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

Why Insulate with Thermafleece?

Insulating a property will significantly reduce the amount of energy lost from the building envelope, reducing energy consumption and carbon dioxide released to the atmosphere. Wool is a sustainable and functional complex fibre with unparalleled insulating properties, designed by nature to insulate sheep in the harshest of environments, making wool the ideal natural fibre to use in thermal insulation.

First-class performance

Not only does Thermafleece provide excellent thermal insulation in a wide variety of constructions, it can be used in many acoustic applications. Thermafleece acts in sympathy with your property absorbing many indoor air pollutants and helping control humidity levels.

Long lasting

In order to ensure consistent thermal performance, it is important that insulation retains its shape throughout its service life. Thermafleece contains a lofting agent to maintain fibre stability and ensure the insulation batts maintain structural integrity throughout their lifetime. The manufacturing process ensures that each insulation batt is composed of a random matrix of wool fibres that will not split or delaminate in service.

Certified

Thermafleece is the only wool insulation to be certified by the British Board of Agremént (BBA). Certification by the BBA ensures Thermafleece is manufactured and performs to a rigorous set of standards. The certification covers installation between joists in ventilated and unventilated lofts; under pitched roofs and between rafters for tiled or slated pitched roofs, as well as timber frame wall applications between studding with a weather resistant cladding, and a ventilated and drained cavity. Environmental Excellence Using Thermafleece can reduce carbon emissions by many tones over the lifetime of use. Moreover, wool fibres fix carbon dioxide from the atmosphere helping reduce atmospheric greenhouse gas levels and making Thermafleece one of the most sustainable building materials currently available.

Safe

Thermafleece is safe to handle without the need for personal protective equipment.
