstanding. The lower the U-value, the better, so getting the ideal glazing for your home really can benefit you in the long run.

Gas Fills

Double and triple glazed windows often have gas trapped between the panes, usually argon or krypton gas. These gases work as insulators against heat transfer; since these gases are odourless, transparent and non-toxic, your home can work with you to create the perfect energy efficient window. Additionally, the more glass panes, the most gas layers there will be for cold air to pass through – you can truly take advantage of your Internorm experience.
