A composite joint sealing gasket (8) includes an elongated flexible, resilient member (10) typically of an elastomer or polymer, for example, elastomer rubber, thermoplastic elastomer or thermoplastic polymer with memory, for example, EPDM or neoprene, and has opposed elongated upper and lower longitudinal edge portions (18, 16); the upper portion (18) defines a sealing element (40, 42); a tacky sealing composition (12), for example, a mastic composition is supported on an outer surface of the lower portion (16) remote from the sealing element (40, 42). The gasket (8) may be employed in a variety of environments where a seal is required, for example, between wall and ceiling panels, or as a glazing gasket to provide a seal with a window; when employed as a gasket the sealing element provides an outer seal with a window and the mastic composition provides an inner seal between the window and sash; streaking of the mastic composition across the window pane is avoided and the resilient member facilitates installation and provides an aesthetically pleasing appearance.
