Thermafleece PB20 – A Lifetime of Performance
Thermafleece PB20 is a wool-based building insulation incorporating a recycled polyester bulking agent to enable the insulation to be rolled and compressed by up to 60% whilst retaining many of the functional and environmental benefits associated with wool fibres such as breathability and carbon fixation.
Thermafleece PB20 is available in packs of 2 or 3 compressed rolls that are easy to store, easy to handle and easy to install making it the ideal solution for applications such as lofts.
Why Insulate With Thermafleece PB20?
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. Thermafleece PB20 contains 60% British sheep’s wool combined with recycled polyester to provide a versatile compressed insulation with thermal performance equal to or better than many conventional materials.
Versatile
Not only does Thermafleece PB20 provide excellent thermal insulation, it can be used in many acoustic applications, it acts in sympathy with your property absorbing many indoor air pollutants and helps control humidity levels.

Long Lasting
In order to ensure consistent thermal performance, it is important that insulation regains its thickness when unrolled and retains its shape throughout its service life. Thermafleece PB20 contains a lofting agent to maintain fibre stability and recycled polyester fibres that ensure the insulation regains its thickness when unrolled. Moreover, the manufacturing process ensures that each roll of insulation is composed of a random matrix of wool and recycled polyester fibres that will not split or delaminate in service.

Technical Specification
Thermal Performance
Thermafleece PB20 is manufactured using state of the art techniques to produce a tightly bound random matrix of hollow wool fibres and recycled polyester with a large internal surface area that ensures the finished insulation has excellent thermal insulating properties.
Thermafleece PB20 is manufactured using state of the art techniques to produce a tightly bound random matrix of hollow wool fibres and recycled polyester with a large internal surface area that ensures the finished insulation has excellent thermal insulating properties.
Thermafleece PB20 has a nominal density of 20kg/m3 and a thermal conductivity of 0.042 W/mK which is better than most equivalent conventional insulation.
Acoustic Performance
Thermafleece PB20 can be used in many applications outlined in Approved Document E, contributing to the reduction in the passage of sound in structures in line with current UK Building Regulations and Robust Details.
As part of the overall sound reduction measures the use of an appropriate absorbent material such as Thermafleece PB20 to fill wall voids will make a valuable contribution towards passing required acoustic tests under the regulations.
Moisture & Temperature Control
The hygroscopic nature of wool fibres means that Thermafleece PB20 can act in sympathy with buildings to control internal moisture levels and contribute to a more stable and comfortable indoor environment.
When the wool in Thermafleece PB20 encounters moisture it is capable of releasing and absorbing heat. Wool releases heat when absorbs moisture and absorbs heat when it releases moisture which can have a stabilizing influence over air temperature.
Fire Resistance
Thermafleece PB20 is treated with a low level of borate fireproofing agent to improve its intrinsic fire resistance and comply with BS 5803-4 achieving a pass for flammability and smoldering resistance.
