INSULATED CORRUGATED FIBER CEMENT SHEET, AND METHOD FOR PRODUCING SAME

摘要

A method of producing an insulated corrugated fiber cement sheet (1) is described. The method comprises providing a cured corrugated fiber cement sheet, shrinking the cured corrugated fiber cement sheet, shrinking the cured corrugated fiber cement sheet and adhering a thermal insulation panel (2) having recesses (3) such that these engage with the undulations (4) of the fiber cement sheet (7) while leaving openings (5) for acclimatization. Disclosed is also an insulated corrugated fiber cement sheet (1), a thermal insulation panel (2) for producing such an insulated corrugated fiber cement sheet, and a kit of parts comprising the fiber cement sheet (7) and the thermal insulation panel (2).

1: Method of producing an insulated corrugated fiber cement sheet (1), comprising the steps of:
a) providing a cured corrugated fiber cement sheet; b) shrinking of the cured corrugated fiber cement sheet, thereby providing a pre-shrunk corrugated fiber cement sheet (7) having a residual shrinkage in the direction of the corrugation is less than 4 mm/m; c) adhering a thermal insulation panel (2) comprising a plurality ref elongated recesses (3) to one side of the pre-shrunk corrugated fiber cement sheet (7) having undulations thereby providing said insulated corrugated fiber cement sheet (1), the recesses having a shape for partly engaging with the undulations (4) of the pre-shrunk corrugated fiber cement sheet (7) while leaving openings (5) between the thermal insulation panel (2) and the pre-shrunk corrugated fiber cement sheet (7) for allowing air flow on both sides of the fiber cement sheet.
