RibCore hollow core polystyrene doors are our innovative alternative to traditional honeycomb cardboard hollow core doors. In the entry market, RibCore doors offer a significant advantage with a much higher glue-to-door-skin contact area - approximately 42% compared to just 4% in honeycomb core doors.
The greater glue contact makes the door stronger with substantially greater impact resistance and delamination prevention after impact. The polystyrene core also offers enhanced thermal insulation, helping to keep your home warmer in winter and cooler in summer.

PLEASE NOTE: Stock Uni (Universal) Doors are manufactured with 4mm skins (38mm thick door) only and are available in standard widths 410mm to 910mm, in heights of 2200mm and 2400mm.
All other skin thicknesses or custom width doors are made to order and are not manufactured to be cut down. If you require a Uni door with any other skin thickness, you must specify this when placing your order.
Our 3mm 2200mm stock doors are not Uni doors and, therefore, are not designed to be cut down.
