Wool is a highly effective insulating material which performs better than its rated R value because it can absorb and release moisture. [3] Mongolian nomads used [when?] felted and woven sheep wool pads as an insulating layer on the walls and floors of their dwellings, called ger or yurts. The use of wool for insulation is starting to rise in ...
Mineral wool is also known as mineral cotton, mineral fiber, man-made mineral fiber (MMMF), and man-made vitreous fiber (MMVF). Specific mineral wool products are stone wool and slag wool. Europe [who?] also includes glass wool which, together with ceramic fiber, are entirely artificial fibers that can be made into different shapes and are ...
Sheep's wool insulation is a very efficient thermal insulator with a similar performance to fiberglass, approximately R13-R16 for a 4-inch-thick layer. [22] Sheep's wool has no reduction in performance even when condensation is present, but its fire retarding treatment can deteriorate through repeated moisture. [23]
Don Magruder writes: "The advent of stone wool insulation is providing a unique value proposition for contractors and homeowners."
Steel wool may provide outstanding fire protection and can withstand heat up to 2150ºF. Paired with fire-rated drywall and other products, a homeowner or contractor can achieve 1-hour fire ...
Wood wool boards are rigid and very strong. Their thermal conductivity is higher than other insulation material between 0.070 and 0.100 W/(m.K) compared with mineral wool insulation materials to approximately 0.040 W/(m.K). But their specific thermal capacity and therefore summer heat insulation is higher than other materials, e.g. when ...
