Description

An insulation reinforcement module that can reinforce the insulation performance of a door frame without insulation function without removing the door frame The present invention relates to a thermal insulation reinforcement module capable of reinforcing the thermal insulation performance of a door frame without thermal insulation without removing the door frame. More specifically, it relates to a thermal insulation reinforcement module capable of reinforcing the thermal insulation performance of a door frame without thermal insulation without removing the door frame, which allows for the installation of an insulated door by reinforcing only the thermal insulation performance of the door frame when replacing a door without thermal insulation with an insulated door. Generally, the representative steel doors are apartment entrance doors and fire doors. In the case of apartment entrance doors prior to 2008 and in the case of fire doors prior to 2018, thermal insulation performance was not required by the regulations at the time, so it was common not to install insulation on the door frames or doors. Therefore, when apartment entrance doors and fire doors made of such steel reach the end of their lifespan and are to be replaced, they must be replaced in accordance with the mandatory application of thermal insulation performance requirements under current laws. In this case, to install an insulated door or an insulated fire door that meets insulation performance requirements, the door frame supporting the door in the open wall must also be replaced. If only the door is replaced, problems arise where the door frame cools down due to external air, affecting the indoor temperature, or where moisture condenses on the surface due to condensation of airborne moisture. In other words, when replacing insulated or insulated fire doors, the door frame with thermal insulation performance must also be replaced. However, removing the existing frame and installing a new one not only incurs high costs but also presents many difficulties, such as noise, construction time, wall cracks occurring during installation, and finishing issues.
