The above given deficiencies of the present insulating systems do not occur if the waste polyurethane is used as an insulating system of good quality bound with inorganic binders. This system is based on the principle that it contains 1 to 10 volume parts of polyurethane in the form of debris, the particles of which are sized 0.1 -20mm, further 0.1 to 10 volume parts of inorganic binders, e.g. cement, and/or lime, and/or gypsum, and/or lime hydro-silicates, and/or lime hydro-aluminates, and/or magnesia hydro-aluminates. The heat-insulating plaster further contains 1 to 20 volume parts of water. The heat-insulating plaster further contains 1 to 10 volume parts of gravel, and/or inorganic dusts the particles of which are sized 0.001 to 6 mm. |
