A window is a whole. Its glass is particularly important, but the frame and sashes and the materials they are made from, or details like argon gas filling in double glazing, warm edge spaces (to reduce thermal bridging at the edges of the window), thermal breaks (for high conductive materials like aluminum) and insulated frames (the hollow sections of the frame and sash can be filled with foam insulation to increase the energy efficiency of the window) are also crucial.
Windows, simply put, are made up from glass and the frame that holds that glass. Window frames and sashes can be manufactured from a variety of materials – wood, aluminum, vinyl (UPVC), or a combination of these materials (Composite Windows), all of which have implications in the thermal efficiency, durability, environmental impact and costs of the windows.
For now we shall concentrate on Wood, Aluminium and Composite Windows in the information to be published soon. In the meantime, get in touch with us for advice.
