PROBLEM TO BE SOLVED: To provide a composite sheet for a building component composed of a core material of synthetic resin foam of which one face is provided with a front face material and another face is provided with a rear face material, which is suitable for the rear face material allowing the front face and the rear face to have a pattern and a shape freely selected, preventing defects such as warpage of the building component, and keeping the rear face material free from wrinkles in a manufacturing process, with thin thickness; and a building component having the composite sheet at least on one face of the synthetic resin foam.SOLUTION: A composite sheet for a building component as the rear face material is composed of a nonwoven cloth including glass fiber, to which at least two kinds of synthetic resin films having different breaking strength are laminated. The rear face material has a compression strength of 0.30 to 1.00 kN/m in the lateral direction, and a weight of 50 to 120 g/m. |
