Experience our

Heritage windows

Heritage windows include the traditional detailing found in period timber box sash windows. With this in mind, we have included a deep bottom rail, Georgian bars, run through sash horns and foil laminate options to mimic the look of painted wood.

Steel-reinforced sliding latches allow the sashes to be tilted inwards to enable the window to be cleaned from the inside of the property, yet the facility is concealed for aesthetic and safety reasons.

The latches can be locked off to prevent unauthorised tilting of the sash.
Standard balances of 14mm or 19mm diameter may be used, and it is also possible to fix all hardware into a specially designed steel or aluminium section for increased security performance.
