Smooth-sliding patio doors for reliable garden access with maximum glass area and a clean sightline.
Patio & Sliding Doors in Cosham
Cosham customers looking for patio & sliding doors turn to Aperture Windows & Doors Ltd. Sliding patio doors have evolved significantly from the narrow, sticky aluminium frames of the 1970s and 80s. Modern sliding systems in uPVC or aluminium use precisely-engineered roller mechanisms and multi-point locking to provide smooth, secure operation even on large panel sizes. The low threshold profile suits level garden access, and the low sill height maximises the view to the garden. Aperture Windows & Doors fits sliding patio doors across Hampshire and West Sussex in two-, three- and four-panel configurations, including lift-and-slide and inline-slide systems for larger openings. We specify deep drainage sills and reinforced sill caps for properties with elevated coastal or weather exposure. Cosham is a suburban district at the northern edge of Portsmouth, lying at the foot of Portsdown Hill. The area has a mix of inter-war semis and later 1960s terraces, and the Northern Quarter regeneration scheme has brought newer housing alongside the established streets. Sitting just north of Portsea Island, Cosham is close enough to the coast for salt-air to be a contributing factor in the degradation of window and door frames over time.

Patio & Sliding Doors in Cosham — FAQ
A standard sliding door slides on a bottom track under the weight of the glass. A lift-and-slide door uses a mechanism that lifts the panel slightly off the sill seal when the handle is operated, allowing it to slide on precision rollers with minimal effort regardless of the panel weight. Lift-and-slide is recommended for larger, heavier panels.
Yes — we regularly convert existing door openings to sliding patio doors, or widen the opening to accommodate a larger sliding set. The structural work required depends on whether the opening is load-bearing. We will assess this at your free survey.
