Enwere ike nweta mmetụta mkpuchi mkpuchi ka mma site na HFC, ọkachasị na njupụta nnukwu dị ala. Eserese a na-egosi na ihe mkpuchi mkpuchi HFC nwere nnukwu njupụta nke 15 kg/m³ dịka ọmụmaatụ na-enweta nrụpụta ọkụ nke 0.032 W/(m·K). Na EPS nkịtị nwere otu nnukwu njupụta, conductivity thermal bụ 0.037 W / (m·K).
