| abstract |
The invention comprises a method of insulating a structure. The method comprises providing a quantity of a foam-forming composition between structural elements and permitting the foam-forming composition to expand to form a foam. The foam-forming composition comprises an aqueous emulsion or solution of a natural or synthetic film-forming polymer, a surfactant, hydrogen peroxide and an activating agent which causes the hydrogen peroxide to release oxygen gas sufficient to produce a foam. An insulated structure is also disclosed. |
