thermal insulator with a higher performance than traditional glass fibre, it is also proven to absorb and neutralise harmful substances. The wool is a natural protein made up of a number of different amino acid chains (18 to be exact), 60 per cent of which have a reactive side chain. These reactive areas allow the wool to absorb harmful and odorous substances including nitrogen dioxide, sulphur dioxide and formaldehydes, and neutralise them through a process known as chemisorption. Sheep’s wool also has the benefit of a
hygroscopic (moisture-absorbing) core which enables it to absorb 33 per cent of its weight in moisture from the air without compromising its insulating ability. This makes it the ideal choice in the loft space, where more condensation is likely to be encountered. The objection is often raised that the higher
U-value of eco insulation products compared with their conventional counterparts can prove a challenge for contractors who are required to hit demanding Building Regulations, but the solution to this is straightforward. Increasing the thickness and amount of material leads to the U-value being vastly improved, and pairing the insulator with a breather membrane can further aid in the meeting of specifications. For those seeking a true eco-specification we recently added a new range of sheep wool
insulation to the line-up, which is 100 per cent pure and treated with Ionic Protect – a biocide free, CUAP tested treatment that protects against moth infestation for life. The growth in uptake of such products shows that the trend towards eco insulation is a rapidly growing and sustained one, paired with innovation which is continuing to improve the options available to the market.
