What Is Thermafleece UltraWool Insulation? 

The primary purpose of insulation is to regulate temperature and conserve energy, and Thermafleece UltraWool excels in this aspect. 


Its unique blend of natural fibres ensures excellent thermal insulation, effectively reducing heat loss during the colder months and minimising heat gain during warmer periods.

Another noteworthy feature of Thermafleece UltraWool insulation is its moisture regulation capabilities. 

The inherent breathability of sheeps wool insulation allows moisture vapour to escape, preventing condensation buildup within walls and roofs. 

This not only safeguards the integrity of the building's structure but also contributes to better indoor air quality and reduces the risk of mould and mildew formation.

What's more, UltraWool's natural sheep wool composition ensures a hazard-free installation process which does not necessitate the need for protective clothing or a dust mask.
