A removable cartridge barrel (20) of a hot glue dispenser (10) is removably secured to a feeder handle (16) by a releasable latch (24). The cartridge barrel (20) includes a protective housing (26) which includes an interior cavity (160) within which a heating cartridge (22) is mounted, with an air gap (170) extending substantially fully between the heating cartridge (22) and the protective housing (26) to provide a thermal barrier. Air ports (169) extend through a forward end of the cartridge barrel (20) to vent the air gap (170) exteriorly of the cartridge barrel (20). A feed passage (150) extends interiorly through the heating cartridge (22) for passing a glue stick (15) from the feeder handle (16) to a dispensing end of the heating cartridge (22). A nozzle (145) is provided on the discharge end of the heating cartridge (22) to provide a dispensing tip (147) for dispensing a melted end of the glue stick (15). A thermally protective shroud (172) is mounted to the exterior of the nozzle (145).
