Thermafleece Insulation

Wool is a natural fibre from a fully renewable resource, consequently the life cycle of the product has an ideal energy balance. THERMAFLEECE is manufactured to a density of 25kg/m3 giving a K-value of 0.039 W/m.K. 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
When the outside temperature increases and begins to heat the wool, it releases moisture; that has a cooling effect on the fibre which reduces the flow of heat to the inside of the building. This can reduce peak temperature by up to 7 c when compared to buildings in which alternative forms of insulation are installed.

WARM IN WINTER
In the winter the absorption of moisture by wool insulation can increase peak temperature by up to 4 c when compared to buildings in which alternative forms of insulation are installed.

THERMAFLEECE is harmless and can be installed without gloves or protective clothing. It is not irritating to the skin, eyes or respiratory tract and causes no discomfort to site workers during installation. Any fibres which happen to reach the living space will present no hazard to health. The necessary insect proofing and fire resistance rating is achieved by the inclusion of naturally derived additives.

EXTREMELY DURABLE
The fibre adapts to the shape of 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.

RECYCLABLE
At the end of its useful life, THERMAFLEECE can be recycled for other environmentally friendly applications. THERMAFLEECE contains no permethrin, pyrethroids, pesticides or formaldehydes.
