Boost natural light

Modern and sleek, Sheerline Classic aluminium windows are the most innovative beadless aluminium window on the market. With thin 59mm sightlines, Sheerline aluminium frames use a patented construction method that does away with the unsightly square-cut beads seen on other windows, creating beautiful run through mitres on corners, ensuring window frames are slim, yet strong, allowing daylight to stream into your home.

Not only that, Sheerline has designed out the stepping of misaligned corners, allowing each aluminium frame to be individually hand-tuned to ensure a streamlined finish in a choice of 12 powder-coated and anodised colours, with dual and bespoke colours also available.

Offered in stepped and flat-faced contemporary styles. Sheerline’s Classic windows are a Flush design – where the outer frame and opening sash of the window are perfectly inline, creating a sleek modern look.

Feel safe and secure

While looks are important so is security. Thanks to their unique beadless system, Sheerline Classic aluminium windows boast unparalleled safety – in fact, no other aluminium window in its class is as secure.

While separate glazing beads in traditional glazing are often an area of weakness, Sheerline has patented a corner jointing method that securely seals and locks the glass away. Furthermore, high-security multipoint locking and hinge protectors all contribute to the design’s PAS24:2016 enhanced security accreditation.

Why slim means snug

The cool, crisp lines of slim aluminium window frames are also adept at keeping warmth inside the home. In fact, Sheerline’s Classic aluminium frames feature an innovative Thermlock® multi-chamber thermal design to keep your property perfectly insulated against the worst of the British weather. Moreover, the windowsills feature the same technology plus an additional weather seal to keep draughts and rain safely on the outside.

Is the protection of the environment high up your agenda? It’s worth knowing that aluminium is the world’s most recycled and abundant metal in the earth’s crust. In addition, Sheerline’s aluminium windows are made in the UK in the most sustainable way possible on a state-of-the-art energy-efficient press.
