Nā kūlana e hiki ai ke hoʻololi ʻia: Inā ʻino ka maikaʻi o ka papa extruded polystyrene (XPS) (e laʻa, hana ʻia e nā hale hana liʻiliʻi me ka hoʻohana ʻana i nā mea hana hou) a i ʻole i ʻike ʻia i nā mahana ma mua o 70 degere a me ka hoʻomau ʻana o ka lā, hiki ke hoʻopilikia ʻia kona paʻa ʻana. I kēia hihia, ʻoi aku ka nui o ka neʻe ʻana o nā molekala kūloko o ka mea ma muli o ke kiʻekiʻe o ka wela, e alakaʻi ana i ka hoʻonui a i ʻole ka hoʻopaʻa ʻana, i ka hopena i nā ʻano deformation e like me ka warping a me ka denting.
ʻO nā kūlana i hiki ʻole ke hoʻololi ʻia: -ʻano kiʻekiʻe nā papa XPS maikaʻi e kū ana i nā kūlana ʻāina ma ke ʻano he paʻa i loko o ka pae wela hana maʻamau (-50 degere a 70 degere). Me ke kōkua o nā hana pale e like me ka uhi ʻana me ka lole malu a i ʻole ke kau ʻana i nā ʻāpana hoʻokaʻawale wela, hiki ke hoʻemi pono ʻia nā hopena o ka lā pololei. ʻO kahi laʻana, ʻo ka hana maʻamau i nā kahua kūkulu ʻo ia ka uhi ʻana i nā waihona papa XPS me nā tarpaulins.
