Sheerline’s Prestige Range Transforms Council Building as Part of Thermal Upgrade Scheme

The installation of Sheerline’s Secured by Design (SBD) accredited Prestige windows and doors has helped Swale Borough Council improve its thermal efficiency as part of its cost and energy saving Thermal Upgrade Scheme. The project has been completed in conjunction with Swan Doors and Windows and Waller Associates.

One of the key objectives of the project was to improve the overall thermal efficiency and therefore lower the carbon footprint of the building. Targets such as this are gaining importance as businesses and organisations look to reduce their energy costs and the UK government works towards its Net Zero Strategy.

Taking place at Swale House, the council’s head office, the works were completed in stages to minimise disruption to employees and due to the large scope of the project. The key aim was to replace the poorly performing single-glazed windows, which were original to the offices (built in 1984).

The Sheerline system was recommended for the project because the company met the three specific requirements: a robust aluminium system, excellent thermal properties, and short lead times. Swan Doors and Windows fabricated and delivered all the windows for this project.

To upgrade the appearance of the building, the council opted for Sheerline’s Prestige windows in Anthracite Grey (RAL 7016). This contemporary colour choice is one of the most popular because of its versatility and ability to enhance the look of most properties and buildings.

Paul Ewart, Director, Swan Doors & Windows, commented: “The Sheerline Prestige range of windows is a robust aluminium system with great thermal efficiency, which ultimately helps the planet and will save on energy costs for years to come.

“What we especially like about Sheerline’s products is the method of mechanically joining the profiles, the low U-values and the use of standard hardware,” he added.

Waller Associates successfully won several project elements through a competitive tender process, including the installation of the windows. The company installed anti-solar glass on every south-facing window to prevent glare and reflect sunlight, which is useful for those who work at a computer. This approach will also prevent the office from overheating during hot summer months.

A representative from Waller Associates commented: “The council is extremely pleased with the new windows, and they look great. In addition, they have dramatically improved thermal efficiency, which means the heating will not be used as much – the benefit of this is lower energy costs in the future.”

This is the second time Sheerline, Swan Doors and Windows, and Wallers Associates have collaborated to transform a building in the South East. The companies previously worked together to transform a large grammar school in Kent.

Sheerline’s CEO, Roger Hartshorn, comments: “The fact Sheerline was recommended and then selected for this project shows we’ve got the formula right. From the very beginning, we understood the need for a stylish, secure, yet thermally efficient aluminium system. But we also value our installer and fabricator partners and wanted to make life easier for them. The positive feedback from this project proves we’ve achieved this.

“It’s always a pleasure working with Swan Doors – as one of our trusted partners, we can depend on them to complete every job to a high standard. We look forward to working with them on many more successful projects in the future,” he added.
