Introduction
Thermafleece is a sheep's wool insulation product that offers thermal and acoustic benefits while also managing moisture levels within buildings. Its hygroscopic nature allows it to absorb and release moisture, contributing to a healthier indoor environment.

Moisture in Buildings
Moisture primarily comes from occupants' activities such as breathing, washing, and drying clothes. An average family can produce 10-30 liters of moisture daily, equivalent to a full bath weekly.

Movement of Moisture
Moisture moves through air and can penetrate porous surfaces, leading to condensation when it contacts cool surfaces.

Thermafleece and Condensation Control
Wool in Thermafleece can absorb 38% of its mass in water without feeling wet, helping to stabilize internal humidity. It absorbs moisture when the atmosphere is humid and releases it when conditions are dry, reducing condensation risks.

Condensation and Temperature
Condensation can occur in both warm and cold conditions. Warm air condenses on cool surfaces in summer, while cold air picks up moisture and releases it as condensation in winter.

Thermafleece and Heat Control
Wool's ability to absorb and release moisture affects temperature regulation. It can reduce heat flow by up to 7°C in summer and increase peak temperatures by up to 4°C in winter, compared to conventional insulation.

Conclusion
Thermafleece should be used alongside other moisture management measures to optimize building performance.
