Traditional Sliding Sash

A brief history

Invented in the mid 17th century in London, the humble sash window went on to transform British architecture throughout the Georgian, Victorian and Edwardian era's.  The elegant proportions and slim sightlines form the most beautiful and efficient window style history has produced.  Despite their beauty, sash windows have always been plagued with maintenance problems such as rot, swelling or warping of the woodwork, rattling in the wind due to shrinkage in the timber, and problems brought on by careless application of paint.  The sliding mechanism of sash windows makes them more vulnerable to these problems than traditional casement windows.

Our aim was to design a sliding sash window that wouldn't rot, warp or swell, that would be weather rated to the same standard as our casement window with industry leading insulation values whilst keeping the character and charm that we've all come to love about the sash window.

As with all of our windows and doors, our sash windows are manufactured from engineered timber to combat any movement, each opener has 4 full wrap-around seals that are concealed out of sight to stop draughts and rattles.  To carry the extra weight of double glazing we use a chain system similar to the method used in some Georgian sash windows, this solves the problem of stretching and snapping of cords. We are able to offer a range of bar sizes down to 18mm to match the most slender of designs.

The acrylic based microporous paint provides maximum protection whilst letting the wood breath, this means we can offer an insurance backed guarantee covering the paint finish for 8 years. 

Our slim sash is the thinnest double glazed, traditionally weighted sash window on the market, which means it can replace that of the original perfectly without affecting the internal architrave and decoration.


As with all of our windows and doors, our sash windows are internally glazed to prevent the glass being removed from outside.  Our sash windows are fitted with 2 traditional fitch catches which are key lockable for insurance approval.  We can install a limit stop set to any height which allows ventilation in a secure position.


Our sash windows are all made bespoke, which means you can have them pretty much any size and in any configuration.  You can choose from 1000's of colours and a number of stained finishes and can have a different finish inside to outside as well as different coloured openers to the frame.  Like all of our products we offer this range in Softwood, Hardwood and Oak.
