Sheepwool Insulation

Show business description


We have been wool merchants for over 150 years, so we truly understand the huge benefits which can be gained from using natural, pure wool as an insulation product.

SheepWool Insulation is made from and contains only 100% Pure SheepWool - we do not use any polyester or binder, just 100% pure Wool, - healthy, natural and breathable.

There are a huge amount of benefits from using 100% pure, natural wool as an insulation product - and this is primarily down to its breathability - it is not only an excellent insulation product, but it also absorbs moisture, engages in air purification, has excellent sound absorption properties, as well as being very safe in the event of fire.

This is a totally natural, breathable range to allow your building to breathe so that you can enjoy a natural, healthy insulation. Keeping your building warm in winter as well as cool in summer – just as nature intended.


We have a full range of insulation and acoustic underlay products, all made from and containing only 100% Pure SheepWool.
