PIR mapuranga, mapfupi e polyisocyanurate foam board, ari akagadziridzwa uye akakwidziridzwa ekudzivirira zvinhu anobva pa polyurethane (PU). Nekugadzirisa reshiyo yeisocyanate kune polyols uye nekuwedzera zvinodzora moto zvinonyanya kushanda, chimiro chemhete chetriazine chinogadzirwa, chinonatsiridza kusapisa uye kunonoka kwemurazvo{1}}kazhinji kusvika paB1 murazvo{3}}usingadzoreki, unodzima{4}}pakubvisa kunyura, nekudzika kwehutsi, nekudzika kwehutsi. Zvichienzaniswa neyekare XPS extruded polystyrene boards, PIR ine yakaderera thermal conductivity (kazhinji Isingasviki kana kuenzana ne0.022W/(m·K)) pahukobvu hwakafanana, kukwirira kwekudzivirira kwesimba, uye inonyatso kuenderana nemamiriro ezvinhu ane stringent zvinodiwa kune zvese kudzivirira moto uye kushanda nesimba.
Pakusarudza insulation yeimba yangu yepasi yekudziya system, ndakafananidza akati wandei sarudzo uye pakupedzisira ndakasarudza iyi yebhuruu PIR board. Mushure mekuradzika, yainzwa yakasimba uye isingadonhe pasi, kucheka kwaive kwakachena uye kusaputsika, uye yakaramba yakatsiga kumadziro, pombi dzekudziya dzepasi, uye kunyange sepasi pekuchengetera chando. Chinonyanya kunyaradza ndechekuti ruvara rwebhuruu haruna dhayi; mucherechedzo unoumbwa nekupararira kwemoto unodzoreredza moto. Kana kakona kadiki kakatsva, kanongoburitsa chiutsi chichena chomira kutsva kana chiutsi chapeta. Kana ichishandiswa mukati mekudzivirira kwechivakwa chekare madziro ekunze, inodzivirira kutenderera kwakatenderedza mahwindo munguva yechando uye inodzivirira stuffiness pauriri hwepamusoro muzhizha. Mushure mekuiswa mune diki yekurapa inotonhora yekuchengetera compartment, tembiricha inodzikira zvakanyanya kuderedzwa, uye compressor inotanga uye inomira zvakanyanya zvinyoro.
