Bi-Fold Doors Explained

Bi-Fold Doors, sometimes called Concertina Doors or Folding Doors create a striking visual statement and transform the relationship between the interior and exterior of your home.

They are a fantastic alternative to French or patio doors creating a 90% clear opening between your home and garden. Available in PVCu or Aluminium and with so many design options and colours available our doors can be customised to suit every home.

The outward appearance focuses on stunning glass areas, highlighted by bold frame sections styled with clean aesthetic lines. This glass maximisation leaves your home feeling incredibly light and airy.

Customer Reviews

Dec 2019 – Mr Donaldson – Bedale, North Yorkshire

Many thanks to all concerned regarding the installation process for our All Season Tiled Roof Conservatory. The roof fitters, plasterers and electricians all turned up when expected and completed their work to a high standard. They were all courteous, polite and friendly at all times and tidied up after themselves.
I would definitely consider Chatsworth for any further work and would recommend them to friends and family. Once again, many thanks!

D & J. Walker

We just wanted to thank you for an excellent job of our conservatory. From the initial advice on size and design through to the installation itself, we were delighted with the service we received from your staff.
