Why Choose Aluminium Bi-Fold Windows?

Let The Light In

Bi-fold windows are superb at letting light into your home. When closed, they behave as a wall of glass which allows far more light into a room than a standard window or door. Not to mention, upon opening bi-fold doors they completely fold away, removing all barriers from between the sun and your home.
