Tiger Foam is a brand of spray foam insulation that is used to seal gaps and cracks in buildings to improve energy efficiency. It is a two-component polyurethane foam that expands upon application to fill in spaces and create a barrier against air and moisture infiltration. Tiger Foam is known for its high R-value, which measures the insulation's ability to resist heat flow. It is commonly used in residential and commercial construction projects to reduce energy costs and improve indoor comfort.
