Insulation blanket heat seal grommet and system for maintaining full insulation filler material thickness and methods for the same

Abstract:

A heat seal grommet for maintaining a full insulation filler material thickness about an insulation blanket through opening in an insulation blanket is provided. The heat seal grommet includes a geometric configuration formed from a cut configuration of a heat seal insulation cover film material and from a geometric form element. The heat seal grommet has a first end, a second end, and a body with a heat seal grommet through opening. The heat seal grommet further has heat sealed tabs at the first and second ends. The heat sealed tabs are heat sealed in a bent position inwardly to form a first edge at the first end and a second edge at the second end. The heat seal grommet is configured for installation in the insulation blanket, and maintains the full insulation filler material thickness about the insulation blanket through opening in the insulation blanket.
