Introduction
Thermafleece PB20 is a wool-based building insulation product by Second Nature UK Ltd, combining British sheep's wool and recycled polyester. It is designed for easy handling and installation, particularly in lofts, and offers significant energy-saving benefits.

Specifications
Thermafleece PB20 has a thermal conductivity of 0.042 W/mK and is available in compressed rolls, allowing for up to 60% compression. It is manufactured to ISO 9001 quality standards and is environmentally friendly, with zero global warming and ozone depletion potential.

Installation and Handling
The product is safe to handle without protective equipment, though a dust mask is recommended in enclosed spaces. It should be protected from prolonged sunlight and moisture. For cutting, it can be compressed between boards and cut with a sharp knife.

Performance
Thermafleece PB20 provides excellent thermal and acoustic insulation, contributing to energy savings and reduced carbon emissions. It is also effective in moisture and temperature control due to the hygroscopic nature of wool fibers.

Environmental Impact
The insulation uses wool from British hill sheep and recycled polyester, minimizing waste and carbon footprint. It is capable of fixing carbon from the atmosphere for at least 60 years.

Comparison with Thermafleece
Thermafleece PB20 is a lower density option compared to Thermafleece, which offers higher thermal and acoustic performance. However, PB20 is more compact and easier to transport and store.

Conclusion
Thermafleece PB20 is a versatile, sustainable insulation solution suitable for various applications, particularly where space and ease of installation are priorities.
