It also provides exceptional security, meeting PAS 24: 2022 as standard.

Introducing Stellar – the multi-award-winning aluminium window and door system with the most innovative design features on the market. The Stellar aluminium window and door system is an adaptable system with exceptionally slim sections, excellent performance and a high-quality finish. Every individual window or door is a bespoke product, tailored to your precise specification and needs, but every part of the range delivers on the Stellar Promise.

Stellar also boasts a unique advantage. Its reverse butt joint ensures Stellar can always be glazed from the inside. Other systems rely on dummy window sashes, an approach which adds expense and compromises style, but Stellar’s patented solution ensures it has both the security you want and outstanding aesthetics.

Stellar consumes less material than other systems, can reach Band A++ thermal performance and is responsibly produced with a Green Guide A rating.
