Our roof windows deliver outstanding energy efficiency
Thanks to their slim frames, large pane area and VELUX ThermoTechnology™ , our roof windows bring more daylight and warmth into your home than ever before. We are using high performance materials in the window construction that improves the insulation and air tightness.
You can improve your energy balance even more by selecting one of our low energy glazings/panes which are available for all types of our roof windows. You will have the option to select such a pane when configuring your own VELUX Roof WIndow.
