Why choose bi-folding doors?
Flood your home with natural light with our custom-built bi-folding doors.
Stretching from floor to ceiling, bi-folding doors create a sense of space in your home – and, if you have them opening out onto the patio, bring your home and garden closer together.
But these elegant, contemporary doors aren't just a showpiece – they're built for practicality as well as style. As with all our products, they're easy to operate, easy to maintain, super-sturdy, super-secure, energy-efficient and weather resistant.
Realise your home's potential for space, light and beauty with this classic look.
Super secure
You want security as well as luxury. Our bi-folding doors are fitted with a high-security Yale locking system – and each product has been tested for safety.
Range of colours
Match your bi-folding doors to your interior design with our range of stunning colours.
High quality
Our bi-folding doors are affordable – but we don't cut any corners where quality's concerned.
Weather resistant
As well as being sturdy, our bi-folding doors are built for British weather. They're long-living and easy to clean.

Choose from a huge range of colours and designs.
Our bi-folding doors can span the full length of a room. But when they're open, they take up very little space thanks to their concertina design.
Enjoy an uncluttered wall-length view of your garden – or create a sense of space with a see-through divider between rooms.
Like all our range, our bi-folding doors are up-to-date. That means they keep the heat in and keep burglars out.
The doors glide effortlessly along their track and maximise the natural light in your home. Easy to operate, easy to clean – and available in a range of appealing colours.
