Kwabaninzi abatsha abatyali-mali, ukujoyina izixhobo zeglasi zokukhusela ubushushu kukubona amathuba amakhulu ophuhliso kunye namathuba amakhulu oshishino. Nangona kunjalo, abatyali-mali abatsha abaqhelananga noshishino, ngoko ke ukhetho lwabo lwezixhobo zeglasi zokukhusela ubushushu lusafuna ukuqwalaselwa ngononophelo. Kule meko, siza kufunda malunga notyalo-mali lwezixhobo zeglasi zokukhusela ubushushu ekufuneka luqwalaselwe.

amanqaku aphambili:

Okokuqala, nokuba kunjalo, abatyali-mali kufuneka baqonde ukuba ubungakanani bezixhobo zomgca wokuvelisa iglasi yokukhusela buhlukile okwangoku, oquka umgca omkhulu wemveliso, umgca wemveliso ophakathi kunye nomgca omncinci wemveliso. Umgca wemveliso wezixhobo zeglasi zokukhusela ezinkulu uquka umatshini wokugquma i-butyl, umatshini wokugoba iprofayili ye-aluminium, umatshini wokugquma iglasi, umatshini wokutywina ozenzekelayo wokucoca kunye nomatshini wokuzalisa isihluzo se-molecular. Umgca wemveliso ophakathi uquka ukucoca kunye nephepha, umatshini wokugquma i-butyl, itafile ejikelezayo, umatshini wokugquma iglasi kunye nomatshini wokuncamathelisa oneziqendu ezimbini. Umgca omncinci wemveliso uquka kuphela umatshini wokucoca iglasi yokukhusela kunye nomatshini wokugquma kunye nomatshini wokugquma i-butyl. Ixabiso elifakwayo lale migca yemveliso eyahlukeneyo lahlukile, nto leyo efuna ukuba abatyali-mali bakhethe umgca wemveliso ochanekileyo ngokwemali yabo.

Okwesibini, emva kokuba abatyali-mali begqibe ubungakanani bomgca wemveliso abawukhethayo, umsebenzi olandelayo kukukhetha izixhobo ezinokuthenjwa. Imfuneko yokusebenza komgca wemveliso kukuqinisekisa ukuthembeka kwayo, ukuqinisekisa ukuba ikhonkco ngalinye lecandelo kunye neenxalenye zidibene nenkqubo yangaphambili kakuhle, ukuze lonke iqela lingakwazi ukuyeka ukusebenza ngenxa yeengxaki kwikhonkco elithile. Kule meko, izixhobo ezisetyenziswa zizixhobo zeglasi ezingenanto kufuneka zicwangciswe phezulu, kwaye inkqubo kufuneka ihlale izinzile, ingakumbi iindawo eziphambili kufuneka zibe ziimveliso zophawu lwasekhaya olukumgangatho ophezulu okanye iimpawu ezingenisiweyo.

Ngokuphathelele ukukhethwa kwezixhobo zeglasi ezingenanto, singabhekisa kwezi zinto emva kokukhethwa kwemihla ngemihla, ukuze sikhethe izixhobo ezifanelekileyo, ezilungeleyo nezingcono ukuzisebenzisa.
