      Installation of windows - Useful tips and information

      Improper installation of windows and doors may lead to a great energy loss during heating or cooling, because even tiny cracks let the heated or cooled air escape, although you paid for it. This movement of air around windows and doors is called a thermal bridge. What’s more, thermal bridges also allow dust, mould, and damp into a house. The basic rule when installing a window is placing it along the outer edge of the wall, as this minimizes the likelihood of thermal bridging. In traditional window installation, cracks between the wall and frame are filled with spray foam, but it doesn’t stop movement of air completely. Today, the RAL system, a German standard for professional door and window installation, has become a must with all new builds. The RAL installation applies state-of-the-art technology and top-notch materials according to defined instructions, which enables maximum saving of energy. The most important thing is to prepare the opening thoroughly, make it even and completely dry, and then take all steps to prevent water and damp ingress through the space between the wall and window. A window should be installed along the centre line of a wall. If cracks are properly sealed by means of spray foam, a membrane, and sealing tapes, energy loss is minimized. Spray foam is used to seal cracks between the wall and window, while special membranes are applied from the outside and from the inside; the former should let air pass through, but hold vapour, and the latter should block both water and vapour. This helps prevent condensation and its adverse results, which in turn creates optimal living conditions, comfort, and energy efficiency. Finally, you should also consider installing interior and exterior window sills, blinds and other shading solutions.
