Thermafleece - a more natural insulation material developed by Second Nature UK Ltd using the wool of British hill sheep. An exceptionally efficient insulation in both new-build and refurbishment projects, which is absolutely safe to use. With its ability to rapidly absorb and release water vapour, Thermafleece can help to keep buildings cool in summer and warm in winter. Thermafleece has BBA accreditation and approval by the Energy Savings Trust as an energy savings product. With a life expectancy similar to the building in which it is installed and then recyclable, it’s the effective solution and the natural choice.
