Home window fabricator

Winner: Wakefield Metroglaze

Sponsored by: The Installer

The judges were impressed not only by the energy saving aspect of this project but also by the innovation in eliminating the spend and waste associated with complete replacement, whilst still achieving desirable U-values.

Metroglaze up-graded 20year-old single glazed windows in properties belonging to Wakefield District Housing who considered the existing PVC-U outer frames still to be sound and so only requiring the sashes to be replaced.

This caused the minimum inconvenience to residents. The plan is to bring 1,500 homes up to current Building Regulations by improving the thermal performance of the windows – with 25 homes per week being improved.

There has been a considerable improvement with the enhancement of centre pane U-values from 5.9 to 1.2, simply with the change from single float glass to double glazed units with diamant, warm edge spacers, argon and Planitherm total +.
