A total of 113 Stellar aluminium flush casement windows have been manufactured and installed in the refurbishment of North East Surrey College of Technology (Nescot) in Epsom, Surrey.

The vocational FE and HE college had funds to replace the original timber and aluminium windows in one of its 1980s-built buildings. Upgrading the windows would enhance thermal efficiency, as well as improving the visual appearance of the building.

The college appointed Chawton Hill Associates to manage the refurbishment project. The contract for the fabrication and installation of the windows was awarded to Epwin Window Systems’ approved commercial partner, Capital Windows of Uxbridge, due to the company’s high-level commercial credentials which aligned with Chawton Hill’s expectations.

Stellar aluminium flush casement windows were specified for the project because they were able to meet or exceed the specification, including meeting the requirements of the Department for Education’s Standards for School Premises.

The 113 Stellar windows were manufactured to achieve a U-value of 1.4 W/m²K using a standard 6.4mm clear laminated outer pane, 16mm or 12mm black spacer with argon and 6.4mm soft coat low-e laminated inner pane. Solar glass was used in the windows for the building’s south elevation to prevent solar gain and glare.

To complement the building’s aesthetics, the project’s windows were powder coated in anthracite grey (RAL 7016 matt) on both sides. Matching fascias and soffits were also specified for a high-quality visual appearance.

Peter Adams, general manager at Capital Windows, said: “Stellar has cross-sector appeal because of its combination of exceptional aesthetics and outstanding thermal efficiency. It was the perfect system solution for this project.”

The installation of the windows was undertaken during term time, which meant careful planning to minimise disruption to students’ learning. The work was carefully sequenced week-by-week, with stringent health and safety protocols in place to ensure the safety of students, staff and contractors.
