Warm edge products aim to minimize this energy loss. Warm Edge Technology refers to the edge construction of a double glazed unit that conducts less heat or cold than traditional windows and standard construction double glazed units.
Standard double glazed 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 of 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 at the external edge of your window.
While making a real contribution to the environment, this heat loss saving can help to reduce the heat consumption of a home which lowers carbon emissions and saves money on fuel bills.
Warm edge technology can also help to reduced 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.
