Izakhiwo zezakhiwo zamaplanga zithandwa kakhulu eYurophu naseMelika eziphantse zahlala kwi-90% yendlu yokuhlala (indlu enye okanye iVilla).Ngokwezibalo zemarike yehlabathi ngo-2011, izakhiwo ezenziwe ngamaplanga aseMntla Melika kunye nezixhobo zawo ezihambelanayo zithathe i-70% yesabelo semarike yezakhiwo zamaplanga zehlabathi.Phambi koo-1980, uboya belitye kunye noboya beglasi bakhethwa ukuba bugqume izakhiwo zesakhiwo somthi saseMelika, kodwa ke zafunyaniswa zineCarcinogen embi kwimpilo yabantu kunye nokusebenza ngokungasebenziyo kokugquma.Ngeminyaka yee-1990, i-American Wood Structure Association yacebisa ukuba zonke izakhiwo zezakhiwo zokhuni ziya kusebenzisa i-foam ye-polyurethane ephantsi yoxinzelelo lobushushu.Inobushushu obubalaseleyo kunye nokusebenza kokufakwa kwesandi, ikhuselekile kwaye inobuhlobo ne-Eco.I-SWD low density polyurethane spray foam ephuhliswe yi-SWD Urethane., e-USA isetyenziswe ngendlela yogwebu lwamanzi agcweleyo, ayisayi kutshabalalisa i-ozonosphere, ingenabungozi kokusingqongileyo, iyonga amandla, isiphumo esihle sokugquma kunye nokukhuphisana kwexabiso.Iye yaba yimveliso ephambili kwisakhiwo somthi we-villa insulation kwimarike yaseMelika.
