DAN-doors' thermo doors can be used as an alternative to our roller doors. The thermo door is an energy-saving solution that can be used in cold rooms and freezer rooms to ensure less heat/cold loss. DAN-doors' thermo ports contribute to a better working environment as the thorough design results in fewer issues with draughts as well as less dust and noise nuisance. The door can be installed on both the warm and the cool side of the wall.
