A door is a panel or barrier, usually hinged or sliding, that is used to cover an opening in a wall or partition going into a building or space. A door can be opened to give access and closed more or less securely. The term door is also applied to the opening itself, more properly known as the doorway.

Glass and UPVC doors are mounted on a pre-built frame to match the size of the door space. Flush doors are those with a completely flat surface. They are un-paneled and have no trim around the edge.Our doors are supplied to us manufactured from an aluminum frame which is concealed by sheets of composite or aluminum. A surface veneer may also be added if the door is to retain a more natural wood-look.
Flush doors are most often used internally, when their hollow-core will be filled with corrugated cardboard. Heavier external flush doors will include a central horizontal rail to allow a letter box to be included, and the remainder of the core may be filled with hardwood blocks, particleboard or fiberboard. The frame of a fire-resistant flush door is filled with solid fire-retardant material.
