For added peace of mind choose Sheerline aluminium windows and doors are available with a laminate glass upgrade – for Secured by Design accreditation – the official UK Police initiative ‘designing out crime’ through physical security. 

With unrivalled security built into the heart of every window. The innovative construction of the Classic window system eliminates the need for separate glazing beads – often an area of weakness in traditional window design. Instead our patented corner jointing method securely locks the glass away within a completely sealed unit. This coupled with our high security multipoint locking and unique hinge protectors creates unparalleled levels of security. No window in its class is as secure. 

All Sheerline windows carry PAS24:2016 enhanced security accreditation, so if you are looking for stylish aluminium windows with extra peace of mind as standard – then we have you covered. 

For added security choose our laminate glass upgrade – for Secured by Design accreditation – the official UK Police initiative ‘designing out crime’ through physical security. 

Thermal energy efficient

Outstanding thermal performance 

Thermlock® technology helps keep you and your home snug and warm. Cold, crisp lines on the outside hide away our innovative Thermlock® multi-chamber thermal design, helping keep you and your property well insulated against the worst of the UK weather. 

This closed-cell, insulating chamber acts as a thermal break and works in conjunction with our high performance double glazing to create class leading thermal performance, far superior to traditional polyamide thermal breaks. Sheerline’s cills also feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside.
