Mechanical / HVAC Plant Rooms — Condensation Control
Spray-applied natural cork thermal treatment for plant rooms, mechanical rooms and HVAC service areas. By raising the surface temperature of cold walls, steelwork and structures, an appropriate VIPEQ thermal coating helps prevent condensation in congested mechanical spaces.
Plant rooms and mechanical rooms house boilers, chillers, pumps, pipework and air-handling equipment that creates complex temperature and humidity conditions. Cold pipework, ducts and equipment surfaces, combined with cold walls and steelwork, create multiple surfaces that can fall below the dew point and condense moisture.
Condensation in plant rooms causes corrosion of steelwork and equipment, wet floors creating slip and electrical hazards, and degradation of building fabric. In HVAC plant rooms, the interaction between chilled and heated systems creates persistent condensation on cold surfaces.
Rigid insulation is often impractical in congested plant rooms — it reduces access to valves and equipment, and is difficult to form around complex pipework and steelwork. A spray-applied natural cork thermal coating applied to walls, steelwork and structures raises surface temperature and reduces condensation while preserving access.
Why Plant Rooms Are Different
Plant rooms combine cold and warm surfaces in close proximity, complex geometries, and the need to maintain access to equipment. A spray-applied natural cork coating conforms to the structure without reducing clearance — unlike rigid boards that obstruct valves, pipework and equipment.
Condensation forms when warm, moisture-laden air meets a surface whose temperature has fallen below the dew point. By improving the thermal behaviour of a cold surface, an appropriate thermal coating can help raise the internal surface temperature and reduce the conditions that lead to surface condensation.

Thermal bridge treatment at concrete columns, beams and soffits within plant rooms.
VIPEQ's cork-enhanced thermal coating systems are spray- or trowel-applied directly to the substrate, forming a thin, flexible, vapour-permeable thermal layer that conforms to irregular surfaces — steel, concrete, masonry and timber — without rigid boards, battens or significant loss of internal space.
