Our most thermally efficient and versatile 72 – 80mm wide system, is available in casement, French, tilt & turn and fixed window styles, and has been designed to be sympathetic to the modern trend for light, airy interiors. Using slim sashes allows more light to flood into homes, helping create that important sense of space and tranquillity.

Patented Construction 

Our patented construction method – using threaded screws to bind corners tightly together – helps eliminate misaligned corner issues that can occur on ordinary aluminium frames. This allows each Sheerline window to be individually hand tuned to perfection. Leaving you with the perfect balance of understated refinement coupled to exacting quality standards, where no detail’s overlooked.

Inbuilt Security 

Prestige’s full depth eurogroove also enables us to offer the latest high security, multipoint locking – helping keep homes safe and secure. Additional features like unique hinge protectors also help create exceptional levels of security. For added peace of mind choose our laminate glass upgrade – for Secured by Design accreditation –the official UK Police initiative ‘designing out crime’ through physical security.

Our innovative Thermlock^®  multi-chamber thermal design, hidden away inside each window and door, helps keep properties well insulated against the worst of the UK weather. These closed-cell, insulating chambers act as a thermal break and work in conjunction with high performance glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks.
