Description
Description
Thermafleece UltraWool is a high density ultraefficient insulation rich in British sheep’s wool and is the ideal choice if you are looking for maximum thermal performance when space is at a premium.
With a density of 31 kg/m3 Thermafleece UltraWool also helps provide exceptional acoustic insulation performance in wall, floor and roof systems.
Research shows that using 75% wool in combination with recycled fibres outperforms alternative products with a higher percentage of wool. Our wool rich blend ensures you get the full benefit of sheep’s wool with enhanced performance, durability and sustainability.
Like all Thermafleece products, it is long-lasting, safe to handle and contributes to a healthier indoor environment by regulating moisture and absorbing harmful airborne substances in the home.
Why Insulate with Thermafleece UltraWool?
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.
High Performance
With a Thermal Conductivity of 0.035 W/mK,
Thermafleece UltraWool is the best performing natural
fibre-based insulation on the market.
Cost Effective
Energy savings from using Thermafleece UltraWool
mean it can pay for itself in a few years.
Long Lasting
Thermafleece UltraWool contains a lofting agent to
maintain durability, fibre stability and structural
integrity.
Sustainable
Thermafleece UltraWool can reduce CO2 emissions by
many tonnes over the lifetime of use. Wool also fixes
carbon dioxide helping reduce greenhouse gas levels.
Safe
Thermafleece UltraWool is safe to handle and can be
recycled or safely disposed of at the end of its life.

Installation and Handling
Thermafleece UltraWool is non-hazardous and can be
handled without protective clothing, although we
recommend you wear PPE in spaces such as lofts.
Protect the insulation from prolonged exposure to
sunlight when unpacked and avoid wetting, store
under cover and clear of the ground.
If the insulation gets wet during storage or as a result
of flooding in service, remove the affected insulation
and replace with new.
When installed in walls and floors, spaces filled with
UltraWool should be considered as concealed voids for
the purposes of fire risk and cavity barriers installed
as appropriate. Thermafleece UltraWool is not
suitable for use as a cavity barrier
