Our PU spray foam provides superior thermal insulation, soundproofing, and moisture control for residential, commercial, and industrial applications. Whether you are insulating cold rooms, buildings, roofs, tanks, or industrial pipelines, Kingsman’s PU foam spray guarantees long-lasting protection, reduced energy costs, and excellent structural stability — perfectly suited for Kenya’s diverse climatic conditions.
What is (PU) Foam Spray?
Polyurethane (PU) foam spray is a two-component insulation material made by combining:
-
Component A: Polyol blend
-
Component B: Isocyanate
When mixed and sprayed, the two react to form a rigid, closed-cell foam that expands up to 30 times its liquid volume — filling cracks, cavities, and surfaces to create a seamless, airtight, and waterproof insulation layer.
This makes (P U )foam spray one of the most efficient modern insulation materials in the world.
