Peat and moss are traditional insulating materials used in log construction. Peat fibres are lightweight, porous and mostly hollow, which gives them a good natural heat insulation capacity.
Combined with the modern manufacturing techniques used to produce insulating materials, peat fibre can be refined into easy-to-handle insulating sheets whose dimensions match construction standards. They do not cause itching during installation and they do not sag.
It is not uncommon to discover old peat-insulated wood roofs and base floors in good condition during building renovations. With peat preventing the growth of bacteria and fungi, the wood structures remain healthy from one decade to the next as long as they have not been exposed to rainwater or capillary water. Peat fibre is hydrophobic, which makes the insulating material breathable and quick-drying.
