Condensation Insulation

Condensation occurs when a surface temperature is at or below the dew point; in other words, this temperature is precisely where condensation begins to increase. If the surface temperature can be maintained 1.1 °C above the dew point, condensation will not occur. The dew point is a temperature function of the moisture content/relative humidity in the air. Higher moisture content—i.e., high humidity—promotes the progression of condensation.

Our insulation materials are engineered to raise surface temperatures to at least dew point + 1.1 °C and to maintain this safety margin. The design accounts for interior temperatures, humidity, and exterior temperatures, and this performance is achieved by adjusting the applied thickness. Thus, as the (uninsulated) surface temperature drops, a greater insulation thickness is required to meet the temperature/humidity requirement.

If architects/engineers intend to completely stop thermal bridging, they must control such bridges on the relevant surfaces. Our spray-applied insulation coatings perform exceptionally on these areas. When applied—including over stiffeners (structural ribs)—the coating plays an ideal role in meeting the designer’s targets. Once installed, the net heat flow from outside to inside is greatly reduced by establishing a thermal buffer zone.
