Typically, sliding sash windows comprise two sliding sashes that move up and down within their frame, supported either by weights or by modern spring balances. They have evolved over the centuries and the windows we are replacing today are very elaborate, in-keeping with Victorian tastes, with deep bottom rails, decorative horns and contoured glazing bars.

Cleaning the outside of your windows
KAT’s Box Sash Windows feature an easy clean system that allows the outside of your window sashes to be cleaned from the inside of your home, thanks to the tilt facility.
Bespoke window furniture in a choice of finishes
KAT has designed bespoke window furniture, including cam catches to lock the windows, sash lifts to hold onto whilst sliding the bottom sash upwards, ring pulls to slide the top sash downwards and an opening restrictor so that the window cannot be opened beyond a certain point.
