<p>Inorganic wools or fibres opened up by a carding, to which granules of perlite are added, are mixed with bonding agents in the dry state and the mixt. is conditioned in sacks. The different characteristics of the separate materials are maintained, and the product can be sprayed on walls and other structures together with an adhesive or possibly water. The mixt. forms a layer with good thermal and acoustic insulating characteristics together with anti-condensation and fire-repellant qualities.</p> |
