<p>This invention relates to a new compound to be used as insulatinq material, e.g. as heat and fire insulation in house construction. The new material of the present invention is a material insulating against and thus operating in cold as well as heat, it does not cause damage at fires (i.a. no poisonous gases being developed), it does not shrink and has good adhesion, which gives a practical ?-value that substantially agrees with the theoretical one, it is environmental non-hazardous, i.e. it does not contain any poisonous substances, and it is easy to inject and in practice useful at working sites, without necessitating the use of complicated equipment. The new material of the invention comprises a mixture of water, binder, wetting agent, water glass, mineral wool, expanded vermiculite and optionally ammonia. The material is characterized in that it comprises a mixture of 250-1500 parts by weight of water, 5-70 parts by weight of binder, 1-10 parts by weight of anionic or cationic wetting agent, 10-100 parts by weight of mineral wool, 30-300 parts by weight of expanded vermiculite, optionally 1-10 parts by weight of ammonia, and optionally a difficultly fusible ballast material.</p> |
