The best energy efficient windows have Swisspacer bars

Spacer bars which conduct less heat at the edge of the glass are referred to as 'warm edge spacer'

The benefits are as follows:

  • Reduced heat loss through windows
  • Condensation on windows can be reduced
  • Better sound insulation
  • Argon Gas filled sealed units

Filling the gap between the panes increases the thermal performance of insulating glazing units is to reduce the conductance of the air space between the layers. Originally, the space was filled with air or flushed with dry nitrogen just prior to sealing. In a sealed glass insulating unit, air currents between the two panes of glazing carry heat to the top of the unit and settle into cold pools at the bottom. Filling the space with a less conductive, slow-moving gas minimises the convection currents within the space, conduction through the gas is reduced, and the overall transfer of heat between the inside and outside decreases.

Low-E Glass

High-performance Low-E (low emissivity) glass is designed to reduce heat loss and must be used on energy rated windows. There are two types of low e glass, Hard Coat and Soft Coat, we use soft coat glass as it gives the following benefits over hard coat:

Better light transmission
Better U-Values
Enhanced clarity/neutrality.
Low Iron Glass

By reducing the amount of iron in the external pane of glass, the solar gain of the window is improved. KJM's 'A'-rated windows have this as standard.

Triple Glazing

When this web page was first written, we did not sell 44mm triple glazed windows & doors. Today we can improve on our best rated double glazing by over 40% with our Veka triple glazed range. You can find out more information on our blog page triple glazed windows.

If you have old uPVC windows, then they are probably very energy inefficient. Modern 'A' rated windows offer considerably better insulation and more secure locking mechanisms. See our free brochure download Replacing your old uPVC windows
