Up to 80% of energy loss through a window occurs at its edge. Warm edge products aim to minimize this energy loss. Warm Edge Technology refers to the edge construction of a double, triple or quadruple glazed unit that conducts less heat or cold than traditional windows and standard construction glazed units. Standard glazed units or insulated glass sealed units are constructed with an aluminium spacer to hold the glass apart. However, aluminium is highly conductive and also has an exceptionally high thermal energy loss. Comparatively, double glazed windows fitted with warm edge spacer have a warmer internal edge temperature by up to 65% which helps to improve the thermal efficiency of the window and reduce the risk of condensation. Warm edge also significantly lowers the temperature differential between centre and edge of unit and up to 94% reduced heat loss (or heat gain) at the external edge of your window. While making a real contribution to the environment, this heat saving can help to reduce the heat consumption or air conditioning requirements of a home which lowers carbon emissions and saves money on fuel bills. Warm edge technology can also help to reduce condensation on your sealed unit by up to 70%. This reduction in moisture virtually eliminates the chance of mould growth and potentially harmful bacteria. This is an essential consideration for the increasing number of people who suffer from respiratory conditions such as asthma.
