Ngokukhuthazwa kweenjongo zaseTshayina "ezimbini zekhabhoni", ukonga amandla kunye nokunciphisa ikhabhoni kwizakhiwo kuya kugxininiswa ngakumbi.Iindawo ezininzi zithintele okanye zithintele ukusetyenziswa kwe-insulation yangaphandle eludongeni, i-plaster encinci yangaphandle yodonga lwangaphandle kwizakhiwo eziphakamileyo, kunye nodonga lwangaphandle olusisigxina kuphela nge-anchoring anchoring.Izinto eziluncedo kwisangweji ehlanganisiweyo esenziwe ngaphambili egqunywe iindonga zolusu oluphindwe kabini (ezaziwa ngokuba ziindonga zolusu oluphindwe kabini ezinomaleko wokugquma) ziya zibonakala.

Isandwich ehlanganisiweyo esele ilungisiwe igqunywe iindonga zolusu oluphindwe kabini ngamacandelo ephaneli yodonga eyenziwe ngamacandelo amabini enziwe ngamatye ekhonkrithi eyomeleziweyo adityaniswe zizihlanganisi ukwenza ipaneli yodonga enomqolo ophakathi ngeenjongo zokugquma.Emva kokufakwa kwendawo, i-cavity igcwele ikhonkrithi egalelwe ukwenza udonga olunomsebenzi we-insulation.

I-sandwich edibeneyo edibeneyo efakwe kwiindonga zolusu oluphindwe kabini ayifuni imikhono ye-grouting, ngokufanelekileyo ukunciphisa ubunzima bokwakha kunye neendleko zokwakha.Zineenzuzo ezifana nokuxhathisa umlilo, ukuxhathisa idangatye, akukho kukhula komngundo, kunye nokugquma kwe-thermal.
