Ultra-Secure, Ultra-Slim Beadless Windows

Sheerline Classic Aluminium Windows

Introducing Sheerline Classic windows, designed to be the most secure, elegant and environmentally friendly aluminium system available.

The innovative construction of the Classic window system eliminates the need for separate glazing beads. This is often an area of weakness in a traditional window design. The patented corner joints securely lock the glass inside, encasing it in a sealed unit.

These windows achieve a U-value of 1.4-The better insulated a window is, the lower the U-value will be. Other aluminium windows typically achieve a U-value of 1.6.

Styling Options

With a choice of contemporary or traditional styling, Sheerline windows are available in two sash styles; stepped and contemporary.
Both styles are available in either our standard outer frame or as a ‘flush’ option that brings both the perimeter and the opening sash perfectly in line with each other.

Georgian bar options are also available.
