The classification temperature does not mean that the product can be used continuously at this temperature. In the field, the continuous application temperature of amorphous high-temperature mineral wool (AES and ASW) is typically 100 °C to 150 °C below the classification temperature. Products made of polycrystalline wool can generally be ...
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 ...

Inherently fire-resistant, or proprietary factory assembled ducts which are made of sheet metal shells filled with mixtures of rockwool, fiber and silicon dioxide Sheet metal duct with exterior fireproofing materials such as blanket rockwool, ceramic fiber, or intumescent paint .
Calcium silicate competes in these realms against rockwool and proprietary insulation solids, such as perlite mixture and vermiculite bonded with sodium silicate. Although it is popularly considered an asbestos substitute, early uses of calcium silicate for insulation still made use of asbestos fibers.
One example is AirKrete, [5] at R-3.9 (RSI-0.69) per inch and no restriction on depth of application. Non-hazardous. Being fireproof, it will not smoke at all upon direct contact with flame, and is a two-hour firewall at a 3.5 in (89 mm) (or normal 2 in × 4 in (51 mm × 102 mm) stud wall) application, per ASTM E-814 testing (UL 1479).
