Sheep wool is a natural fiber that reacts spontaneously to changes in the conditions it is exposed to. This property gives it a unique position compared to other thermal insulations.

1. Cool in Summer
   When the outdoor temperature rises, the wool also warms up, which causes it to release moisture. This results in the consumption of heat for evaporation (latent heat), effectively cooling the wall. As a result, thermal flux into the building is reduced. This phenomenon can lower interior temperatures by up to 7°C in comparison to buildings insulated with alternative materials.
2. Warm in Winter
   When temperatures drop in winter, the wool cools, and increased condensation occurs within it. Its ability to absorb moisture without degrading its thermal insulation properties comes into play. Additionally, during moisture absorption, heat is released (adsorption heat). This phenomenon reduces heat flux from the building and can increase interior temperatures by up to 4°C compared to conventional insulations.
3. Naturally Breathable
   Due to its hygroscopic properties, sheep wool can absorb or release moisture without affecting its thermal insulation properties. It is therefore ideal for insulating attics and wooden building structures.
4. Health-Active
   Recent research highlights other exceptional properties of this material. It mainly includes its ability to absorb various volatile substances such as formaldehydes, cigarette smoke, and ozone, which can significantly impact the lives of allergy sufferers. Research in this area is still ongoing, and early findings suggest that its extremely high absorption capacity may have other industrial applications.
5. Energy-Efficient and Fully Ecological
   Sheep wool is industrially processed into thermal insulation with a density of 12-25 kg/m³. The thermal conductivity coefficient lambda is 0.4 W/mK, which is equivalent to standard thermal insulations. Processing sheep wool requires only 15% of the energy consumption compared to glass fiber-based thermal insulations. Sheep wool is completely safe for health. It does not irritate the skin or eyes, and its installation is very comfortable. The necessary protection against biological influences and fire resistance is achieved using natural, environmentally friendly additives.
6. Adaptable and Durable
   The fibers easily adapt to various cavities and spaces in constructions, and due to their mechanical flexibility, they reliably maintain the shape stability of the insulation, ensuring its functionality for centuries.

The U-profile serves as a seal for Canadian log houses. It ensures long-term airtight sealing of the beams in the wooden structure, thus reducing the thermal losses of the entire building. Unlike other sealing methods, the U-profile has expansion strips on the sides, which ensure a tight seal between the beams, even as the new building settles. The bottom connecting strip is made of vapor-permeable foil, and the inner space of the U-profile is filled with thermal insulation made of sheep wool. The installation of the U-profile is easy and, compared to other sealing methods, reduces the overall construction time of the house. No protective gear is needed during handling, unlike with mineral wool. The size of the U-profile is graduated according to the diameter of the beams being used.
