Second Nature UK manufactures Thermafleece from British hill sheep wool to create a very efficient insulation material in both new build and refurbishment projects which is absolutely safe to use. Wool is a natural fibre from a fully renewable resource. 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
