Energy Efficient Triple Glazing for Windows & Doors


Barnsbury Joinery are one of the leading experts in manufacturing and installing energy efficient triple glazed windows and doors. With high-performance triple glazing provided as standard, Barnsbury Joinery windows and doors achieve U values as low as 0.96, which is perfect for low energy building's and passive house construction. 


All the energy efficient triple-glazed units we manufacture 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 can also offer big financial savings in your home. By replacing all the windows and doors in your property, even in a well insulated house from single glazing to triple glazing could save up to £175 per year on energy bills.


Benefits of energy efficient Windows & Doors:

  • Reduction in energy bills

  • Reduction in carbon footprint 

  • More comfort in your home

  • Noise reduction
