Illingworth Brothers supply and install UPVC Verticular Sliding windows in Edinburgh, Lothian and throughout Scotland.

They are the perfect solution for many different styles of building especially buildings with a period character. These are one of the most popular solutions that our customers choose for installation in the more traditional Scottish buildings.

Although they are made using modern materials they have an authentic appearance that is characteristic of the traditional sash and case while offering all the benefits of modern state of the art technology.


Some of the benefits of UPVC Verticular sliders over more traditional timber frames windows are:

  • High thermal efficiency which means that you will stay warmer and cosier. The high standards of double glazing combined with advanced materials provide excellent heat retention and they are entirely draught free.
  • They require a low level of maintenance; effectively maintenance free all they require is an occasional wipe down with a cloth.
  • They will never rot, distort, or discolour and will continue to look as good as they did on the day you had them installed for many years to come.
  • Our high quality UPVC provides considerable strength and high levels of security. Our modern UPVC verticular sliders are considerably more secure than the old sash and case windows they will be replacing.
  • Easy effortless opening and closing. Old Verticular sliders have the habit of sticking which can makes opening and closing them difficult. Our UPVC Verticular Sliders will never stick or jam.
  • Excellent acoustic insulation – unlike the traditional slider, our UPVC sliders provide excellent levels of acoustic insulation. They are the ideal solution for keeping out the sounds of busy city streets and noisy neighbours.
  • We can supply them in brilliant white which will not fade or discolour. You can also choose a range of alternative colours and finishes to blend in with other features in your building.

If you are looking for replacement windows that will keep your home warm, quiet and draft free then our low maintenance UPVC Verticular sliding windows are a perfect solution for many styles of building.
