Bi-fold doors enables any opening to be fully opened up to ‘allow the outside in’, creating a seamless space between outdoor and indoors, perfect for those warm sunny days. With flush tracks and the slim sightlines that aluminium can offer, even when closed, these systems allow plenty of light to enter any room. Doors can be stacked when open either inside or outside and there is a choice of where you place the first door that opens which forms the immediate access through the door system. Being aluminium, colour matching with other window and doors systems is not an issue.
