Since 1955, Gaco Western has been manufacturing exceptional waterproofing and insulating products. This family owned company was built on three fundamental principles: superior products; sold by experts; at competitive prices. Today, Gaco Western coatings and spray foam insulation cover millions of square feet of commercial and residential buildings around the world, earning a reputation and trust in the construction industry as a producer of top-quality waterproof coatings, sealers, primers and insulation products.
Gaco Western WallFoam 183M is an HFC blown (zero ozone-depleting) liquid spray system that cures to a medium-density rigid polyurethane insulation material. Gaco WallFoam 183M contains polyols derived from naturally renewable oils, post-consumer recycled plastics, and pre-consumer recycled materials. Gaco WallFoam 183M does not contain CFC’s, HCFC’s or other gases harmful to the environment. This system can be sprayed on clean, dry substrates down to 35°F (2°C). Gaco WallFoam 183M is a class I fire rated foam that meets the requirements of ICC-ES AC377 Acceptance Criteria for Foam Plastic Insulation. Gaco WallFoam183M meets the requirements of AC377 Appendix X for use in attic and crawl spaces.
To ensure optimum performance, a minimum pass thickness of 3/4” (1.9 cm) is recommended with the maximum not to exceed 2” (5.1 cm) per pass. For typical equipment settings, consult Gaco Western’s GacoFoam Spray Guide.
