Ma board a PIR, omwe amafupikitsidwa ndi ma board a thovu a polyisocyanurate, ndi zida zokongoletsedwa bwino komanso zokwezeka zozikidwa pa polyurethane (PU). Posintha chiŵerengero cha isocyanate ndi ma polyols ndi kuwonjezera zoletsa moto zogwira mtima kwambiri, ring'i yokhazikika ya triazine imapangidwa, yomwe imathandiza kwambiri kuti isamatenthedwe ndi kutentha ndi kuchedwa kwa malawi{1}}kawirikawiri ikufika pamoto wa B1-wolephereka, wozimitsa{4}}wozimitsa{4}}pakuchotsa kutentha, komanso kutentha pang'ono, komanso kutentha pang'ono. Poyerekeza ndi matabwa amtundu wa XPS extruded polystyrene, PIR ili ndi kutsika kwa matenthedwe (nthawi zambiri Ochepera kapena ofanana ndi 0.022W/(m·K)) pa makulidwe omwewo, kutsekemera kwapamwamba kwambiri, ndipo ndi koyenera kwambiri pazochitika zomwe zimakhala ndi zofunikira zolimba pa zonse zomwe zimayaka moto komanso mphamvu zowonjezera mphamvu.
Posankha zosungunulira zotenthetsera zapansi pa nyumba yanga, ndidafanizira zosankha zingapo ndipo pamapeto pake ndinasankha bolodi ya buluu ya PIR. Atachiyika, chinkamveka cholimba ndipo sichinagwere pansi, mabala ake anali oyera komanso osasweka, ndipo ankakhala mokhazikika ku makoma, mapaipi otenthetsera pansi, komanso ngakhale ngati maziko osungiramo kuzizira. Chomwe chimatsimikizira kwambiri ndikuti mtundu wa buluu sukhala utoto; ndi chizindikiro chopangidwa ndi ngakhale kumwazikana kwa choletsa moto. Ngodya yaing’ono ikawotchedwa, imangotulutsa utsi woyera ndipo imasiya kuyaka utsiwo ukangopindika. Ikagwiritsidwa ntchito m'kati mwa makoma akunja a nyumba yakale, imalepheretsa kuti mazenera azitha kuzungulira mazenera m'nyengo yozizira komanso amapewa kuyika kwapamwamba pansi m'chilimwe. Pambuyo poyikidwa m'kachipinda kakang'ono kosungirako kuzizira kwachipatala, kusinthasintha kwa kutentha kumachepetsedwa kwambiri, ndipo kompresa imayamba ndikuyima mofatsa kwambiri.
