How Do I Insulate Steel Without Insulation Boards?

Insulating steel with rigid boards is difficult. Steelwork, cladding and metal roofs have complex profiles, and boards require battening, mechanical fixings and cutting around details — all of which introduce thermal bridges, cavities and access issues. In plant rooms and congested steel structures, boards are often simply impractical.

A spray-applied natural cork thermal coating adheres directly to the steel surface, forming a continuous thermal layer that follows the profile of the steel — no battens, no boards, no fixings and no cavities. This makes it particularly suitable for steel substrates where rigid insulation is impractical.

By improving the thermal behaviour of the cold steel surface, an appropriate VIPEQ cork-enhanced thermal coating can help raise its surface temperature and reduce the conditions that lead to condensation — directly on the steel, without the complexity of board systems.
