Product Description

Thermafleece CosyWool is an ideal insulation solution if you're looking for an environmentally friendly product that is easy to install and made in the UK. Suitable for use in roofs, walls, floors, CosyWool is also highly breathable, which helps to improve the health of the building and its occupants. Just two layers of 140mm will be enough insulation in your loft to start making your energy usage more efficient. CosyWool's density also means it is suitable to achieve some airborne sound reduction through walls, floors and roofs.

Its also much easier and safer to install compared to traditional insulation. CosyWool doesnt irritate the skin, eyes or get into your respiratory system and can be installed without gloves. We do recommend using a face mask when installing in lofts due to the dust particles that may be kicked up during installation.
