PROBLEM TO BE SOLVED: To improve executability by lightening and further facilitating cutting at a job site. SOLUTION: With a heat insulator 4 used as a base material, a fluororesin film 7 is laminated on an aluminum foil 5 via a print layer 6. Well-known incombustible material, metaincombustible material, flame retardant material or the other woody fiber building material is applied to the insulator 4. The foil 5 has a thickness of several tens micron. The layer 6 may be executed with pattern or colors. Further, the layer 6 may be executed with mark, character or further printed with a slogan. The film 7 has a thickness of 5 to 200μm, and light transmission properties and transparency, and is applied by tetrafluoride fluororesin. And, the foil 5 and film 7 are laminated by heat fusion bonding or with adhesive via the layer 6. |
