External Bifold Doors: Folding Glass Patio Doors

Transform your living space with a set of high-quality exterior bifold doors. Bifold patio doors are doors that fold in a concertina style rather than opening outwards or inwards on standard hinges. This means that they fold back on themselves to allow for optimum natural light and unobstructed views. They are also known as folding sliding patio doors, bi-folding doors, concertina doors or folding sliding doors.

External bifold doors open onto an outdoor space, rather than linking two rooms inside your home (we have a range of oak internal doors available for that too!). This means that they need to be sturdy, durable, versatile and weatherproof, not to mention stylish. And with plenty of styles and colour options to choose from, our exterior folding doors will be a stunning addition to any home (and garden!). 

Why Choose External Bifold Doors?

From experience, we know there’s no better way to enjoy your garden, patio, conservatory or orangery all year-round than by installing a gorgeous set of stylish external bi fold doors. The full-height, clear glazed panels mean that even in the depths of winter you can enjoy plenty of daylight. Watch the view of your garden change through the seasons. The folding, sliding motion allows you to open your space completely during the summer months.
