If space is a concern to your customers our REHAU, DURAFLEX and VEKA Imagine profiles offer a slim-line uPVC sliding patio door, or if you prefer Aluminium, REAL Aluminium sliding doors are also available. Sliding patio doors are great at letting light in and giving great views to outside. Sliding patio doors can be installed as rear entrances or as part of a porch or conservatory for a low-maintenance and secure entranceway.
