By Victorian times, they were the most popular form of window. In the past fifty or so years, however, their popularity declined. But with the growth of a more enlightened attitude towards conservation and growing appreciation of the craftsmanship and design that went into everyday buildings of the 18th and 19th Centuries, sash windows once more enjoy a revival.
People appreciate their aesthetic and functional contribution to the house, and they are now restoring and reinstating sash windows that were removed in less enlightened days.
We will manufacture supply and install new complete box frame sliding sash windows to match the style of your original windows.
Choice of single-glazed or double-glazed. Where the double-glazed option is selected your windows are fitted with energy-saving glass as standard, giving you immediate benefit and cost savings.
Choice of Traditional Box Sliding Sash using counter weight pulleys and weights (used mainly in listed buildings where single glazing is enforced) or Spiral Sliding Sash. This is the modern version of the sliding sash window, using tensioned springs in lieu of pulleys and weights.
You also have the option to have your new windows pre-painted in a colour of your choice. Your new windows come with a high quality professional factory finish. This will save you the costly expense of employing a painter and the additional time required to complete your home improvements.
If your existing boxes are in sound condition you have the option to refurbish and upgrade all the other sections of the window.
New double-glazed sashes are manufactured in our factory to replace your original single-glazed sashes.
Low E energy saving glass, new weather sealing and locking systems will upgrade the performance of your windows to levels comparable with modern uPVC replacement windows whilst maintaining original appearance.
