The Inna-Dor 60 is a high quality steel doorset for use internally to prevent the spread of fire but also to be a door in its own right with multiple options on the specification, finish and colour depending on the environment. It is available as a single or double leaf doorset and is made to measure for a perfect fit every time further enhanced by the use of an adjustable outer section on the very robust steel sub frame which is always factory fitted before delivery.

The Inna-Dor is tested to BS 476-20, BS 476-22 and BS EN 1634.

The Inna-Dor can be specificed with so many variations in windows, handles, locking and other aspects but underneath it all it is a tested and fire rated door with a 60 minute certificate. The door can also offer very good levels of insulation with its mineral wool core.


Internal FD60 fire rated steel doorset  for use in multiple applications - commercial, industrial or domestic. The only variation to make it applicable to an enviroment is the change of colour, finish and furniture used, albeit it has to be within the parameters of the fire testing.
