Casement window colour options:
Why not add a splash of colour to your windows? Our uPVC Casement windows are available in a range of foiled and colour options (standard colours and made-to-order colours).
You can even have a different colour on the inside, to that on the outside.
Alternative Configurations:
Tilt and Turn (two way opening): Tilt and Turn Windows benefit from having a hinge mechanism which allows you to tilt the window inwards (from the bottom) for ventilation or turn the window to fully open it inwards, allowing for easy cleaning. This makes them an ideal window configuration for balconies and terraced houses, due to their ability to open inwards to help you make better use of outdoor space (especially for balconies).
Bay Style Window: Designed to create a sense of space, depth, and light. Using our casement windows, they can be individually tailor-made to your exact requirements.
Bay with Tilt and Turn: You can also incorportate Tilt and Turn within a Bay style window.

A very personal service; I felt valued as a customer and they listened to what I wanted. Excellent quality of product and service. I decided not to go with a larger well-known brand as they did not provide the same personal service in the quotation stage.

Excellent service from start to finish, we had secondary Glazing fitted into our dental practice. Glevum attended when they said they would, completed the job with minimum disturbance to the daily running of the practice, and left their work place clean and tidy. The glazing has made such a difference, staff are much warmer and the radiators have been turned to low.

Glevum were prompt in quoting for the work. The order was placed and doors and windows far more quickly than other companies were able. The fitting was completed to a high standard. I'm very happy with the work and product!!
