Description

  The present invention relates to a front door, and relates to a front door that has improved sound insulation, heat insulation, and airtightness at low cost without replacing an old front door.

  In general, as a typical renovation method for entrance doors, the first is to replace the front door with a separately manufactured front door with excellent sound insulation, and the second is airtightness on the inner periphery of the door mounting frame. As a method for attaching a frame cover for improving the quality, a method for attaching a member having sound insulation and heat insulation to an old entrance door can be mentioned.

  Of these, the first method is expensive. In the second method, in order to attach the frame cover, the opening size when the entrance door is opened becomes small, and furniture that can be carried in / out before the repair may not be able to be carried in / out after the repair. In addition, as the third method, for example, the method disclosed in Patent Document 1 can be cited, but the technique disclosed herein is a specific configuration in the members to be used as shown in FIG. The base panel 2b having a high cost ratio is used together with the cover member 35, and is not always satisfactory from the viewpoint of cost.
