ʻO nā papa PIR, pōkole no ka polyisocyanurate foam papa, he mea hoʻomaikaʻi a hoʻomaikaʻi ʻia hoʻi ka insulation ma muli o ka polyurethane (PU). Ma ka hoʻololi ʻana i ka ratio o ka isocyanate i polyols a me ka hoʻohui ʻana i nā mea pale ahi maikaʻi loa, ua hoʻokumu ʻia kahi ʻōnaehana apo triazine paʻa, e hoʻomaikaʻi maikaʻi loa i ka pale ʻana i ka wela a me ka hiki ʻana o ka lapalapa ahi -e maʻa mau i ka B1 lapalapa -maʻamau, ʻo ia iho-piʻi ʻana ma ka wehe ʻana o ka uahi haʻahaʻa, ʻaʻole me ka maʻalahi o ka uwahi. Hoʻohālikelike ʻia me nā papa polystyrene XPS extruded, PIR he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa (ʻoi aku ka liʻiliʻi ma mua o a i ʻole like me 0.022W/(m·K)) ma ka mānoanoa like, ʻoi aku ka maikaʻi o ka insulation, a ʻoi aku ka maikaʻi no nā hiʻohiʻona me nā koi koʻikoʻi no ke kūpaʻa ahi a me ka ikaika o ka ikehu.
Ke koho ʻana i ka insulation no ka ʻōnaehana hoʻomehana ma lalo o ka papahele o koʻu home, ua hoʻohālikelike au i kekahi mau koho a ua koho hope i kēia papa PIR polū. Ma hope o ka waiho ʻana, ua paʻa a ʻaʻole i hāʻule i lalo o ka wāwae, ua maʻemaʻe nā ʻoki a ʻaʻole i hina, a paʻa mau i nā paia, nā paipu hoʻomehana ma lalo o ka papahele, a me ke kumu no ka mālama anu. ʻO ka mea hōʻoluʻolu loa, ʻaʻole ia ka waihoʻoluʻu ʻulaʻula; he hōʻailona i hana ʻia e ka hoʻopuehu like ʻana o ka lapalapa ahi. Ke puhi ʻia kahi kihi liʻiliʻi, hoʻopuka wale ʻo ia i ka uahi keʻokeʻo a pau ke ahi i ka wā e wili ai ka uahi. Ke hoʻohana ʻia i loko o ka insulation o loko o ka hale kahiko o nā paia o waho, pale ia i ka condensation a puni nā puka makani i ka hoʻoilo a pale i ka stuffiness ma ka papahele o luna i ke kauwela. Ma hope o ka hoʻokomo ʻia ʻana i loko o kahi keʻena mālama anu olakino liʻiliʻi, hoʻemi nui ʻia ka loli ʻana o ka mahana, a hoʻomaka ka compressor a kū mālie.
