uPVC Sliding Glass Patio Doors: an affordable and space-saving alternative to Bi-Fold Doors

Here to help
Sliding patio doors provide an affordable way to seamlessly connect your home to your garden. They are perfect for areas where space is limited, as the sashes do not intrude into the surrounding area.
Our collection of high-quality, low-maintenance sliding patio doors offers security, elegance, and energy efficiency. They feature ultra-slim sightlines and a smooth, lightweight opening and closing mechanism.
Enhance your views and connect your garden to your home. Enjoy easy access during summer and beautiful sights in winter, allowing light and air into your home throughout the year.
The slim frames are designed to brighten up your room by maximising the glass area, allowing more light to flood in with fewer obstructions. Additionally, the easy-to-open mechanism makes it simple to enjoy fresh air. You can open the door slightly for increased ventilation or fully open it to let fresh air circulate throughout your home.
Our space-saving sliding patio doors are a great alternative to bi-fold doors for those with limited space, such as a small garden or balcony.
Ideal for conservatories, garden rooms, porches, pool houses, balconies, and internal room dividers.

Glevum Windows and doors are of excellent quality and the fitters, Matt and Dean were both quick, efficient and tidy workers. We found them both friendly and polite. We would not hesitate to recommend the Company and the service they provided.
N Harris (Pershore)
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.
J. Miller (Symonds Yat)
Excellent everyone was professional and yet friendly. I felt all were giving me good service and I felt a valued customer.
D. Morse (Lydney)
Always helpful and courteous whichever department one is speaking with.
Fitters are skilled and careful. Products are not the cheapest on the market but they are of the best quality and extremely good value for money.
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!!
