A project completed near East Lothian, this project we replaced all the windows & front door, using Casement windows & UPVC Door.
This project we fitted four Casement windows using UPVC technology of double glazing & discreet draught proofing


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

Our UPVC Casements bring together classic, proven design with modern materials and technologies to create the perfect replacement windows for many different styles of homes.

Casement windows were the most popular windows across Scotland in the days before sash windows became popular. They are hinged and open in a similar manner to doors and when closed provide a high level of security.

While the old timber casement windows were susceptible to several problems such as distortion, shrinkage and rot, and required a high degree of maintenance including regular repainting, our modern UPVC Casement windows are almost maintenance free. The most they will require is an occasional clean and wipe-down.

They also provide excellent levels of thermal insulation and unlike their timber counterparts they are entirely draught free. Additionally, double glazed UPVC Casement windows offer a very high level of noise reduction, and are highly effective of reducing the sounds from busy streets and noisy neighbours.

Why choose UPVC Casement Windows?

  • There are many different kind of window designs, and some are more suitable for certain styles of building. UPVC Casement windows offer many advantages over old fashioned timber windows, yet they retain the original elements of elegance and style.
  • There are many alternative configurations and combinations. For instance you can choose top openings and/or side hung openings; you can add a range of decorative features to blend in with other features in your home.Casement UPVC Windows
