Using glazing rebates of 40 x 20mm, our Advanced casement window is factory fitted as standard with 22mm (4/14/4) ‘Low E’ double glazed sealed units. The glazing system has timber beads all round as standard, but an alloy bottom bead can be fitted, if required, for improved performance.

The timber beads are fixed using Allan Brothers’ fixing system to enhance product integrity and appearance.

Specialist glazing, e.g., argon filled, bronze anti-sun or laminated, can be fitted, if required, to give additional insulation and/or security.
