6.3.1 Insulation of fresh air damper
Before connecting the duct section, the flange of the fresh air damper must be insulated in the
course of the fresh air duct insulation on site. This action is urgently required to prevent the for-
mation of condensation by heat transfer.
If fresh air dampers are not integrated in the AHU casing, then also the damper frame must be insu-
lated.
