Energy Efficient Triple Glazing Windows


Barnsbury Joinery are at the forefront of modern energy-optimised windows and doors. With high-performance 52mm triple glazing provided as standard, Barnsbury Joinery windows achieve U values as low as 0.97, which is ideal for low energy buildings and passive house construction. 


All triple-glazed units are constructed with argon gas insulation between the panes and a warm edge spacer or ‘thermal break’, which reduces heat loss round the perimeter of the window. In fact, our energy-optimised glazing can let in more free solar heat than is lost through the window, which significantly reduces the energy consumption required to heat your home during the winter.

Triple glazing also offers huge energy reductions in your home. By changing all the windows, even in a well insulated house from single glazing to triple glazing could save over £175 per year on energy bills.


Benefits of energy efficient windows:

  • Smaller energy bills

  • Smaller carbon footprint 

  • More comfort in your home

  • Noise reduction
