Second Nature ‘Thermafleece’
Wool thermal insulation rolls
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.'
