A gasket structure permitting the selective variance of components thereof whereby high torque retention, heat insulating and fluid-tight sealing is obtained. The specific disclosure and application of use is in a gasket-heat-insulating assemblage for providing insulating and sealing functions between, for instance, the throttle body and bowl or the throttle body and the manifold of an internal combustion engine carburetor assembly. By increasing the density of the heat insulating member at the bolt hole portions by which the member is retained in the assemblage, as by means of densification or the provision of a suitable insert member, torque retention and the spring effect of the member may be controlled. Additionally, by providing gasket layer components on one or both sides of the insulating member, especially where one is furnished with a sealing band, fluid-tight sealability in the intended field of use is maximized. Methods for forming specific specific constructions are also disclosed.
