A choice for your entrance
Where to consider MB-45 doors
- Interior structures
- MB-45 has no thermal break. It can be considered for internal doors, partitions and locations where thermal insulation is not required.
- Exterior doors for heated buildings
- For doors between a heated room and outdoors, we assess a thermally insulated MB system. Similar aluminium appearance does not make MB-45 equivalent.
