Dear all,
Does someone have experience using sheep wool as insulation in a humid-moderate climate?
Temperatures here are ranging from 15-25 degrees and an humidity range from 70-85%.
Humidity and mould is an overall problem in this area and we would like to take this in account when designing our house.
We keep in account these key factors: cross- ventilation, sun orientation, overhanging roof, vapor open building, elevated wooden structure
We like to use sheepwool insulation because they can say it regulates humidity and has a natural synergy with wood. It is able to absorb a large percentage of its weight in moisture, without compromising its insulating ability
and adsorbs the moisture when humidity is lower ( only found 1 website saying it adsorbs at 65% RHL). The sheep wool fibres draw out the moisture, conditioning the wood and act as a ‘buffer’ to protect the fabric of the building.
But what if the climate is always above 65%? Is it enough when the indoor climate in winter is warmer and therefore it is possible to have more moisture in the air and in addition to ventilate?
Hope someone can help me!
