Amabhodi e-PIR, amafushane ngamabhodi egwebu e-polyisocyanurate, ayimpahla yokwaleka ethuthukisiwe nethuthukisiwe esekelwe ku-polyurethane (PU). Ngokulungisa isilinganiso se-isocyanate kuma-polyols kanye nokwengeza izinqamuleli ze-flame ezisebenza kahle kakhulu, kwakheka isakhiwo sendandatho ye-triazine ezinzile, sithuthukise kakhulu ukumelana nokushisa kanye ne-flame retadancy{1}}ngokujwayelekile ifinyelele ku-B1 flame-izinga elibambekayo,{4}}ukuzicisha{4}}ukuzicisha lapho kususwa ukushunqa, kanye nezinga lokushisa eliphansi, kanye nezinga eliphezulu lokushisa. Uma kuqhathaniswa namabhodi e-polystyrene endabuko e-XPS akhishwe, i-PIR ine-thermal conductivity ephansi (imvamisa Ingaphansi noma ilingana no-0.022W/(m·K)) ekushubeni okufanayo, ukusebenza kahle kokufakwa kwe-insulation, futhi ifaneleka kakhulu izimo ezinezidingo eziqinile zakho kokubili ukumelana nomlilo nokusebenza kahle kwamandla.
Lapho ngikhetha ukufakwa kwesistimu yokushisa engaphansi kwendlu yami, ngiqhathanise izinketho ezimbalwa futhi ekugcineni ngakhetha leli bhodi le-PIR eliluhlaza okwesibhakabhaka. Ngemva kokuyibeka, yazizwa iqinile futhi ayizange idilike ngaphansi kwezinyawo, ukusikeka kwakuhlanzekile futhi kungawohloki, futhi yayibambelele ngokuqinile ezindongeni, emapayipini okushisa angaphansi, ngisho nanjengesisekelo sokugcina abandayo. Okuqinisekisa kakhulu ukuthi i-blue hue ayidayi; kuwuphawu olwakhiwe ukuhlakazeka ngokulinganayo kwe-flame retardant. Uma kushiswa ikhoneni elincane, likhipha intuthu emhlophe kuphela futhi liyeke ukuvutha ngokushesha nje lapho intuthu igoqa. Uma isetshenziswa ku-insulation yangaphakathi yezindonga zangaphandle zesakhiwo esidala, ivimbela ukuminyana emafasiteleni ebusika futhi igwema ukugcwala esitezi esiphezulu ehlobo. Ngemva kokufakwa endaweni encane yokugcina abandayo yezokwelapha, ukushintsha kwezinga lokushisa kuncipha kakhulu, futhi i-compressor iqala futhi ime kancane kancane.
