Sheerframe window solution beats housing upgrade challenge

Wakefield District Housing (WDH) ‘Winget’ properties on Wakefield’s Lupset Estate which have been transformed by an innovative window replacement project using Sheerframe casements to upgrade the existing Sheerframe outer-frames.
More than 20 years since first generation Sheerframe windows from LB Plastics were fitted into hundreds of Wakefield District Housing (WDH) properties, the forward thinking social housing provider has found a cost effective solution to improving the thermal efficiency of 1500 homes – simply by replacing the casements but leaving in place the Sheerframe outer frames.
The original single-glazed Sheerframe windows fabricated and installed 20 years ago by social housing fenestration specialist Wakefield Metroglaze largely retain their integrity meaning only the opening lights - plus glazed units in some fixed lights - require replacement to meet today’s Building Regulations.
In addition to the thermal and aesthetic benefits, this upgrade approach also minimises the disruption which full replacement might bring, reducing inconvenience for householders.
Originally built in the 1920s and 30s, the precast reinforced concrete (PRC) Winget houses on the Lupset estate began presenting significant structural and performance problems by the 1980s. At this time Wakefield council invested in a major overhaul of the houses, including external wall insulation which increased the overall depth of the envelope and new windows.
Wakefield Metroglaze is completing the window upgrading at a rate of 25 properties per week and has so far completed more than 200 homes.
The new casements are created with the latest Sheerframe PVC profile system which is multi-chambered for superior resistance to heat loss to deliver windows with a low whole window U-value.
