Available across our whole range of styles, we make every uPVC window to order, using the latest technology and our own unique formula. It's what makes us an industry leader and uPVC double glazing our most popular choice.

Top Quality, Tailor-Made uPVC Frames

As skilled uPVC window manufacturers with almost 50 years’ experience, we’ve developed our own uPVC formula to ensure that your windows are of the highest quality. To guarantee the best standards, we make everything ourselves in our UK factory, from extruding the uPVC granules to the final assembly and installation of the windows in your home. Our craftspeople even add your choice of finishing touches, decorative designs and opt for uPVC double or triple glazing. Every window is individually made to measure for a perfect fit, giving you the ultimate in great looks, warmth, security and easy maintenance.

  • Shoot bolt locks

    High security steel shot bolts lock into the frame at two points.

  • Excluder device

    High security anti-jemmy device resists forcing (excluding fire escape vents).

  • Key locking handles

    Key locking security handles are fitted as standard.

  • Strong construction

    Robust multi-chambered uPVC construction with welded joints for added strength.

  • Internal glazing

    By internally fitting the beading it means the glass cannot be removed from the outside. This makes your windows more secure.
