Na silicate e thata ea calcium e sebelisoa e le thepa ea ho kenya letsoho indastering ea tšepe e seng ferrous? Indasteri ea tšepe e se nang ferrous (joalo ka aluminium, koporo, lead, smelting ea zinki le ts'ebetso), lisebelisoa tsa mocheso o phahameng (lisebelisoa tse qhibilihang, libono tsa ho kenya letsoho, liteishene tsa phallo, lisele tsa electrolytic, joalo-joalo) li na le litlhoko tse thata ka ho fetesisa bakeng sa lisebelisoa tsa insulation: ho hanyetsa mocheso o phahameng, conductivity e tlase ea mocheso, ho hanyetsa khoholeho ea tšepe, ha ho na tšilafalo le mokelikeli oa tikoloho. Ka indasteri ea tšepe e se nang ferrous, silicate e thata ea calcium, e le thepa ea ho kenya letsoho, e na le melemo ea mantlha e kang ho hanyetsa mocheso o phahameng, mocheso o tlaase oa mocheso, botsitso bo phahameng, bophelo bo bolelele ba tšebeletso, tšireletso ea tikoloho le polokeho. E ka ntlafatsa katleho ea matla a lisebelisoa, ea fokotsa litšenyehelo tsa tlhokomelo le ho netefatsa tlhahiso e sireletsehileng.

Na lebota la kantle le nang le karolo e ka ntle ea aluminium foil rock wool board ke 20mm? Boto e entsoeng ka aluminium e entsoeng ka lejoe la rock (botenya ba 20mm) ke boto ea ho kenya letsoho e entsoeng ka boea bo phahameng ba hydrophobic rock e le thepa ea mantlha, e nang le lehlakore le le leng kapa ka bobeli le koahetsoeng ka foil ea aluminium e khanyang haholo (hangata e kentsoeng ka foil ea aluminium). Hangata e sebelisoa bakeng sa ho thibela mocheso, ho thibela mongobo, le ho boloka matla libakeng tse nang le sebaka se fokolang.
