PURPOSE:To appropriately adjust the amt. of heat due to sunlight transmitted by forming many film-coated faces on one of the inner faces of a transparent laminated plate glass with a heat ray-reflective compd. and adjusting the heat ray reflectance or transmittance of the compd. and the area ratio of the film- coated face to uncoated face. CONSTITUTION:Many film-coated faces 2 are formed on one of the inner faces of two transparent plated glasses 1a facing each other in parallel with a heat ray-reflective transparent compd., hence the heat ray of sunlight is transmitted through the glasses 1a into a room or reflected, and the cooling load against an increase in heat in the room and the heating load against the liberation of heat in the room are reduced. The heat transmitted through one plate glass 1 is set by adjusting the heat ray reflectance or transmittance of the compd. and the area ratio of the film-coated face 2 to uncoated face 3. |
