Benefits of using sheep wool insulation.
Our insulation products are used to reduce heat loss and sound transfer in a variety of applications. Eco Friend Sheep wool insulation meets the requirements and standards applied to residential, commercial and industrial environments.
Wool as an insulator
Wool’s natural structure makes it incredibly effective as an insulator. Each wool fiber is composed of protein molecules (keratin) organized into five follicles. These fibers effectively trap air, moisture and harmful chemicals. Using wool as insulation actually helps keep your home warm in the winter and cool in the summer, while improving indoor air quality.
Fire behaviour
Due to the consistent use of 100% virgin sheep's wool, the special EFS wool processing technology and the innovative, our sheep's wool insulation achieves fire classification B according to TS EN 13501-1 - Surface exposed to flame
The natural fibre of sheep’s wool has a self-ignition temperature of 600° C. This is about twice as high as wood (270° C). It shrivels away from any heat source without the material melting.
Best insulation values
Thermal conductivity is one of the most important insulation values for assessing the effect of insulation materials. The thermal conductivity indicates the amount of heat that passes through the building material.
For a material to act as an insulator, it should have a value below 0.1 W/mK. The rule is that the smaller the thermal conductivity, the better. Eco Friend Sheep’s wool insulation has a very good insulation value of 0.04 W/mK.
Effective sound insulation
Due to a different fiber fineness, sheep wool has very good sound absorption properties for many acoustic situations with high noise values.
For this good reason, our acoustic wool insulation products are increasingly demanded by architects, civil engineers and builders for kindergartens and schools, office buildings, function rooms and also by householders for the benefit of having a sound insulated home.
Regulates moisture
Sheep's wool has a hygroscopic effect, i.e., it binds moisture when the air humidity is higher than the compensating humidity of the wool. If the room air is too dry, it releases the moisture again.
Sheep’s wool can absorb up to 30% of its own weight in moisture without losing its insulating properties, without becoming damp. It also retains its bulkiness without having a damaging effect on the building fabric.
The reason for this is the unique structure of the protein fiber: water resistance. A property that is very advantageous, for example, for installation environments with high condensation. Another natural advantage of protein fiber is that it does not provide a breeding ground for mold.
Purifies the indoor air
Sheep wool naturally creates a healthy indoor climate and consequently promotes your health. Our natural sheep wool insulation is able to break down pollutants and odours.
The secret behind this excellent ability is keratin, the basic protein building block that makes up sheep’s wool. The molecules of the amino acid side branches can absorb pollutants such as formaldehyde and neutralize them. This results in a chemical reaction, whereby the pollutants are bound to these molecules or converted.
The closer sheep’s wool is installed to the interior, the better the positive effect on the indoor climate. For example, installation levels, partition walls and false ceilings with sheep wool insulation have a great effect on the indoor air.
