Window Energy Ratings and Energy Efficiency
Many window companies will be trying to achieve high energy ratings to add to the quality of their overall product range and to offer consumers greater informed choices about the products they offer.
Window profiles are part of the story, but as glass makes up most of the area in a window, the components used in its construction are critical to achieving good levels of insulation.
