Ha abụọOgwe PIRnaoyi nchekwa panelsna-ezo aka na ihe mkpuchi dị elu. Isi ihe dị iche dị na ihe na arụmọrụ: PIR panels (polyisocyanurate panels) bụ nkwalite ka elu nke polyurethane (PUR), nwere ezigbo mgbochi ire ọkụ, iguzogide okpomọkụ dị elu (ruo 200℃ na karịa), na obere nnabata mmiri (dị ala karịa PUR). Ha bụ nhọrọ mbụ maka iwu ụlọ nchekwa oyi dị elu, ụlọ ọrụ nhazi nri, na ụlọ ndị ọzọ. "Panels nchekwa oyi" na-ezo aka na ihe mkpuchi eji eme ihe na nchekwa oyi, nke nwere ike ịbụ PIR, PUR, XPS, wdg. N'ihi arụmọrụ ya zuru oke, PIR aghọwo isi ihe dị mkpa nke ọgbara ọhụrụ dị eluogwe nchekwa oyi.
Njirimara Isi nke PIR (Polyisocyanurate) nke bọọdụ:

Mkpuchi Okpomọkụ Kachasị Elu: Oke ike nke okpomọkụ (≤0.023 W/mK), nke na-eme ka ọ dị mma maka mkpuchi.
Nguzogide Okpomọkụ Dị Elu: Ojiji ogologo oge nwere ike iguzogide okpomọkụ karịrị 150℃, ọbụna ruo 205℃, dabara adaba maka gburugburu okpomọkụ dị elu.
Mmiri Dị Ala: Ọ na-ebelata oke mmiri ịmịkọrọ, na-egbochi mmiri ịbanye nke ọma ma na-eme ka ọrụ mkpuchi dị mma.
Ike Dị Elu: Njupụta dị elu, nhazi kwụsiri ike, na-eme ka ike ụlọ dịkwuo mma.
Ezigbo Nchekwa Gburugburu Ebe Obibi: Enweghị CFC.
Ogwe Nchekwa Oyi:

PIR Panels vs. PUR Nkịtị Nchekwa Oyi Panels
Nguzogide Ọkụ: PIR > PUR
Nguzogide Okpomọkụ: PIR (-196℃ + 205℃) > PUR (-185℃ + 110℃)
Mmiri: PIR (<1%)< PUR (2.5% ~ 3%)
Njupụta: PIR (40-45 kg/m³) > PUR (38-40 kg/m³)
Ọnụ ego: PIR na-adịkarị elu karịa PUR.
