A short Guide to Sheep wool insulation
Wool insulation is made from Sheep wool fibres which are either bonded using recycled polyester or are mechanically held together to form rolls, ropes and batts. Sheep wool insulation is also known as wool insulation, natural insulation or fibre insulation. Natural sheep wool insulation is effective for both acoustic and thermal insulation.
Sheep wool insulation is a natural, recyclable, biodegradable and sustainable material. Wool insulation causes no issue to the health of people or the environment, it does not require any protective wearing while installation like fibreglass insulation. To decrease heating bills and reduce the heating cost you need to insulate your home. Sheep wool is nature's most effective insulator and has a crimped nature, which helps to form millions of tiny air pockets while packing or bonding wool fibre to trap air.
The environmental benefits of sheep’s wool insulation are many. Each kg of natural fibre product locks up about 2-3 kg of carbon dioxide which helps remove CO2 from the atmosphere. Thermal Conductivity of sheep wool insulation is between 0.035-0.4 W/mK which makes sheep wool a better insulator. Sheep wool insulation can be used throughout the entire house from loft, floors, external walls and internal walls.

Sheep wool material can absorb and release moisture without losing any of the thermal qualities. Sheep wool will keep its insulation value even if moisture is present in the building. Sheep's wool is hygroscopic, so it can absorb around 25% of its own weight in moisture before its thermal efficiency drops. This ability to absorb water helps control humidity levels and reduces condensation within your home.
