Windows: Sash & Casement

image 1Sash windows have been the popular choice of window from the Georgian period right through to the late 1920's. Georgian sashes were more typically two moveable sashes divided each into six panes with narrow glazing bars. The Victorian sash became more decorative with multi panes with leaded lights. In 1894 the Building Act changed the regulations, so that windows no longer had to be flush with the exterior wall. This enabled windows to stand proud from the facade. The Edwardian period took advantage of the change in building regulations and now presented their windows in bays. Medium and larger houses would often display double bay or bow windows. Edwardian sash windows would often fix the upper multi pane but use a single pane of glass below to maximum the light into the room. Sash windows would often be painted in the Queen Anne style of white.

 

"The sash offered many advantages, including being better suited to the wet British climate, as it can be closed down to a narrow gap, allowing for good ventilation whilst reducing the chance of rain entering. Being contained within the box, the sashes are less susceptible to distortion and rot than a hinged casement adding greatly to their life span." Sash Window Specialist

English Heritage has released the findings of a study into the thermal performance of traditional sash windows using a 2 x 2 timber sliding sash window dating from the 1880s which had been rescued from a skip. The results showed that even the simplest repair and basic improvements will bring significant reduction of draughts and heat loss, and that using a combination of these methods will upgrade a window to meet Building Regulations targets.

Casement Windows

Casement windows are hinged windows set in a fixed frame. They were often found alongside sash windows in Edwardian houses. In the 1930's there popularity increased and took over from the sash window. Casement windows were either painted wholly white or the frame was painted in a dark colour with the inner edge highlighted in white.

   
     

 

 

Oriel Windows

A oriel window projects from the upper story of a building, supported on brackets or corbels. The Oriel window became popular feature in the late Victorian Arts & Craft houses and soon became a regular addition to many Edwardian homes.

"They are a good means of improving a view that is not too special but where the street has a pleasant view at the far end. Good examples are in seaside towns, where terraced houses may be crammed in a street but the view of the sea at the end is well worth seeing." Homebuilding & Renovating
