We specialise in manufacturing traditional box sash windows. With our bespoke capacity this allows us to offer our customers a wide range of frame, sash and glazing profiles in this style. Where the conservation look is required, we can manufacture sash windows with narrow glazing bars in either the applied bar style or with slimlite double glazing.
We manufacture all our sash windows to suit the environment, period or location in which they are set. We also specialise in listed properties where existing windows and their sections have to be matched.
