Equipment to investigate moisture distribution in absorbing insulation materials

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.
