Add the finishing touches
While the classic style and slick functionality of our aluminium windows and doors will really complement your home, we know that security will always be a priority – that is why we aim to achieve Secured by Design certification on our products.
Delivering safety and security doesn’t mean any sacrifice to style and function though. We complement our ranges with hardware fittings that as well as operating efficiently remain tactile and pleasurable to use, and of course, beautiful to behold.
Every element of our hardware is impeccably designed, engineered and undergoes rigorous testing that includes lifetime use simulation.
That means fine, robust engineering allied to sleek, understated style. Under the surface, the rollers, bogeys, seals and brushes, contribute to smooth, efficient operation while the handles, locks and hinges integrate seamlessly with styles and colours to contrast with or precisely match your chosen application.
