ABOUT SHEEP’S WOOL INSULATION
Sheep’s Wool – Thermal Efficiency
Sheep’s wool is hygroscopic and will therefore absorb and release water vapour without compromising its thermal efficiency. In cold weather, sheeps wool absorbs heat from moisture in the air which enables it to reduce heat loss from the building. In warm weather, the release of moisture has a cooling effect on the fibre which reduces the flow of heat into the building.
Physical Qualities of Sheep’s Wool
Sheep’s wool can be cut easily with a sharp knife or shears and requires no protective equipment to install. The quilt adapts to the shape of rafters, joists and studs to provide a permanently tight fit. When properly installed, it will retain its low density and thermal performance and have a life expectancy in excess of fifty years.
Fire Safety
Wool has a higher resistance to fire than cellulose and cellular plastic insulants. It melts when it comes into contact with an ignition source but should extinguish itself.
Thermal Performance of Sheep’s Wool
Sheep’s wool has insulating properties which are equivalent to mineral fibre insulation. A total thickness of 250mm, of the insulation material, when fitted in a loft floor will give a U-value of 0.16 w/m²k .
The low thermal conductivity of sheep’s wool batts is 0.039 W/m K at 10 degrees C which is similar to that of other fibrous insulants.
In the UK, when comparing the thermal values of insulating materials, it is important to remember that the best performing material is the one with the lowest thermal conductivity value.
