Lowest cost solution for fire and blast walls

InterDam’s innovative G21 Fire Panel and Blast Panel provide the ultimate in weight-saving, ease-of-installation and cost saving for both onshore and offshore applications.. Available for A0, A60, H60, H120, J30 and J60 fire ratings and blast loadings up to ~1.0 bar, our lightweight sandwich panels are quick to install and allow for penetrations to be placed after the panels have already been installed. As well as speeding up construction during new-build, the G21 panels are ideally suited for retrofitting applications as they can be installed as a bolted solution, removing the need for hot-work in an existing facility.
G21 panels are certified for internal and external walls, for onshore and offshore application and for fire and blast protection.
