Abro PU Foam Spray is a type of insulation material that is commonly used in building and construction projects. It is made from a two-part liquid mixture that, when combined, expands and hardens to create a solid foam. Abro PU Foam Spray is applied using a special spray gun that mixes the two liquids together as they are sprayed out. The foam expands to fill any gaps or voids in the area where it is sprayed, providing excellent insulation properties and creating an air barrier that helps to improve energy efficiency.
