- calimaero SEAL The backdraft shutter is made of recycled plastic in Germany. It can be inserted into all exhaust air pipes thanks to an outer rubber ring, regardless of the ducting material. It prevents the exhaust air from flowing back or the inflow of cold outside air. The rubber flaps open and close silently. The plastic and rubber flaps are robust and weather resistant.
