PRODUCT DESCRIPTION

The Sika® Boom-140 is a premium one-component expanding polyurethane (PU) foam designed for professional sealing, filling, insulating, and fixing applications in construction and renovation projects. With its high expansion rate and excellent adhesion to most common building materials, it provides an effective solution for filling gaps, sealing joints, and improving thermal and sound insulation.

Ready to use and easy to apply, Sika® Boom-140 cures quickly upon contact with moisture, forming a durable, lightweight foam that can be cut, sanded, trimmed, and painted after curing. It is ideal for sealing around window and door frames, pipe penetrations, air-conditioning ducts, cable openings, and wall gaps, helping reduce air leakage, dust, noise, heat, and cold transfer.
