Super strong and thermally efficient, Flat Roof Home Extensions
Here to help
Contemporary and Traditional Flat Roof Home Extensions, fully compliant with the latest Building Regulations, thermally efficient and can be complimented by either Ultrasky Flat Skylights or Ultrasky Lanterns.
Contemporary Flat Roof Extension
If you’re a fan of clean modern lines, then a Flat Roof extension with Ultrasky Skylights will be the perfect choice for you. The frameless flat skylights will flood your room with natural light for an extension that is as cosy as it is beautiful.
Traditional Flat Roof Extension
If traditional grandeur is more your style, then Ultrasky Lanterns will make a stunning statement.
Combine the Ultraframe Flat Roof system with Ultrasky Lanterns for an elegant orangery in a fraction of the time of a traditional orangery build. Perfectly pitched at the optimum angle of 25°, Ultrasky Lanterns will allow the maximum amount of natural light to flood into your orangery, for a room that is light, bright, and airy.
Super-Strong
The Ultraframe Flat Roof system is strong enough to span up to 5.6m unsupported above bi-fold or sliding doors without expensive and often cumbersome additional support, bringing style and simplicity to your Flat Roof extension design.
For your peace of mind, all the structural and thermal calculations are taken care of within our specialist design software which engineers the roof for your exact postcode to make sure your new Flat Roof extension is prepared for the worst possible wind and snow loads in your location.
Thermally Efficient
The strength of the Ultrasky Lantern means that, not only do the Ultraframe lanterns look beautiful, but the strength of the ridge also means that there are 25% fewer bars. This technology ensures there are no cold spots and makes Ultrasky Lanterns the ideal choice for kitchens where high condensation levels need to be carefully managed.

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)

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!!
