Manufactured using cutting edge technology, our doors are made of glass reinforced plastic (GRP) with an inner core of high density foam and are available in a huge range of styles which complement a home perfectly. Composite doors from Crystal Direct will give a home excellent heat retention due to its insulated foam core and weather resistant seals. The PVC-U outerframe will also provide additional insulation. Installed with a multi-point locking system and high security hinges our doors will keep homes safe and secure. Composite doors are incredibly easy to care for and they won't discolour, fade or warp. Simply wipe down with warm soapy water with a soft cloth to remove any grime or dirt.
