The Edinburgh range is manufactured to the highest quality and precision using the latest state of the art technology and equipment.


The unique solid, internal construction is created from a cross bonded solid core material. It is this that gives our doors a rigidity and stability unattainable by conventionally constructed UPVC doors.

The Doors are then externally covered with a vacuum formed ABS skin that looks like timber. The edges are edge-banded with PVC. The door is practically maintenance free and protected from the elements.
