Bi-fold doors are a favourite for homeowners who want to maximise space and optimise natural light. Panels of glass joined together rest in top and bottom rails. When opened, glass bi-fold doors slide along the rails and stack together, creating a wide opening. When closed, panels form a wall of glass that protects against rain and heat. Wooden bi-fold doors work well as interior doors, creating an attractive room divider when closed and opening up more space when needed. We custom-make thermally broken aluminium bi-fold doors with double-glazed and triple-glazed options. Contact us about our bi-fold door prices.
