Here to help
Enhance your home’s connection to the garden with uPVC Sliding Glass Patio Doors. This cost-effective, space-saving alternative to bi-fold doors offers security, elegance, and energy efficiency.
Smart as Standard: These doors include Kubu® Smart Security Sensors. The Kubu® Smart Alerting System lets you check whether your window is open, closed, or being tampered with via a smartphone app. T&Cs apply.
Is your furniture arranged to accommodate a door that swings wide open? A standard hinged French door, for example, can demand about nine square feet of clear floor space just to function—an area you can’t use for a cosy armchair or a favourite plant. This common frustration is where modern, space-saving sliding patio door solutions completely change the game, making the sliding vs French patio doors debate a critical one for many homes.
A sliding door moves along a track rather than swinging into the room, reclaiming valuable floor space. This allows you to position furniture closer to the glass, optimising layouts in smaller living rooms or compact patios.
With slim sightlines and smooth operation, these doors provide natural light and ventilation year-round. Their energy-efficient design helps reduce your carbon footprint and lower utility costs.
Glevum’s made-to-measure uPVC sliding patio doors are versatile and suitable for conservatories, balconies, or internal room dividers. A variety of configurations and colours are available to suit your preferences. High-quality glass, insulation, and security features enhance safety, warmth, and noise reduction. With over 40 years of experience as a Gloucestershire-based installer and a 10-year guarantee, Glevum is well-positioned to support your upgrade. To learn more, request a free home visit.
