Superior Doors have raised the bar again, making their range of doors even more superior with the introduction of doors containing steel inserts. Steel insert doors are particularly suitable for use in areas where the ambient temperatures or conditions vary on each side of the door. Classic examples would be where the interior doors are used in an ensuite bathroom where there will be moist conditions on one side and dry conditions on the other side or another example could be the internal doors between the garage and the house where one face of the door is in a cooler area than the other face which is in a warmer area. Each side of the internal door sustains different environmental conditions. Features: Base material from New Zealand steel.
