2. The utility model discloses in the big or small difference of thermal radiation that provides of a keep away hot protection curtain, the curtain body, the distribution density of splice bar also distinguishes, and it is denser to distribute in the big region of thermal radiation, can effectively restrict the deformation of being heated of the curtain body.

3. The utility model discloses in the protection curtain of keeping away heat that proposes, the existence of splice bar has increased the counter weight for the curtain body in other words, can prevent to a certain extent that the curtain body that hangs from being blown by the heat wave, influences thermal-insulated effect.
