Modular Buildings — Thermal & Condensation
Modular Building Insulation & Condensation Control Ireland
Spray-applied natural cork thermal barrier for modular homes, prefab buildings and offsite-construction units. By raising surface temperature and treating thermal bridges, an appropriate VIPEQ thermal coating helps control condensation in modular structures.
Condensation & Thermal Bridging in Modular Buildings
Modular and prefab buildings are constructed with lightweight panels and junctions that create multiple thermal bridges. Where panels connect, at floor-to-wall and wall-to-roof junctions, and around openings, the insulation layer is interrupted — creating localised cold spots that condense moisture.
Timber modular buildings are particularly vulnerable: low thermal mass means surfaces cool rapidly, and trapped moisture from condensation can threaten the timber structure. Traditional rigid insulation is difficult to retrofit in factory-built units and adds thickness that affects transport and assembly tolerances.
A spray-applied natural cork thermal coating applied to modular walls and junctions raises surface temperature and treats thermal bridges directly, conforming to the panel geometry without adding significant thickness — and remaining vapour-permeable to protect the timber structure.
Why Modular Buildings Need a Different Approach
Modular units are built to tight dimensional tolerances for transport and assembly. A thin-film spray-applied natural cork thermal coating treats thermal bridges without adding the thickness that rigid boards introduce — critical for maintaining factory-built panel dimensions.
Surface Temperature, Dew Point & Condensation
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.

Key Benefits
Where Thermal Treatment Applies
Modular Homes
Condensation control and thermal bridge treatment for residential modular and prefab homes.
Timber Modular Units
Vapour-permeable thermal coating for timber-frame modular units where moisture must not be trapped.
Panel Junctions
Thermal bridge treatment at wall-to-wall, wall-to-floor and wall-to-roof panel connections.
Offsite Construction
Factory-applied thermal coating as part of the offsite manufacturing process.
Modular Classrooms & Offices
Condensation control for modular school and office units with lightweight construction.
Window & Door Reveals
Thermal treatment around openings where thermal bridges cause localised condensation.
A Natural Cork Thermal Coating — Not a Paint
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.
