Upgrade your home with affordable uPVC sliding patio doors. They save space and are a practical alternative to bi-fold doors
Here to help
Bring your home and garden closer together with uPVC sliding patio doors. These doors are a practical, space-saving alternative to bi-fold doors and add security, style, and energy efficiency.
Smart as Standard: These doors come with Kubu® Smart Security Sensors. With the Kubu® Smart Alerting System, you can use a smartphone app to see whether your door is open, closed or locked, or if someone is trying to tamper with it. T&Cs apply.
Have you had to arrange your furniture just to make room for a door that swings open? A typical French door can take up about nine square feet of floor space, which means you lose space for a comfy chair or a favourite plant. This is a common problem, but modern sliding patio doors offer a smart solution. That’s why many homeowners are now comparing sliding and French patio doors to find the best fit.
Sliding doors move along a track instead of swinging into the room, so you get back valuable floor space. This means you can place your furniture closer to the glass, which is especially helpful in smaller living rooms or on compact patios.
These doors have slim frames and open smoothly, letting in plenty of natural light and fresh air all year. Their energy-efficient design can help you use less energy and save on utility bills.
Glevum’s custom uPVC sliding patio doors are well-suited for conservatories, balconies, and even as room dividers. You can choose from a range of styles and colours to match your home. They come with quality glass, good insulation, and strong security features to keep your home safe, warm, and quiet. With over 40 years of experience as a Gloucestershire-based installer and a 10-year guarantee, Glevum can help you upgrade your space. If you want to know more, you can book a free home visit.
