Expanding foam for cracks and voids

Expanding polyurethane foam is a reliable construction material widely used in Nairobi and across Kenya for sealing, filling, and insulating gaps in building and renovation projects. It is ideal for door and window frames, pipe penetrations, wall joints, roofing gaps, and service openings.
The foam expands after application to fill voids effectively, creating an airtight and water-resistant seal. It provides excellent thermal insulation, sound reduction, and air sealing, while bonding strongly to concrete, masonry, brick, wood, metal, and PVC surfaces.
Commonly used by contractors and technicians in Nairobi, Kiambu, Machakos, Kajiado, and other parts of Kenya, expanding PU foam is easy to apply using a straw or foam gun and cures into a durable, cuttable material.
Key Benefits:
Effective sealing for gaps, cracks, and joints
Strong adhesion to most construction materials
Improves insulation and reduces air leakage
Fast curing and easy application
Suitable for residential and commercial construction
Expanding polyurethane foam is a practical solution for professional sealing and insulation works across Kenya.
