PROBLEM TO BE SOLVED: To take in warmth through single glass when it is sunny in winter and to retain heat through double glazing after taking in warmth because the single glass is easy for the warmth of the sun to pass through and easy for a room to get warm through but easy to cool down while the double glazing is hard for the warm of the sun to pass through and hard for the room to get warm through but hard to cool down and moreover the double glazing has heat shutting-off and high heat insulating specifications but is avoided due to intercepting heat of the winter sun to make it hard to take in warmth, nevertheless heat insulating performance is better than ordinary double glazing and heat retaining property is excellent. SOLUTION: This sunny place sash comprises sliding sashes A (single glass), sashes B (double glazing) at both ends, and sliding sashes C (double glazing), and the sashes A and sashes C are opened when the sun storage sash is completely opened. When taking in warmth, the sashes A and sashes B are closed. After taking in warmth, the sashes C are closed to retain heat. Because of being doubled with the sashes A and sashes C, the sunny place sash is effective in retaining heat. COPYRIGHT: (C)2007,JPO&INPIT
