First project for Modus by Listers

Modus by Listers has been specified on an 87-plot newbuild development in Essex, thanks to its low U-values and slim sightlines.

Approximately 700 Modus windows, in a mixture of white and coloured foils, will be manufactured by Listers and installed by Allglass (Anglia) for a local housebuilder over a 14-month period beginning in December 2023. Listers’ Gallery 44 composite doors in a variety of colours will also be installed.

Modus was originally chosen because the local planning department stipulated that they had to achieve 0.8W/m2K U-values, which is a Passive House level of performance.

“As a company, we keep a close eye on industry developments, and we are already talking to our suppliers so that we can install windows into newbuild properties with U-values of 0.8W/m2K, when the Future Homes Standard comes into force,” saidAllglass’scontracts manager, Ben Friend.

“As a result, we were already talking to Listers about their new Modus window, which can achieve Passive House levels of performance with a triple glazed unit in a 75mm frame and a very slim rebate.”

Ben explained that after the products were specified, the planning department relaxed their requirements, and the windows only had to meet a 1.1W/m2K U-value.

“Fortunately, with Modus, we could achieve this with a double-glazed unit,” he said, “which meant we could save ourselves extra costs, as opposed to other products that would struggle to go below 1.2W/m2K without triple glazing.”

Modus By Listers is made using profile from Eurocell. Modus boasts a 75mm frame and sash that accommodates a premium 44mm triple glazed sealed unit. The system design has six equal thermal chambers delivering the optimum energy efficiency performance and can achieve a U-value of 0.8W/m2K.

Modus is available in Listers’ full colour range, including smooth foils, on competitive leads times.

Modus windows also contain between 36% and 72% of recycled materials in the profiles, reportedly helping it to achieve a lower carbon footprint than any other product made in the UK. Modus uses dual material extrusion technology, which layers post-consumer recycled and virgin material simultaneously – the recycled material is concentrated in the central core of the profiles, where it is completely invisible in an installed window or door.

A regular installer of EurocellLogik Windows, Allglass has been a Listers customer for eight years. The company supplies a range of projects from domestic refurbishment to newbuild, and from office blocks to schools.

“We work very closely with Listers, as we find that their values are closely aligned to ours,” Ben said. “They are always one step ahead of the regulations, and can offer good technical support.

“We’ve also started buying the Sheerline Lantern from Listers, which is a breeze to install, and can achieve lower U-values than many PVC-U alternatives.”
