For over 17 years, Thermafleece has been the UK’s leading brand of natural and sustainable insulation. Launched in 2000 Thermafleece was the UK’s first British sheep’s wool insulation
Here at Natural insulations we offer:
Thermafleece CosyWool in Roll Form: A versatile insulation rich in British sheep’s wool which is easy to install between and over joists, ideal for floors and lofts and is the perfect choice if you are looking for all round performance and value for money
Thermafleece CosyWool in Slab Form: Great for insulating walls and roofs. CosyWool Slabs are flexible but denser than rolls and sized to provide extra tight friction fit in walls and roofs providing excellent thermal and acoustic performance.
Thermafleece UltraWool: A high density ultra-efficient insulation rich in sheep’s wool and is the ideal choice if you are looking for maximum thermal performance when space is at a premium. What’s more, with its higher density Thermafleece UltraWool helps provide exceptional acoustic insulation performance in wall, floor and roof systems.
Thermafleece NatraHemp: Rich in hemp fibres – Natrahemp can be used in most situations where plant fibres are preferred. Hemp is a fast-growing, low-impact plant crop that produces fine fibres suitable for insulation. Thermafleece NatraHemp is a medium density insulation rich in hemp fibres and is a safe, efficient and durable alternative when plant fibre is the preferred choice.
A truly British Company based in the heart of the Cumbrian Lake District, Thermafleece products are created and manufactured in the UK and use only British Wool.
