Insulating Glass Sealants
Windows are one of the most significant areas of a building where warmth is lost - an average house can lose up to 30 per cent of its heat through poorly insulated windows. Improving thermal efficiency allows not only to provide a more comfortable environment, but also to reduce the energy necessary to keep a building warm.
