If you are planning a new conservatory, extension or just want to install some new patio doors on your home then you should certainly look into how bi-fold doors could be of use.  Unlike conventional options, bi-folding doors can fold right in or out, enabling you to open up even more space and keep the doors safely out of the way.

By creating a concertina effect, bi-fold doors can really have a dramatic impact on your space, allowing you to gain full access to a garden terrace or patio, for example.
