Iphaneli yokuxhasa idlala indima ebalulekileyo ekwakheni iindonga zamakhethini. Okokuqala, inika inkxaso, ukubonelela ngesakhiwo esizinzileyo sokwakheka kweepaneli zodonga lwamakhethini, ukuqinisekisa ukuba zihlala zithe tyaba kwaye zizinzile ngexesha lofakelo kunye nokusetyenziswa, kunye nokuthintela ukuguqulwa okanye umonakalo kwimikhosi yangaphandle. Ngokomzekelo, kwiindonga ezinkulu zamakhethini eglasi, iipaneli ezixhasayo zinokuchitha amandla angaphandle njengemithwalo yomoya kwiipaneli zeglasi, okwenza iglasi ikhuseleke kwaye inokwethenjelwa. Okwesibini, iipaneli ze-backer zibonelela nge-thermal insulation, ukunciphisa ngokufanelekileyo ukuhanjiswa kobushushu phakathi kweendawo zangaphakathi nangaphandle kunye nokunciphisa ukusetyenziswa kwamandla kwisakhiwo. Bavimba ubushushu belanga ekungeneni kwisakhiwo kwaye, ebusika, bathintele ukulahleka kobushushu, baphucule ukusebenza kakuhle kwamandla kwesakhiwo. Ngaphezu koko, iipaneli ezixhasayo zibonelela ngokugquma kwesandi kunye nokunciphisa ingxolo, ukuthintela ingxolo yangaphandle ekungeneni kwisakhiwo kunye nokudala indawo ezolileyo. Ekwakhiweni kweendonga zekhethini ezibekwe ecaleni kwezitrato zedolophu ezixakekileyo, iiphaneli ezixhasayo zinokunciphisa kakhulu ifuthe lengxolo eveliswa zizithuthi kunye nezinye izinto. Ngaphaya koko, iipaneli ezixhasayo zongeza ukuxhathisa kodonga lomkhusane. Ezinye ii-backer panels zenziwe ngezinto{8}}ezikwaziyo ukumelana nomlilo, ezinokucothisa ukusasazeka komlilo xa kuthe kwatsha, ukuthenga ixesha lokuphuma kunye neenzame zokuhlangula umlilo. Ekugqibeleni, ibhodi yokuxhasa inceda ukuphucula ukusebenza kwamanzi odongeni lwamakhethini. Inokuthintela amanzi emvula ukuba angene ngaphakathi kwodonga lwamakhethini, ukukhusela isakhiwo sodonga lwamakhethini kunye nengaphakathi lesakhiwo ekukhukulisekeni kwamanzi.
