Development.

InterDam’s products are branded G21 as they have all been developed in the 21st century to provide the most efficient protection possible using the most up to date engineering knowledge and manufacturing techniques. This innovation continues, with our engineers constantly making improvements to our doors, walls and windows and a commitment to constantly invest in future improvements. Example of recent innovations are certification for hanging of weight on our G21 fire panels, fully bolted installation of G21 panels and doors tested to the RWS fire curve.
