BREAKTHROUGH TRIPLE GLAZING PROJECT LEADS LUTLEY WINDOWS TO CHOOSING REHAU
Double glazing installation and repair window fabricator , Lutley Windows , now exclusively uses REHAU profiles following a successful , ground-breaking project with housing association , Midland Heart , last year .
Adopting an incremental approach to improving the energy efficiency of their homes , housing provider Midland Heart has been exploring how their existing practices may be supplemented by innovative technologies and new methods . In doing so , the organisation identified an opportunity to complete a triple glazing installation , in collaboration with existing supplier , Lutley Windows .
Lutley Windows was established in 2014 by Mark Taylor , director and owner of the business . Based in Wednesbury , West Midlands , the 30-strong team specialises in fabricating and installing a wide variety of quality double glazing products for residential properties .
After being asked by Midland Heart about the potential of fabricating triple glazed windows for a collection of homes in need of EPC upgrades , Lutley Windows swiftly approached REHAU about the potential feasibility of the project .
A key requirement was that the windows had to achieve a U-value of 0.8W / m 2 K . This was to be in line with the government ’ s Future Homes Standard regulation coming into force from 2025 . With Mark finding that his existing suppliers ’ profiles couldn ’ t meet the target , Luke Boban , Area Sales Manager at REHAU , stepped in to advise Mark on the specification for the windows . Following a bespoke design and extensive modelling of the thermal transmittance , REHAU ’ s T70c 52mm profiles were chosen for the first-of-its-kind project and delivered a U-value of just 0.81W / m 2 K . A total of five windows were fabricated and installed in a successful trial run at a tenant ’ s home in West Bromwich in May 2023 .
This industry and domestic housing has seen a further 139 properties receive energy efficient triple glazing part of ‘ business as usual ’ that pre-empts any external wall insulation ( EWI ) works required to get each home to net zero .
And this hasn ’ t stopped there . Learnings from the project have shown that to meet
Before
net zero by 2050 , the frame size needed to be further enhanced to 72mm and drip innovation added , and the product has since evolved to achieve this target and meet future external and internal wall insulation requirements .
Together Midland Heart , Lutley Windows and frame manufacturer REHAU are leading the sector to make triple glazing an affordable retrofit measure to support the Government ’ s EPC targets .
