Bespoke Timber Sash Windows

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. Come and view our selection of Sash Windows at the Liverpool offices.


Venetian SashVenetian sash 300

Our Venetian Sash Window is a triple sliding box sash window, where the outer two panes are fixed and the centre sash slides open, and feature slender mullions. This style of window was the standard design 100 years ago for terraced houses all over the country. The weights that balance the central sash are located in the outer two boxes, thus allowing a smooth movement and the central mullions between the sections to retain their narrow aesthetic.


Traditional Sliding SashSash-corded-out_300

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.


Sash for listed properties Slim-sash 300

Our Conservation Box Sash window features many bespoke options, allowing them to be closely tailored to the individual requirements of a historic or period building. A wide choice of profiles are available including Georgian, Gothic, Victorian, Queen Anne and Lambs Tongue designs to faithfully replicate a host of period styles. Double glazing in a range of thicknesses is available as well as single glazed options to satisfy planning requirements for certain listed buildings. Heritage style glasses may also be specified to give an authentic, uneven finish to the panes.


Hidden spring sashSpring sash 300

We maintain the traditional sash window appearance with our Hidden Spring Sash Windows – reproducing the original charm and character of English sash windows in their form but incorporating double glazed units and using spring balances rather than counterbalance weights. To ensure that the double glazed sash windows remain true to their traditional style the springs are concealed neatly within the frame. This innovative Hidden Spring Sash Window is specifically useful in modern buildings without sufficient rebate to accommodate a full box sash.
