INSULATED GLASS UNITS
WITH WARM EDGE
Until recently, aluminium spacer bars were widely used in the construction of IGUs. Aluminium is highly conductive and has an exceptionally high thermal energy loss.
With ever-improving window frames and glazing systems and an emphasis on thermal efficiency, the market has seen a huge switch to warm edge technology.
Reducing energy consumption is undoubtedly a must. This switch has resulted in the requirement for windows with increasingly lower thermal transmittance values, Uw [W/m2 K]. The warm edge used today in insulating glass units has played an important part in achieving these objectives.
