Choosing the right windows for your home is an important decision. An investment that makes a real difference to how warm and secure you feel; as well as changing the look of your property. This is why we have designed the Classic system from the ground up. Building on years of experience, we’ve incorporated many new innovative ideas; creating a warmer, slimmer and more secure window system. Designed for discerning homeowners that aren’t willing to compromise, our windows are tailored to those who demand more for their home. Built around an innovative

Thermlock® multi-chamber thermal break, our windows use a patented construction method that offers unsurpassed levels of security. Creating windows that are strong and durable, yet with slim frames that maximise the light flooding into your home. Sheerline aluminium windows are also available in a wide range of colours, letting you express your home’s character

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

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 sills also feature this same technology coupled with innovative in-built weather sealing that keep draughts and rain safely outside

With great looks from every angle - due to our unique construction method. The ultra slim 59mm sightlines of the innovative Classic window system maximises the light flooding into your home, creating a refined architectural look. While our patented construction method – using threaded screws to bind corners tightly together in perfect unison – creates perfect run through mitres on internal joints, doing away with the unsightly junctions of square cut beads seen on ordinary aluminium windows

We’ve also designed out the stepping of misaligned corners, allowing each Sheerline window to be individually hand tuned to perfection. Leaving you with the perfect balance of understated refinement and exacting quality standards
