A tubular, thermally insulating gasket product is produced using as a mounting element a bulky knitted tape of glass fibre, ceramic or other heat resistant material. The tape has a main body portion knitted using a rib or interlocking stitch for firmness and body and a lip portion adjacent to the body portion knitted with a plain jersey stitch. The lip portion has an inherent tendency to curl back upon itself so as to hold the body portion on a flanged door frame or the like, freeing the installer's hands for installation of a clamping front frame or other fasteners. A tubular gasket of known construction is fastened to the main body of the tape along a single sew line. For increased flexibility, one or more ladder portions may be formed running lengthwise of the ribbon within the main body portion.
