Sealing foam is a type of material used to fill gaps and cracks in various structures, providing insulation and preventing air or water leaks. It is commonly made from polyurethane or other foam materials that expand upon application, allowing it to conform to irregular shapes and surfaces. This makes it ideal for use in construction, automotive, and home improvement projects. In addition to its sealing properties, sealing foam also offers soundproofing benefits and can improve energy efficiency by reducing heating and cooling costs. It is often used around windows, doors, and pipes, making it a versatile solution for both residential and commercial applications.
