Or it can form separately with the foamed resin board 1, and can be united using an adhesive agent, a double-sided adhesive tape, etc. (all are not shown) at the time of use.
The gap forming member 2 forms an air flow passage C through which air naturally flows even when the foamed resin board 1 is distorted when the foamed resin board 1 is placed on the air conditioner outdoor unit 5. The height shall be determined as possible.

The foamed resin board 1 is not particularly limited, but is made of polyethylene foam having a foaming rate of about 30 to 40 times, has a thickness of about 8 to 20 mm, and the light reflecting layer 11 is made of the foamed resin board 1. It is made to form in at least the one side (surface side). Thereby, it can be made lightweight and easy to produce so as to have the required complementarity, heat insulation and flexibility.
The foamed resin board 1 is not limited to polyethylene foam, but can be formed of polypropylene foam, melamine foam, polyurethane foam, or the like.
Usually, the resin material is used in the form of a plate foamed at a required foaming rate. However, when flame retardancy is required, a flame retardant can be added to the resin material, thereby making the flame retardant The foamed resin board 1 can be obtained.
The flame retardant is not particularly limited, and examples thereof include bromines such as TBBPA, DBDPO, HBCD, and TBP, chlorines such as chlorinated baraffin, phosphate esters, and halogenated phosphate esters. An inorganic system such as phosphorus, aluminum hydroxide, and antimony trioxide can be appropriately employed.

  The light reflecting layer 11 formed on at least one surface of the foamed resin board 1 is a metal foil layer formed by depositing aluminum on at least one surface of a polyethylene film, and covering the deposited aluminum surface with a polyethylene terephthalate film to form a three-layer structure. The film can be bonded to the foamed resin board 1 to form an integral structure, but this is not particularly limited, and an aluminum foil film is directly attached to at least one surface of the foamed resin board 1.
