Fibre structure

Cellulose Mainly manufactured from recycled newspapers. Manufactured into fibres, batts or boards. Treated with fire retardant and pesticides.

Lambda value 0.038-0.040 W/mK.

Sheep's wool Must be treated with a boron and a fire retardant. Disposal may have to be at specified sites. Lambda value 0.040 W/mK.

Flax Treated with polyester and boron. Lambda value 0.037 W/mK.

Straw Heat treated and compressed into fibre boards. Treated with fire retardant and pesticide. It can be used as a wall material with a high thermal efficiency. In its present day form it should be much more reliable than the strawboard of the 1960s which had a tendency to germinate. Lambda value 0.037 W/mK.

Hemp Under development as a compressed insulation board. A highly eco-friendly material, grows without needing pesticides and produces no toxins. Initial tests have used hemp as a building material mixed with lime and placed like concrete. Test houses have proved as thermally efficient as identical well-insulated brick built houses built alongside the hemp examples.
