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 is a high-performance aluminium system for windows and doors. It’s extraordinary because its designers were given a clear brief: to produce the best aluminium system for the UK’s homeowners.By refusing to compromise, a remarkable system has been developed. Its sightlines are significantly slimmer than other aluminium glazing systems. The improved glass-to-frame ratio creates homes that are brighter, lighter and more beautiful.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 patent-pending 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.
