Sash window box/frame depths

Equally important as the width or height of the new sash window is the depth of the sash box, often overlooked by many companies the sash box needs to match the depth of the recess, so that it fits inside the sash reveal and is flush with the inside wall. If overlooked you could end up with your new windows protruding into the room. The depth of a sash reveal is usually between 140mm and 150mm in period properties.

Using a deeper frame means architrave will have to be packed out which can look very bulky and not in-keeping with your property.

At Kensington Sash Group Ltd, our highly skilled surveyors will ensure that your new timber products fit perfectly into the aperture in every given aspect.
