Thermafleece British Sheepswool Thermal and Acoustic Insulation
Thermafleece is a highly thermally efficient insulation and is the only British wool insulation to be BBA certified - (02/3950). Meaning that it totally complies with Building Regulations, in between joists in ventilated and unventilated lofts; under pitched roofs and between rafters for tiled or slated pitched roofs, as well as timber frame wall applications between studding with a weather resistant cladding, and a ventilated and drained cavity.

Thermafleece is made using the wools from sheep that graze the upland areas of the UK, breeds such as Swaledale, Herdwick, Scotch Blackface and Welsh Mountain to create an exceptionally efficient thermal and acoustic building insulation.

Why Wool Insulation is Best
Wool is a natural fibre from a fully renewable resource; consequently the life cycle of the product has an ideal energy balance. Because of its ability to rapidly absorb and release water vapour Thermafleece wool insulation can help to keep buildings cool in summer and warm in winter.

Cool in Summer and Warm in Winter
When the outside temperature increases and begin to heat the wool, it release moisture: that has a cooling effect on the fibre that reduces the flow of heat to the inside of the building. This can reduce peak temperature by up to 7 degrees c when compared to buildings in which alternative forms of insulation are installed. In the winter the absorption of moisture by wool insulation can increase peak temperature by up to 4 degrees c when compared to buildings which alternative forms of insulation are installed.

Naturally Breathable
Thermafleece can absorb and desorb water vapour without compromising its thermal efficiency. It is therefore ideal for use in roofs and timber framed walls designed to avoid a damaging build-up of moisture by allowing water vapour to migrate through the structure.

Condensation Control
Wool generates heat when it absorbs moisture from the air. That energy is known as the heat of sorption and accounts for the warmth felt by wearers of woollen clothes in winter conditions.

Energy Efficient, Totally Safe
The cleansing, air-laying and thermal bonding processing during the manufacture of Thermafleece consumes minimal energy. Thermafleece uses only 14% of the embodied energy that is used to manufacture glass fibre insulation, therefore paying back its manufacturing energy cost seven times faster than glass fibre.

Extremely Durable & Recyclable
The fibre adapts to the shape of the rafters, joists and studs to provide a permanently tight fit. Properly installed, Thermafleece will retain its low density and thermal performance - with a life expectancy similar to that of the construction in which it is installed. At the end of its useful life, Thermafleece can be recycled for other environmentally friendly applications; Thermafleece contains no permethrin, pyrethroids, pesticides or formaldehydes.
