Safe & healthy Comfort is a safe material, not only to handle and install, but to have within your home. Wool fibres are completely safe to touch and work with, requiring no special handling or protective equipment. Comfort insulation rolls can be installed on top of existing glass or mineral wool, reducing the opportunity for their potentially hazardous particles to become airborne. Due to it's high moisture content, wool does not support combustion and will extinguish itself when the source of flame is removed. In the event of a fire, wool is a much safer material than man-made products as it does not release poisonous fumes.  Environmental benefits Sheep Wool Insulation products have unrivalled environmental credentials, making it them the "greenest" choice of any insulation product on the market. Sheep's wool is a naturally occurring fibre, so it is a renewable and sustainable source of raw material. Wool has zero global warming potential and is carbon neutral, so choosing Comfort means your insulation will have no environmental impact. Sheep Wool Insulation also requires only a fraction of the energy to produce in comparison to other insulation materials. At the end of its useful life, Comfort can be reused as insulation, recycled into other wool products or buried where it will eventually biodegrade.

As the lowest priced pure wool fibre insulation in the world, Comfort leads the way in giving homeowners, builders and professionals the choice to use natural materials in their projects. Being produced in both 100mm and 150mm thick rolls, Comfort needs less layers layers to meet modern building regulations, saving time and even more money during installation.
