UPVC Reversible Windows

Most windows are designed around what happens when you're inside looking out. uPVC reversible windows are designed around something more practical: what happens when you need to clean, ventilate, or maintain a window that you can't safely reach from the outside.

Rather than opening inward or outward like a conventional casement, the sash pivots on a central horizontal axis and rotates a full 180 degrees, bringing the outer face of the glass completely inside the room. No ladders. No scaffolding. No leaning out of the frame. Just a simple, controlled rotation that puts both sides of the glass within easy reach from indoors.

Ecologic's uPVC reversible windows are built on the VEKA system, A-rated as standard, and suited to upper-floor residential rooms, apartment blocks, commercial buildings, schools, care homes, and any environment where external window access is limited or unsafe.

What is a uPVC Reversible Window?

A uPVC reversible window is mounted on a central pivot rather than a side or top hinge. This allows the sash to rotate up to 180 degrees, so the outer surface of the glass ends up facing inward into the room, making both sides fully accessible from inside the building.

Unlike a tilt and turn window, which swings inward on a side hinge, a reversible window rotates within the plane of the opening and requires far less space behind it to operate. Safety catches built into the pivot mechanism must be released deliberately before the full rotation completes, keeping everything controlled and secure throughout.

For ventilation, the sash can be held at any intermediate angle rather than completing the full rotation, giving you precise control over airflow without fully opening the window.

Where Are uPVC Reversible Windows Used?

The reversible window was developed for environments where cleaning and maintaining upper-floor glazing from the outside simply isn't a realistic option.

Apartment blocks and multi-storey residential buildings: residents can rotate the sash inward and clean both surfaces of the glass from inside their own flat, with no specialist equipment or external access required.

Commercial and office buildings: reversible windows remove the need for abseiling operatives, cherry pickers, or window cleaning equipment on buildings where glazing would otherwise be inaccessible, simplifying facilities management and reducing ongoing costs.

Schools, hospitals, and care homes: settings where window safety, ventilation control, and low-disruption maintenance are critical requirements. Reversible windows handle all three within a single, straightforward mechanism.

Social housing and new build residential: residents can manage basic window maintenance themselves without specialist contractors, reducing the ongoing cost burden on landlords and improving long-term resident satisfaction.

Reversible Windows vs Tilt and Turn: Which Is Right for Your Building?

Both window styles address the challenge of safe cleaning and ventilation in buildings where outward-opening casements aren't ideal, but they suit different situations.

A tilt and turn window swings fully inward on a side hinge for cleaning or tilts from the top for ventilation. Because the sash comes into the room, it needs clear space behind it to operate and works best in residential rooms where that space exists.

A reversible window rotates within the frame opening, demands far less room behind it, and gives complete access to both glass faces. It's the stronger specification choice for commercial buildings, larger openings, tightly furnished rooms, and any project where cleaning access is the primary driver.
