Sheep's Wool is a renewable and totally natural form of insulation. After all, we have woven clothing from wool for thousands of years, why not insulate our homes and office building with it as well?

Sheep's wool, provided it is not imported from long distances, has a very low level of embodied energy, since unlike many other insulation materials it is a natural product manufactured without any input energy, and is processed with only minimal energy consumption.

The ability of wool to rapidly absorbs and release water vapour (up to 40% of its weight) without any loss of efficiency, makes it a partially effective natural home insulation material, keeping buildings cool in summer and warm in winter.

Sheep's wool has thermal conductivity of between 0.037 W/mK - 0.040 W/mK.

Sheep's wool not only has exemplary insulation qualities and is on par with the best manufactured products, it is safe to handle, omits no gasses or fumes or irritable mineral fibres so common with glass wool styled products.

Hemp

Hemp is another renewable low embodied energy insulation material. Since 1996 the cultivation of low-narcotic hemp has been permitted in some parts of Europe, mainly Holland and Germany. As hemp production is rather limited the cost of it can be prohibitive if only relatively small areas of insulation are required.

During hemps growth it assists in cleaning the air and reducing envioromental potution as it absorbs and decomposes carbon dioxide (C02) from the atmosphere.

Hemp's insulation properties are similar to that of sheep's wool. Hemp has a high natural content and is recyclable and totally biodegradable in content. It is also a natural insect repellent, however for it to meet safety standards for building construction it does have chemicals added to retard fire.
