Bi-fold doors (also known as folding or concertina doors) are made up of multiple panels that fold neatly to one or both sides, opening up an entire wall of your home. Unlike traditional patio doors or French doors, bi-folds provide a wider opening, offering unobstructed views of your garden or terrace.

When closed, they create a sleek glass façade that fills your home with natural light and warmth. When open, they transform your living space into an airy, open-plan area that seamlessly connects indoors and outdoors.

This innovative door design is ideal for modern homes, extensions, conservatories, and even traditional properties looking for a contemporary upgrade.

Benefits of Installing Bi-Fold Doors

1. Seamless Indoor-Outdoor Living

Bi-fold doors create a beautiful connection between your home and garden. In summer, open them wide to enjoy fresh air and sunlight; in winter, close them to enjoy cosy warmth while still feeling connected to the outdoors.

2. Maximise Natural Light

Even when closed, bi-fold doors act like full glass walls, flooding your home with daylight. This makes your space feel larger, brighter, and more welcoming.

3. Space-Saving Design

Unlike sliding or hinged doors, bi-fold doors fold back compactly, taking up minimal space. This makes them ideal for both small and large openings.

4. Energy Efficiency

At Harlequin Windows UK, our bi-fold doors are built with thermally broken aluminium frames and double or triple glazing. This keeps your home energy-efficient, reducing heat loss and lowering energy bills.
