PreservaTherm works by providing a thermal barrier to increase the surface temperature of wall/ceiling surfaces, which helps delay the onset of surface condensation.
Secondly, atmospheric moisture is absorbed, reducing droplet formation and releasing the trapped moisture as vapour when the relative humidity drops.
The difference in temperature between treated and non-treated surfaces can actually be felt by touch and can also help prevent warm air escaping from the property, which may lead to reduced heating costs.
