Thermafleece
Thermafleece has been the UK’s first choice of sheep’s wool insulation since it was launched in 2001. Thermafleece is a high density, wool rich insulation that is the first choice when maximum thermal and acoustic performance and breathability are required or in space limited situations.
Manufactured to meet the highest quality and performance standards and using British sheep’s wool, Thermafleece is the only wool based insulation to hold BBA certification.
Thermafleece has a thermal conductivity of 0.038 W/mK and is available in a variety of dimensions suitable for all your application needs.
Thermafleece is supplied in slab form with standard lengths of 1200mm with three thicknesses, 50mm, 75mm and 100mm and two widths, 400mm and 600mm.
Thermafleece PB20
Thermafleece PB20 is as a lower density, compressed roll insulation that is easy to handle and install in confined spaces such as lofts. Thermafleece PB20 contains a lower quantity of wool than Thermafleece (60% compared to 85%).
Because Thermafleece PB20 is compress packed, it is necessary to incorporate a proportion of recycled polyester fibres to ensure the insulation regains its full thickness when un-rolled.
Compressing the rolls by approximately 60% significantly reduces the impact of transporting the finished product and nearly halves the required storage space for the same volume of insulation.
Thermafleece PB20 has a thermal conductivity of 0.039 W/mK and is available in roll form in widths of 370mm and 570mm to enable quick and easy installation. Each roll contains a single 5.3m length of insulation and is available in a thickness of 70mm and 100mm.
