PURPOSE:To prevent the deflection of a reflecting surface and the strain of a reflected image by constituting double glazing of the outside glass with a reflecting film and the inside glass, and using tempered or semi-tempered glass as the inside glass with specific thinness. CONSTITUTION:A heat reflecting film 2 is filmed to the inside of the outside plate glass 1, and a sealed space 6 is formed on the periphery between the outside plate glass 1 and inside plate glass 3 through a spacer 4. At that time, various kinds of glass can be used for both plate glass 1 and 3, and at least tied or semi-tempered glass can be used for the inside plate glass 3. The thickness of the inside plate glass 3 has the thickness less than 70% of that of the outside plate glass 1. Such double glazing as bending against rigidity of the outside plate glass 1 is easily made and as deflection corresponding to expansion and contraction of air in the sealed space 6 is easily made is adopted. |
