Composite performance fire door with improved heat insulation

摘要

The present invention relates to a multifunctional fireproof door, comprising: a front surface panel constituting a front surface of the fireproof door; two side surface frames each disposed in a rear area at both sides of the front surface panel and constituting both side surfaces of the fireproof door; a rear surface panel disposed in the rear area of the front surface panel to connect rear end portions of the side surface frames to each other and constituting a rear surface of the fireproof door; and a partition panel disposed between the front surface panel and the rear surface panel and dividing a space between the front surface panel and the rear surface panel into a front portion and a rear portion. Therefore, the space between the front surface panel and the rear surface panel is divided into the front portion and the rear portion by the partition panel, and thus heat insulation can be increased.
