4Oct Energy-efficient windows by Robert Blog, Windows Energy-efficient windows Wondering how to retain heat energy, in your home or flat which will save you money on your bills? Fitting new windows is one solution that can help you improve your energy comfort, by better retaining heat in your home. You can then achieve significant energy savings... provided you choose your new windows carefully! GM PLAST can help you make the right choice. Importance of windows in energy comfort - On average, the windows of a house are responsible for 10 to 15% of heat loss. This means that 10 to 15% of heat generated by heating (electric radiators, gas heaters, boiler, wood cooker, etc.) is lost, thus reducing energy comfort. The impact on the quality of windows means that heat loss from the home is significantly reduced. The challenge is the same as for other energy renovation work: improving the insulation of the house to reduce energy consumption, maintaining optimum warmth in the house or flat, while reducing gas or electricity bills. It is worth knowing that In the ranking of causes of heat loss, windows are ranked 4th, just behind the roof and attic (the first cause of heat loss in a dwelling) and walls and air leaks. Our PVC windows have very good thermal insulation coefficients, which will allow you to reduce your energy costs by 10 to even 15 %. If you want to increase the thermal insulation coefficients more, we would then recommend the use of specially designed profiles, the so-called Passive House (Kommerling 88 MD) and triple glazing up to as much as 50 mm thick. The higher the level of glazing, the greater the promise of having a window with good thermal and energy insulation properties. If you want maximum energy comfort, it is better to choose a triple-glazed window model with an excellent thermal insulation coefficient Our PVC window profiles and their thermal insulation values Kommerling 76 AD High savings on energy costs - new 76 mm system with glazing gasket and highest thermal insulation values - Uw value for reference window up to 0.76 W / (m²K). Kommerling 76 MD High savings on energy costs - new 76 mm system with glazing gasket and highest thermal insulation values - Uw value for reference window up to 0.73 W / (m²K). Kommerling 88 MD Can be used for passive houses according to ift-Richtlinie WA-15/2 - Thermal insulation coefficient Uf=0.95 W/(m²K).
