It is in most cases over 25% better insulated than our rivals 36mm triple glazing. 44mm triple glazing offers a centre pane U-value of around 0.6. This type of window offers over 40% better insulation than our "A" rated double glazing. When we only used single glazing, windows had a U-value in excess of 5, early double glazing reduced this figure to 3, but over the years the u-value on double glazed units has dropped to around 1.1, with the introduction of warm edge spacers, argon gas and low-e glass. Over time U-values in windows have dropped. The method of comparing the energy performance of windows is to use the U-Value, as used when comparing walls, roofs and floors. What is the u-value of triple glazed windows?īuilding regulations are becoming more stringent regarding thermally efficiency.

EdgeGardMAX state-of-the-art window spacers provide superior insulating properties with an advanced design to help stop heat flow and reduce condensation. Too much or too little air space can affect the insulating glass efficiency.ĮdgeGardMAX® Spacers - Traditional aluminum box spacers use desiccant and sealant between two panes of glass to provide insulation. Spacers – A spacer keeps a window’s dual glass panes the correct distance apart for optimal insulation between panes. It also offers more light transmittance and less reflectance than triple glazing. 4th Surface provides energy performance levels in a Dual Glazed insulated unit that previously were only attainable with our Triple Glazing option. It’s a durable TCO (Transparent Conductive Oxide) coating that enhances the U-factor of the window by reflecting heat back into the home. Milgard SunCoat is Low-E2 and SunCoatMAX is Low-E3 giving you better levels of protection.Ĥth Surface - 4th Surface turns double-pane windows into triple-pane performers. Carpet and furniture are also better protected against UV rays and color fading. As a result, homes with Low-E glass windows and doors enjoy more consistent temperatures year-round for comfort and energy savings. A thin coating is applied to one side of the glass to reflect heat toward the outside in the summer and keep heat inside the building in the winter. Glass coating technology has helped create more energy efficient windows. SunCoat® and SunCoatMAX® Low-E Glass Coatings - Low-E means ‘low emissivity’ and describes glass that has a solar control coating to improve thermal performance. Triple glazing adds a third layer of glass that improves insulating properties, keeping homes in northern regions warmer. Energy efficient windows use dual or triple pane glass (or glazing) to better insulate and help reduce energy usage in the winter and protect against heat build-up during the summer. Dual and Triple Glazing - Many older windows were built with a single pane of glass.
