Bönen needs penetration seals that hold the fire-compartment boundary, pass the inspection, get signed off.
Every wall penetration in Bönen that crosses a fire-compartment boundary needs documentation: approval number. Consultants check this every year. Insurers reference it at renewal. A missing seal is the kind of finding that delays sign-off.
