168 Stellar Flush Casement Windows installed in a high-end London apartment block

Experienced Stellar fabricator and installer Capital Windows has just completed the manufacture and installation of 168 Stellar Flush Casement Windows as part of a complete commercial refurbishment of a prestigious private apartment block in a sought-after area of North London’s NW2.

The original crittal style windows of the red-brick apartment block had lost their aesthetic appeal and were poorly insulated. Stellar from Epwin Window Systems was selected to replace the windows because of the system’s high-end aesthetics and, more importantly, its ability to achieve the thermal requirements of Part L with standard double-glazed units.

The windows were manufactured in Anthracite Grey on both sides to give the building an updated aesthetic and sophisticated appeal. The project took 12 weeks from start to finish and has completely transformed the building’s appearance and thermal efficiency. Peter Adams, General Manager at Capital Windows, said: “This project is the perfect example of the transformational benefits of Stellar. The upgrade has helped to enhance the value of the apartments in the block and made them more comfortable to live in.”

Capital Windows of Uxbridge, Greater London works with domestic, trade and commercial sectors throughout the South-East of England. For over 40 years the company has positioned itself as a specialist designer, supplier and installer of the latest generation of technically advanced window and door products. It has been manufacturing Stellar, which it markets under the brand name Evoke, since 2020. Peter said: “We were an early adopter of the Stellar aluminium system as we were impressed with the unique flush aesthetics which has been instrumental in securing several large-scale domestic contracts. However, the thermal performance of Stellar is second to none, and as a result, we have won several commercial projects as the system easily complies with Part L of Building Regulations without complicated workarounds.”

The multi-award-winning Stellar from Epwin Window Systems was predominantly designed for the domestic market, but since the changes to Part L of Building Regulations last year, it has been rapidly gaining traction across commercial projects. This is because the system features the patented reverse butt joint, which means no dummy sashes or reverse adaptor profiles are needed. This makes it thermally efficient by design and means it can achieve the requirements of Part L in double glazed versions without the need for complicated workarounds that add extra time and cost.

Peter concluded: “Stellar has always been a very easy system to sell into the domestic market because of its outstanding aesthetics. The innovation in the design means it is now an easy system to sell into the commercial sector too. We are looking forward to securing more commercial projects using its powerful benefits.”
