Die AGEPAN® THD Static is a structural insulating fiberboard which complies with DIN EN 13171 and the German technical approval certificate Z-9.1-725. AGEPAN® THD Static is vapour-permeable, thermal insulating and entirely hydrophobic. The asymmetrical bulk density profile makes the board extremely stable and it can be used as structural sheathing with vapour-permeable wall elements. A high level of prefabrication is possible.
