Spray foam has revolutionized insulation and building. This versatile and efficient insulating solution is popular for its many benefits and ease of use. The flexible insulation material spray foam, commonly known as polyurethane foam, expands when applied. This product is made by mixing isocyanate and polyol resin on-site with specialist equipment. The chemical interaction between these components expands and solidifies the mixture, generating a seamless and effective insulation barrier.
