Expanding foam is a versatile solution for general-purpose gap filling in construction projects. Activated by moisture, this self-expanding polyurethane foam adheres well to all common building materials and remains resistant to water, heat, and aging. Its excellent sound and heat insulation properties make it suitable for both internal and external use, contributing to energy efficiency and comfort. Once fully cured, it can be cut, sanded, plastered, and painted to match surrounding surfaces seamlessly. With a high gap-filling yield, it effectively fills and insulates holes, voids, gaps, and joints in various construction applications. It's particularly useful around window and door frames, as well as for insulating around pipes and electrical wiring, providing a reliable solution for achieving air and thermal barriers while offering ease of application and versatility.
