How does spray foam prevent condensation?

A layer of closed-cell spray foam applied to the internal face of a metal surface insulates it, raising the surface temperature above the dew point. This prevents warm, moist air from condensing on the metal.

How thick does spray foam need to be for anti-condensation treatment?

Even a relatively thin application of closed-cell foam is effective as an anti-condensation treatment. The required thickness depends on the building's environment and use — contact us for guidance.

Is anti-condensation spray foam suitable for portacabins and containers?

Yes — closed-cell spray foam adheres directly to steel surfaces and is well suited to portacabins, shipping containers, and other modular metal structures.

Will spray foam stop rust on a metal roof?

By preventing condensation, spray foam removes the moisture that causes corrosion. Applied to the internal face of a metal roof, it significantly slows the onset of rust and extends the life of the structure.

Anti-condensation spray foam

Condensation on the internal surfaces of metal roofs and walls is one of the most damaging and persistent problems in agricultural buildings, industrial units, portacabins, and container conversions. When warm, moist air meets cold metal, water forms on the surface — dripping onto stored goods, machinery, livestock, and the structure itself, accelerating corrosion and creating damp, unhealthy environments.

A thin layer of closed-cell spray foam applied directly to the internal face of the metal surface raises the surface temperature above the dew point, preventing condensation from forming. The seamless, adhered application eliminates all cold bridges and leaves no gaps through which moisture can penetrate.

Spray Foam Direct Distributions supplies the PUREX NG CC2000 (formerly PUREX NG 0428NS) closed-cell system — well proven for anti-condensation treatment in agricultural, industrial, and temporary or modular structures.
