Icoil ye-asphalt ye-polymer ethandwa ngokuzithutha kwezikhethu zokugcina kanye ne-resin ethandwa ngokuzithutha kwe-asphalt enokuthuthukiswa kahle kanye nezinhlobo ezithile zezinto ezinokuthuthukiswa. Isimo sezindawo sikhombisa ifilimu ye-polyethylene (ifoili ye-aluminium noma isondo esincane) njengesimo semboni, futhi isimo sokuphenduka sikhombisa iphepha lokugcina elinokuthuthukiswa ngokuzithutha kwe-silicone oil noma i-coil enokuthuthukiswa ngokuzithutha kwezindawo ezincane ezincane njengesimo yomphenduka.
