Add a splash of colour.
Our Sliding Sash Windows are available in a variety of colour finishes, including classic white, woodgrain options such as rosewood and golden oak, and several modern solid colours. While white provides a clean, timeless look, you may prefer another finish that better suits your property. You can also select different colours for the interior and exterior frames, such as a woodgrain or coloured finish outside and white inside. The choice is yours.
Coloured window frames offer the appearance of traditional painted timber while providing the benefits of modern uPVC, such as improved security and energy efficiency. Glevum’s coloured uPVC windows retain their appearance year after year with minimal maintenance. The fine wood grain effect preserves the authentic look and feel of timber frames at a lower cost.

R. Savage (Worcester)
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.
H. Pugh (Gloucester)
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!!
