Why Compressed Sheepswool inspires us:

With the days fast becoming shorter and the cold Autumnal air making a statement it’s time to pack the type of insulation you might see on a man called Del in Peckham… You will have to pay VAT on this, which is well worth it considering the unique advantage of sheepswool over man made insulation products. It is breathable and it can absorb (up to 33% of its weight without compromising its insulating ability) and release moisture from the surrounding air.

Why we like Compressed Sheepswool :

Compressed sheepswool insulation also has the ability to absorb and neutralise harmful substances. The wool is a natural protein made up of a 18 different amino acid chains. 60% of these have a reactive side chain, which allow the reactive areas of the wool to absorb harmful and odorous substances such as Nitrogen Dioxide, Sulphur Dioxide and Formaldehyde!

Thermafleece EcoRoll’s convenient compressed form reduces transport impacts by more than 50% compared withother natural insulations. Once unpacked, it regains its original thickness to provide excellent thermal and acoustic insulation. It is long lasting, safe to handle. This specific product has a breakdown of 75% wool blend, 15% recycled polyester and 10% polyester binder. If maintained correctly it should last upwards of 50 years.
