New and Replacement Wood Sash Windows

Joinery Northwest Ltd are well known for specialising in traditionally weighted sliding sash windows. We manufacture Box Sash windows in a wide variety of durable timbers ranging from European Oak, Sapele, Redwood and Accoya, and install many different types of Sliding Sash Windows, depending on your bespoke requirements.

Vertical sliding sash windows or ‘box sash windows’ were the most popular type of window during Victorian times. Their elegant proportions were also an important visual element in the Georgian period of 18th and 19th Century buildings.

However Sash windows remain as popular today as they have ever been, especially now with double glazing to improve the efficiency without affecting the aesthetics of these timeless windows.


Sliding Sash Windows

We can supply Sashes with the traditional counterbalanced system which have two equally heavy lead weights, linked via a rope and pulley mechanism, and are hidden in the sash box within the wall surrounding the window opening or a new modern sash  which is a spiral balance system which acts as a counterweight for the sliding sash. The modern mechanisms allow a slimmer frame profile.

All our hand crafted sash windows come factory sprayed which you can choose from a wide range of colours including Farrow & Ball and RAL. Alternatively, your timber products can be left unfinished to weather naturally.
