PROBLEM TO BE SOLVED: To solve a problem in which in a curtain or shade installed at a window, lighting adjustment and blindfolding as an original function and a design function have priority while an inflow loss rate of heat from the window is very high, and a heat shielding material constructed inside a building structure has a very high reflection effect rate of heat but cannot be adopted to the window due to processing difficulty, a several-millimeter thickness allowing no light transmission, and a metal color.SOLUTION: On a generally whole face on a rear face side (outdoor side) of a plain shade G formed of a curtain fabric, a sheet-like heat shielding material A is attached and fixed which has a horizontal creasing processing at predetermined intervals for enabling folding required for opening/closing, and has a high reflection effect. The heat shielding material A is easily processed and attached as a back fabric of the plain shade attached at the window, and thereby the heat of inflow loss is suppressed at an appropriate time and the lighting adjustment and blindfolding is enabled at an appropriate time.SELECTED DRAWING: Figure 1 |
