Project Details


Moisture absorption in organic thermal insulation material may level out the distribution of moisture in the material. Two mechanisms substantiate this hypothesis:
1. The insulation absorbs a considerable amount of water vapour - enough that short term condensation may not form.
2. A number of lab tests and case-studies show that water is transported through absorning materials partially driven by gradients in moisture content. As a result, absorbing insulation may be less susceptible to condensation during winter.
The experiment developed in this project will confirm or reject these assumptions in a scale and in an environment that resembles the conditions in a roof or wall construction. The setup makes it possible to control the temperature, humidity, and air pressure conditions across an experimental wall.
