Why Choose Casement Windows
Casement windows are strong, reliable and one of the most popular choices throughout the UK. Choose from either side or top opening windows that are easy to maintain, easy to clean and long-lasting.
Combine your new casement windows with our 28mm double glazed or 36mm triple glazed glass to stop heat escaping your home and keep energy bills as low as possible!
All homes built in the UK suit casement windows, so there’s no worry of the windows looking out of place on your property. This versatility is the reason they are the most popular style of window in the country. With an elegant curved shape that can help enhance any home and the flexibility you’d expect. The Spectus Ovolo system is suitable for almost any size or layout of casement windows.
All our UPVC windows are competitively priced and come with the assurance of the BSI Kitemark quality guarantee. Call our team today on 01724 859326 to find out more.
Our casement windows have an A++ energy rating and a 1.2W/m²K U-value with double glazing.
Our UPVC Casement Windows Are...
Low Maintenance
Casement UPVC windows will never lake, peel, rust or rot and are relatively maintenance free to keep the ongoing work low going forward.
Designed To Retain Heat
Our standard windows are 28mm thick, double-glazed units for low-e energy rating and thermal efficiency. We also supply a 36mm triple-glazed option.
Built To Last
Glazing beads are fitted internally for extra security and opening frames are fully weather stripped.
Impressive Aesthetics
Our windows have equal frame and bead sight-lines. This coupled with a fully integrated system works perfectly to provide an immaculate finish.
Powerful Performance
A large reinforced 5-chamber system increases thermal performance. Choose from 5 glazing sizes including 24mm, 28mm, 36mm, 40mm and 44m.
Intelligent Design
Drainage paths are carefully positioned for efficient routing and knock-in beads enable speedy installation and easier glazing.

Our casement windows are available in a range of colours, with the option to have different colours inside and out. This allows you to keep your windows completely in line with the look and feel of your home.
Choose from 3 different woodgrain shades; Mahogany, Golden Oak or Cherrywood.
