Spray foam is a high-performance insulation material applied as a liquid that quickly expands into a dense foam. It fills gaps, cracks, and cavities, creating an airtight and moisture-resistant seal. Spray foam provides excellent thermal insulation, reduces heat transfer, blocks air leaks, and helps control condensation. It is ideal for container insulation, buildings, walls, roofs, and ceilings, improving energy efficiency, comfort, and durability while also adding structural strength and sound insulation.
