Felt is the traditional covering material for the yurt. Made by beating and rolling wet sheep’s wool. Felt has excellent insulation properties, keeping out the extremes of hot and cold experienced on the Central Asian steppe. Natural oils in wool make felt sufficiently waterproof for the fairly dry climate of Central Asia. For our climate the felt is used as an insulating layer under the waterproof canvas cover. Felt is only suitable for yurts which are regularly heated.
