While this is a type of window design that is gaining popularity, particularly in the UK, certain considerations need to be taken into account before installation.

What Is The Application And Operation Of The Box Sash Window?

For a box sash window to operate effectively, the weight of the glazed panel is often balanced by heavy lead, iron or steel weight that is concealed within the glazing bars. The sash weight connects to the window via a braided cotton sash cord running over a pulley at the top of the glass panel frame; however, spring balances can also be used to connect the panel with the window. Breaking this cord requires damage to the chain, disassembly or trimming of the pieces.

Box sash windows need to be fitted using simplex hinges allowing the window to be locked on one side while the other side remains detached acting as a counterbalance. This is useful as it allows the window to be opened for cleaning purposes or escape.
