Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
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 ...

Foam glass is fireproof, waterproof, non-toxic, corrosion-resistant, non-aging, non-radioactive, and insulating. It is a stable building exterior wall and roof insulation and sound insulation material. Foam glass does not absorb water. The cells are mostly closed, so there is no capillary rise.
Common insulation applications in an apartment building. According to a mineral wool manufacturer, the first mineral wool intended for high-temperature applications was invented in the United States in 1942 but was not commercially viable until approximately 1953. More forms of mineral wool became available in the 1970s and 1980s. [4]
Depending on metal prices, copper may be a very cost-effective cladding and roofing material. With good building design, materials choice and craftsmanship , copper roofing or facade cladding may be cheaper than slates or concrete tiles, especially when one takes into account the lasting colour , durability, maintenance -free and lightweight ...

It has a thermal conductivity of 0.038–0.08 W m −1 K −1, which is comparable to other wood fibre insulation materials. To achieve the same thermal insulation efficiency as other more insulating materials such as extruded and extended polystyrene, the thickness of the straw insulation layer should be increased by 30–90%.
