Sustainable by design – Roundbrand installing Zero|90 in over 200 homes at Bennerley View.

As sustainability moves from a value-add to a requirement in the UK housebuilding sector, fabricator-installer Roundbrand Ltd is helping developers meet the challenge with cutting-edge solutions - none more impactful than Liniar’s Passivhaus-capable Zero|90 window and door system. 

With U-values as low as 0.66 W/m²K, Zero|90 sets a benchmark in energy performance for PVCu systems, and Roundbrand is proudly deploying it at scale. At Avant Homes’ Bennerley View development, the company is installing windows and doors from the range on over 200 plots, supporting the site’s aim to exceed expected Future Homes Standard requirements.

Matthew Williams, a Director at Roundbrand, says, “Zero|90 gives us a major edge. Its U-value performance leads the market. For developers looking to futureproof their builds, it’s a compelling solution, and we’re proud to be fitting it at volume.”

Technical performance that builds confidence

Roundbrand’s strategic alignment with Liniar, particularly on low-carbon product innovation is helping the business deliver exceptional value to developers.

“We’re seeing growing demand for advanced thermal performance, especially from forward-thinking developers,” says Matthew. “We supply the entire Liniar range, but the standout technical performance of Zero|90 is allowing us to help our clients meet and even exceed environmental and regulatory benchmarks needed for the UK’s target of a Net Zero future.

“Besides its phenomenal energy performance, Zero|90 is tested to BS PAS 24 security standards and Secured by Design certified. The profile’s additional chambers, accommodated by the 90mm width, also mean it can reduce noise levels by up 42 decibels, while maintaining the same slim sightlines as a 70mm system. The complete package offers specifications desired by developers with the comfort, security and style desired by homeowners – a winning combination!”

Sustainability meets quality at Bennerly View

The Bennerley View site in Awsworth, Nottinghamshire exemplifies the shift toward high-spec, sustainable new builds - featuring solar PV, EV charging points, and thermally superior construction. 

“The development required a window and door solution that matched its low carbon ambitions, and we recommended Zero|90 complete with low-e triple glazing,” explains Mathew.

He continues, “It’s not just the impressive U-values, the entire system is engineered for long-term performance, from weather protection to strength. The most reputable developers are ensuring adherence to the New Homes Quality Code, and because we fabricate and install each finished window and doors ourselves, even down to the glazing units, Roundbrand customers get full assurance on quality and continuity.”

Gaining momentum in the new-build sector

Roundbrand’s project management experience spans national builders (250+ plots) to smaller developers (4-10 plots) and all types of accommodation from apartments to luxury homes. Across the board, its ability to deliver a scalable, energy-efficient fenestration package, combined with rapid customer care resolution via its in-house aftercare team, has become a key differentiator.

Mathew concludes, “At Roundbrand we’ve establish logistical infrastructure, manufacturing capacity, and strong supply partnerships. By aligning with developers’ ambitions and championing next-generation window and door systems such as Zero|90, we’re not just meeting the demands of today, we’re setting the standard for tomorrow with a fully supported end-to-end customer experience.”
