Weelka Dahaarka Silica Fudud wuxuu qaataa macdanta silica oo si fiican loo qaybiyay sida alaabta ceeriin. Cabbirka walxaha muhiimka ah kama badna 1mm, in ka badan 90% cabbirka walxaha ayaa ka yar 0.5mm. lebenka dahaarka silicate waxa lagu sameeyaa iyadoo lagu darayo walax gubanaysa culayska ama qaadashada habka xumbo gaaska si loo soo saaro qaab dhismeedka daldaloola ah iyada oo loo marayo toogashada, lebenka dahaarka silicate sidoo kale waxa laga dhigi karaa badeecad aan guban.
Culayska Fudud ee Silica Insulation Lebenku waxa uu alaabta ceeriin iyo biyaha gelinayaa qalabka wax lagu cajiiyo iyada oo loo eegayo qayb gaar ah ka dibna lagu cajiimay dhoobo, u qaabeeya dhoobada lebenka iyada oo loo marayo qaabaynta mishiin ama shaqaale. ka dibna qalaji lebenka ilaa inta ka kooban biyaha haraaga ahi ay ka hooseeyaan 0.5%, taas oo ka hortagaysa balaadhinta mugga isbeddelka kristaalka ah ee SiO2 oo dab ku shido lebennada qaabaysan heerkulka sare.

Lebenka dahaadhka ah ee silica waxaa loo isticmaali karaa foornada dhalada ah iyo kariyaha dabka kulul, block insulation block sidoo kale waxaa loo isticmaali karaa foornooyinka kookaha, foornada foornada kaarboonka iyo foornooyinka kale ee warshadaha.
