Sash Window Upgrades

Bay Window with Double-Glazed Sashes

The image above shows a timber bay window that we manufactured and fitted for a customer in North Yorkshire. The bay contains six double-glazed sashes. We receive lots of enquiries regarding our sash-window, double-glazing upgrades during the colder months. You can keep the traditional look of your home and improve its thermal efficiency by upgrading your windows. Fitting energy efficient double-glazed units is a recognised means of reducing energy bills and external noise. We use Accoya® timber when manufacturing wooden windows because of its guaranteed longevity and green credentials. You can learn more about Accoya® by watching the short video on our website.

Three Sash Window Bay – North Yorkshire

Upgraded Sash Windows

We recently upgraded and double glazed the sash windows at the above property in North Yorkshire.  The new sashes were manufactured in Accoya® and coupled with 18mm Planitherm double-glazed units to improve thermal insulation.  The old sash cords and weights were replaced with a modern spiral balance system to offset the additional weight of the 18mm double-glazed units. We also fitted seals and brushes to the window frames, jambs and meeting rails in order to further reduce heat loss.

The windows were painted during the manufacturing process in our own spray-painting facility. Paint is essential to protect new wood and spray painting is cost-effective during manufacture.  It makes good economic sense to have windows manufactured, painted, sealed and finished by just one company.

The ‘Yorkshire Light’ Sash Window

The ‘Yorkshire Light’ is most probably the oldest design of sliding  sash window.  It is a simple window: one section slides horizontally and there is no mechanism to assist movement.

The horizontal-sliding sash window can be subject to water ingress and draught problems.  So, we manufacture replacement windows with a number of modifications in order to make our windows more resistant to water ingress and less draughty.  We also recommend using Accoya® when we manufacture new windows because of its proven longevity and stability.
