A thin glass fiber layer made of glass short fibers having a diameter of 1 to 4 μ, a glass short fiber having a diameter of 1 to 4 μ, and a sound absorbing heat insulating plate made of glass short fibers used in contact with flowing air. It consists of an intermediate layer containing short glass fibers with a diameter of 5 to 11μ and a thick glass fiber layer consisting of short glass fibers with a diameter of 5 to 11μ, and contains 3 to 15 wt% of short glass fibers as a solid component of uncured binder. An uncured composite glass fiber mat of ~ 4Kg / m 2 with a thickness of 8-100mm and a density of 3
0-80 Kg / m 3 , and press-heat to produce a glass short fiber board so that the thin glass fiber layer has a surface to be used in contact with flowing air. Ethylene vinyl acetate emulsion, vinyl chloride emulsion, acrylic emulsion or rubber latex is applied to the surface of the fiber layer and dried, and a coating layer made of ethylene vinyl acetate resin, vinyl chloride resin, acrylic resin or rubber is applied to the surface. A sound-insulating heat insulating plate.
