Sheep’s Wool for Log Homes – 100 % virgin wool, natureplus certified

Looking for an insulation alternative made from virgin wool rather than synthetic materials?

Discover our sheep’s wool insulation for log home construction!

Available in convenient 10 kg bags: 100 % virgin sheep’s wool with a thermal conductivity of 0.039 W/mK, natureplus certified under number 0103-1006-099-1.

Processing & Installation

The installation is quick, with no waste or dust, and is particularly suitable for overhead work.
The insulation rolls are installed from bottom to top, and the surface felt is attached to the wooden structure by side stapling.
It is possible to cut the material either manually by tearing or using the ISOLENA cutting device.

Wool Protection

IONIC PROTECT® is a biological and biocide-free wool protection process that has been tested for long-term efficacy according to EAD standards and is protected by trademark patent law.
Through plasma treatment, the structure of the protein molecules in the wool is altered in a way that no longer serves as food for pests.
The wool protection is tested to EAD 040005-00-1201 for resistance to clothes moths and carpet beetles.

Thermal conductivity 0.039 W/mK

Sheep’s wool insulation keeps the warmth inside the house. The thermal conductivity of the wool is 0.039 W/mK — the lower this figure, the less heat is lost through the construction. The value is stated in natureplus certificate 0103-1006-099-1.

Absorbs moisture and releases it again

Sheep’s wool absorbs moisture from the indoor air and releases it again. This evens out fluctuations in humidity within the construction and the room.

Tested and certified

The wool carries natureplus certificate 0103-1006-099-1. The label is awarded by an independent body against fixed test criteria, not by the manufacturer. What we supply is 100 % virgin sheep’s wool — without supporting or bonding fibres and without biocides.

Advantages

The Benefits of Sheep’s Wool

Offers excellent insulation properties

The virgin sheep’s wool reaches a thermal conductivity of 0.039 W/mK, putting it in the range of common mineral and wood fibre insulation — in a material that needs no supporting fibres and no biocides.

Reaction to fire E-s1, d0

Tested to EN 13501-1: reaction to fire E, smoke production s1, no flaming droplets (d0). The fibre ignites only at 560 to 600 °C — about twice the figure for wood (270 °C) — and retreats from the heat source when exposed to heat.

Moisture Regulation

Sheep’s wool is capable of absorbing up to 33% of its own weight in moisture without compromising its insulation performance. In a dry environment, the moisture is released from the wool.

Processed without biocides

The wool is finished without biocides. Wool protection is applied by plasma treatment (IONIC PROTECT®), tested to EAD 040005-00-1201.

Effective Soundproofing

Due to the different fiber fineness of the wool fiber, sheep’s wool offers excellent sound absorption properties, making it an excellent choice for demanding acoustic enhancements.
