I ka wā e pili ana i ka insulation, he mea nui i nā mea kūkulu hale a me nā mea nona ka hale ke hoʻomaopopo i nā ana like ʻole i hoʻohana ʻia e loiloi i kona pono. ʻO kēia mau ana, ʻo ka waiwai K, ka waiwai U, a me ka waiwai R nā mea i hoʻohana pinepine ʻia. Hōʻike kēia mau waiwai āpau i ka hana wela o nā huahana insulation, me ka insulation FEF (foam extruded polystyrene). E ʻimi kēia ʻatikala i ka pilina ma waena o kēia mau waiwai a pehea lākou e pili ai i nā huahana insulation FEF.
Waiwai K: ke ana hoʻokele wela
ʻO ke K-value, a i ʻole ka thermal conductivity, he ana ia o ka hiki o kahi mea ke hoʻokele i ka wela. ʻO kona anakahi ʻo Watts no ka mika-Kelvin (W/m·K). ʻO ka haʻahaʻa o ka K-value, ʻoi aku ka maikaʻi o ka insulation, akā ʻo ia hoʻi, ʻaʻole i hoʻokele pono ka mea i ka wela. No nā mea insulation FEF, he mea koʻikoʻi ka K-value no ka mea e pili pololei ana ia i ka hiki o ka mea ke kūʻē i ke kahe wela. ʻO ka maʻamau, he haʻahaʻa nā K-values o nā huahana insulation FEF, kahi e hoʻolilo ai iā lākou i mea kūpono loa i nā ʻano hana like ʻole, mai nā hale noho a i nā hale kalepa.
U-waiwai: Ka helu hoʻoili wela holoʻokoʻa
Hōʻike ka waiwai-U i ke koina hoʻoili wela holoʻokoʻa o kahi mea hale, e like me ka paia, ka hale a i ʻole ka papahele. Hōʻike ʻia ma Watts no ka mika kuea-Kelvin (W/m²·K) a noʻonoʻo ʻaʻole wale i ka mea insulation, akā i nā hopena o nā hakahaka ea, ka makū a me nā mea ʻē aʻe. ʻO ka haʻahaʻa o ka waiwai-U, ʻoi aku ka maikaʻi o ka insulation, no ka mea, ʻo ia hoʻi ka emi ʻana o ka wela i nalowale a loaʻa paha ma o ka mea hale. I ka loiloi ʻana i nā huahana insulation FEF, he mea nui ka waiwai-U no ka hoʻomaopopo ʻana pehea e hana ai i nā noi honua maoli, ʻoiai ke hui pū ʻia me nā mea hale ʻē aʻe.
Waiwai R: ke kū'ē'ē i ke kahe wela
Ana ke kumukūʻai R i ke kūpaʻa wela o kahi mea, e hōʻike ana i kona kūpaʻa ʻana i ke kahe wela. ʻO kona mau anakahi he mika huinaha-Kelvin no ka watt (m²·K/W). ʻO ke kiʻekiʻe o ka waiwai R, ʻoi aku ka maikaʻi o ka insulation, ʻo ia hoʻi, ʻoi aku ka maikaʻi o ka pale ʻana o ka mea i ka hoʻoili wela. ʻOi aku ka kiʻekiʻe o nā waiwai R o nā huahana insulation FEF, e kūpono ana no ke kūkulu ʻana me ka mālama pono i ka ikehu. He mea nui loa ka waiwai R no nā mea nona ka hale e ʻimi nei e hōʻemi i nā kumukūʻai ikehu a hoʻonui i ka ʻoluʻolu o ko lākou mau wahi noho.
Ka pilina ma waena o ka waiwai K, ka waiwai U a me ka waiwai R i ka insulation FEF
He mea koʻikoʻi ka hoʻomaopopo ʻana i ka pilina ma waena o ka waiwai-K, ka waiwai-U a me ka waiwai-R no ka loiloi ʻana i ka hana o nā huahana insulation FEF. Nānā ka waiwai-K i ka mea ponoʻī, ana ka waiwai-R i kona kūpaʻa, a hāʻawi ka waiwai-U i kahi kiʻi ākea o ka hana holoʻokoʻa o kahi element hale.
No ka hoʻopili ʻana i kēia mau waiwai ma ke ʻano makemakika, hiki ke hoʻohana ʻia ke ʻano hana penei:
- **R-value = 1 / K-value**: Ke ʻōlelo nei kēia kaulike i ka emi ʻana o ka K-value (e hōʻike ana i ka conductivity thermal maikaʻi aʻe), piʻi ka R-value, ʻo ia hoʻi ka hoʻomaikaʻi ʻana i ka hana insulation.
- **Waiwai U = 1 / (waiwai R + nā mea pale ʻē aʻe)**: Hōʻike kēia haʻilula ʻaʻole i hoʻopilikia wale ʻia ka waiwai U e ka waiwai R o ka papa insulation, akā, e nā kumu ʻē aʻe e like me nā hakahaka ea a me nā alahaka thermal.
No nā huahana insulation FEF, ʻo nā waiwai K haʻahaʻa e hāʻawi i nā waiwai R kiʻekiʻe, kahi e kōkua ai i ka hoʻokō ʻana i nā waiwai U haʻahaʻa i ka wā e hoʻohui ʻia ai i nā ʻākoakoa hale. ʻO kēia hopena synergistic e hoʻolilo ai i ka insulation FEF i koho kaulana no nā mea kālai hale a me nā mea kūkulu hale e ʻimi nei i nā hoʻolālā mālama ikehu.
I ka hōʻuluʻulu manaʻo, ʻo ka waiwai-K, ka waiwai-U a me ka waiwai-R he mau hōʻailona pili like e hāʻawi ana i nā ʻike waiwai nui i ka hana wela o nā huahana insulation FEF. Ma ka hoʻomaopopo ʻana i kēia mau pilina, hiki i nā mea kūkulu hale a me nā mea nona ka hale ke hana i nā hoʻoholo naʻauao e pili ana i nā mea insulation, a laila e hana i nā wahi noho ʻoi aku ka maikaʻi o ka ikehu a me ka ʻoluʻolu. I ka hoʻomau ʻana o ka pono o ka ikehu i mea nui loa i ka ʻoihana kūkulu hale, e hoʻonui wale ʻia ke koʻikoʻi o kēia mau waiwai, no laila pono e noʻonoʻo ʻia i ke koho ʻana i nā hopena insulation.
