<p>A method of increasing the heat insulating capacity of a material such as a building component is achieved by including in the material a product which releases water at elevated temperatures. The product may be a water soluble crystallised compound in the form of a hydrate with two or more molecules of water, an inorganic hydrogel, or a combination of two or more hydrates or hydrogels, the hydrate or the hydrogel decomposing at a temperature in the range of from 40°C to 500°C inclusive to release water from the hydrate or the hydrogel to slow the progress of temperature elevation through the material.</p> |
