    Abstract: A method for insulating a polymeric fabric of a shelter which comprises: applying a fabric material (e.g., a natural fabric) to at least a portion of the polymer fabric; and applying an insulation material to the natural fabric opposite to the polymer fabric or treating the polymeric fabric to allow for direct application of the insulation material. The surface treatment is either roughing, electrostatic surface treatment, chemical surface treatment, primers, adhesives, solvents, or other coatings to enhance adhesion to the insulation material.
