AGEPAN® THD Putz 050 is a structural insulating fiberboard with a tongue and groove profile on all four sides, which complies with DIN EN 13171 and the German technical approval certificate Z-33.47-1724 / Z-33.47-673. AGEPAN® THD Putz 050 is vapour-permeable, thermal insulating and entirely hydrophobic. It offers exceptional surface strength and resistance when used in the external thermal insulation composite system thanks to its asymmetrical bulk density profile.
