Ugwebu lwe-silicone ye-fiberglass inomgangatho ophezulu wokuxhathisa-ubushushu bogwebu oluqhelekileyo lwesilicone. Ngenxa yobukho boluhlu lwezinto zeFiberglass, iipropati zayo ezingaphezulu zingatshintshwa. Inamandla okumelana nokukrazula, ukutyibilika okugqwesileyo kunye neempawu zokuzithambisa{3}} kumphezulu, kunye nokuxhathisa okuqinileyo kweenyembezi. Ukumelana nomhlwa kunye neempawu ezichasayo{5}}ukuguga zibalasele ngakumbi, kwaye iyakwazi ukuxhathisa ukhukuliseko lwemichiza eyahlukeneyo.
I-fiberglass igwebu lesilicone ithandwa kakhulu kumzi mveliso wamandla amatsha ngenxa yeempawu zayo ezizodwa kunye nokusebenza okubambezelekayo komlilo{0}}. I-foam ye-silicone ye-fiberglass inokuhlangabezana neemfuno ezingqongqo zobuchwephesha zale ntsimi. Esi sixhobo akulula ukusikrazula kwaye sinokuphinda sisetyenziswe. Isebenza kakuhle kakhulu, ayinadangatye{4}}iyadelela, ayinamanzi kwaye iyamelana nokubola kwemichiza.
I-Sanpu inokubonelela ngesisombululo esinye sokumisa usetyenziso lwale mveliso kwimiba efana ne-buffering kunye nokugqunywa kobushushu phakathi kweeseli zebhetri, ukutywinwa kwebhokisi, kunye nokukhuselwa kwe-thermal ebalekayo, ukubonelela ngesiqinisekiso esiqinileyo sokusebenza ngokuzinzile kwezixhobo zamandla amatsha.
