ProductsSash Windows - Concealed Balance


Sash Windows - Concealed Balance

The Concealed Spring Balanced Sash windows have been designed as a modern-day alternative to a weights and lines window, whilst still maintaining the traditional sliding windows aesthetic.

Our Concealed Balance windows require a smaller outer frame and can be fitted between brickwork, like a traditional casement window. This can offer cost savings over the weights and lines sash window, whilst keeping many of the same attributes.

Input Joinery's modern draught-strip technology and double glazed units reduce heat loss, draughts and condensation for an easy-care, smooth and rattle-free window operation.

A choice of mouldings, ironmongery, glass and paint finish can be chosen from our standard range to compliment your project.
