Modus by Listers, the system introduced by the fabricator recently for its Future Homes Standards potential, has been specified on an 87-plot newbuild development in Essex.
Some 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. The company’s Gallery 44 composite doors will also be installed.
Modus was 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,” said Allglass Contracts 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 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.
