This replaced some very old aluminium sliding doors with failing mechanism. Because this is the front entrance to the house so the right hand leaf operates as a normal door. But with a flick of four bolts they will all fold back, opening up the front of the house making the inside space connect with the outdoors. Paint work is black on the outside and oak colour on the inside this dual colours is an optional extra on all our work. Standard finish is the same inside and out.
