Senior Architectural Systems is helping designers and housebuilders prepare for the forthcoming Future Homes Standard (FHS), with its aluminium window systems already engineered to meet the more stringent thermal performance requirements that will apply from 2028.
Published in March 2026, the updated Standard confirms a major shift in the way window performance must be assessed. Under the new Home Energy Model (HEM), whole‑window U‑values must be calculated for the exact configuration installed, replacing the previous approach that allowed the use of a standardised window. The maximum allowable U‑value for windows in new homes will also tighten from 1.6 W/m²K under current Part L to 1.2 W/m²K.
Senior’s patented PURe® aluminium window system is already designed to meet both current regulations and the new Future Homes Standard using double glazing, providing a straightforward route to compliance without the need for deeper profiles or triple‑glazed units. This performance advantage is delivered through PURe®’s unique PUR thermal break technology, which enables significantly lower whole‑window U‑values across a wide range of styles and configurations.
For projects requiring alternative aesthetics or specific design features, Senior also offers additional window systems including the slimline, heritage‑inspired Ali VU and the newly launched SPW+. Both can be specified in double or triple glazing to help meet project‑specific U‑value requirements, offering further flexibility for residential schemes.
Senior Architectural Systems’ specification support manager Karl Kovak said: “The Future Homes Standard provides much‑needed clarity for the industry, and window performance will play a central role in achieving the required outcomes. PURe® has been engineered from the outset to deliver long‑term, future‑proof thermal performance, and we are confident that our full range of aluminium window systems is well placed to support designers and housebuilders as they prepare for the transition.”
Senior is encouraging early engagement on new residential schemes, with full product information, technical resources and regional support available via its NBS Source profile and company website.
