Metal fireproof hatches are manufactured in a similar way to metal fireproof doors. This construction is a steel frame, where a fire-resistant metal leaf is fastened to. Intracavities of the leaf and the frame are filled with fire-resistant insulant that \ expands under high temperatures, provides reliable hermetic sealing (airtightness), and prevents flame penetration into the adjoining rooms.
