What sustainable window system technology is UK manufacturers adopting?
Warwick Development NW manufactures MODIS, a window system built with Neovan resin that reduces carbon footprint by 37 percent through electrification processes. It is arguably the most sustainable window system available on the UK market, engineered to help housing associations meet their goals of building energy-efficient, warm, and safe dwellings.
Neovan resin: electrification cuts carbon at source
The sustainability advantage of MODIS hinges entirely on its material foundation. Neovan resin is manufactured by the Inios Group using electrification processes that fundamentally reshape the carbon profile of window production. Instead of relying on conventional fossil fuel-based heating, electrified manufacturing switches energy inputs, allowing the resin to achieve a significantly lower carbon footprint from the moment it leaves the factory.
This 37 percent carbon reduction matters most in sectors where environmental performance is not optional. As Greg Johnson explains in the Glazing Insider podcast, the window system has become a direct response to the growing demands of housing associations and registered providers who are building and refurbishing social housing under strict sustainability criteria.
Alignment with housing standards and regulatory pressure
The adoption of MODIS reflects a broader shift in UK construction and social housing delivery. Government spending on social and affordable housing has made energy efficiency and carbon reduction non-negotiable, and window manufacturers who can prove measurable environmental gains gain a competitive edge with major institutional clients.
Energy-efficient windows do more than reduce operational heating costs for residents; they contribute to achieving warm, safe homes — a core social value goal. For a company like Warwick Development NW, operating as the largest window manufacturer in the Liverpool City region and serving a wide network of housing partners, offering a system backed by certified carbon reductions becomes both a market differentiator and a fulfillment of their social mandate. Discover how Warwick partners with housing associations to embed social value into window manufacturing and how this shapes their product strategy beyond sustainability metrics alone.
"We make windows and doors, but if we can use our platform as a business to give back and make a difference to our local communities, then I think that's the winning formula."
