Sheerline Classic

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

The innovative construction of the Classic window system eliminates the need for separate glazing beads. These are often an area of weakness in traditional window design but our patented corner jointing method securely locks the glass away within a completely sealed unit.

With slim sightlines of just 59mm, it’s perfect for maximising the light flooding into your home.

Sheerline Classic windows achieve U-values of 1.4, whereas other aluminium windows regularly struggle to achieve the standard of 1.6. The better insulated a window is, the lower the U-value will be.

Sheerline Prestige

The Prestige window system has been carefully designed to combine stylish looks with the latest technical innovation. Sheerline Prestige incorporates many unique features to create an incredibly thermally efficient, secure system.

Sheerline Prestige windows achieve U-values as low as 1.3 (with double glazing) and 0.9 (with triple glazing). This helps to keep you and your home well insulated against the worse of the UK weather, whilst keeping energy bills down.
