SashLine manufacture and install the finest quality sliding sash windows, produced and finished to the highest of standards in our own factory – an affordable luxurious addition to any property. Supplied and fitted by our FENSA regulated team in single units for homeowners or in bulk orders for our builder, contractor and developer clients.
We produce traditional box and spiral sash windows to any dimensions in Victorian, Edwardian, Georgian and contemporary styles – to perfectly match the look and feel of your existing windows (including in conservation areas and on listed buildings), or to add a touch of class to your new development.

All of our windows are produced to the UK’s CE standards and all of our double-glazed units meet modern thermal insulation standards, so no annoying draughts.

SashLine’s sash windows come in a choice of 5 woods, all from sustainable forests, finished in either a rich wood stain or a four-coat, weather-resistant, factory applied paint, both inside and out, with a choice from a kaleidoscope of colours.

Because we manufacture and finish all our sash windows ourselves we are in complete control of the supply chain so you can be assured that the delivery date we state is the delivery date we deliver on, every time.
