The Ultimate Aluminium Window System

The BF73 system offers a versatile, slimline system for casement windows, sliding sash windows and slimline window frames.

Superior Aluminium Windows

Our slim aluminium window profile sections of the BF73 system minimise the visible framework and maximise the glass area, with sightlines of just 107mm from frame to sash. It offers one of the largest sash sizes available, up to 1200mm wide and 3000mm high per pane. The BF73 system also has part L compliant U-values as low as 1.4 W/m2K, DER Rating B, when combined with highly energy efficient glass. Also secure to PAS24.

All BF73 window sashes are available in 2 profile designs: square and textured square*. Choose square for a classic look or textured square for a more contemporary alternative.

*textured square only available in 7016 anthracite grey and Adjustable Jamb (Optional) The BF73 window system has been designed to be quick and easy to manufacture and install. The system offers an optional adjustable jamb feature for maximum adjustability of +/- 4mm either side during installation and is easily adjustable later with an Allen key.

Unique Lock Keep

This universal locking system is suitable for both left and right hand sides of the window, making it easier to order, stock and fabricate! It takes away the headache of having to stock both left-hand and right-hand lock keeps and alleviates the potential for error at the fabrication stage.

Robust Aluminium Cills

The main benefit of a cill is directing water away from brickwork while also offering an additional design element to the aesthetics of the window. Our aluminium cill is more robust than PVC alternatives and comes complete with plastic push-in colour matched end caps, in our standard stock colours, for a secure and sleek finish.

Cill sizes are 90mm, 150mm, 190mm and 230mm.
