Thermafleece utilises hollow wool fibres, blended to an optimum density, producing first class thermal and acoustic performance in buildings whilst minimising the impact on the environment.

Wool is a sustainable and functional complex fibre with unparalled insulating properties, designed by nature to insulate sheep in the harshest of environments, making wool the ideal natural fibre to use in thermal insulation.

Manufactured in the UK using British sheep's wool, Thermafleece meets the highest quality and performance standards and is the only wool based insulation to hold British Board of Agrèment (BBA) certification.
