I ka wā e pili ana i ka insulation, he mea nui ia no ka poʻe kūkulu hale a me nā mea hale e hoʻomaopopo i nā ana like ʻole i hoʻohana ʻia e loiloi i kona pono. ʻO kēia mau ana, ʻo K-waiwai, U-waiwai, a me R-waiwai ka mea maʻamau i hoʻohana ʻia. Hōʻike kēia mau waiwai i ka hana wela o nā huahana insulation, me ka FEF (foam extruded polystyrene) insulation. E ʻimi kēia ʻatikala i ka pilina ma waena o kēia mau waiwai a pehea e pili ai i nā huahana insulation FEF.
K waiwai: koena hoʻopalekana wela
ʻO ka waiwai K, a i ʻole ka hoʻoili wela, he ana ia o ka hiki o kahi mea ke lawe i ka wela. ʻO kāna ʻāpana Watts no ka mika-Kelvin (W/m·K). ʻO ka haʻahaʻa o ka K-waiwai, ʻoi aku ka maikaʻi o ka insulation, akā ʻo ia ke ʻano o ka lawe ʻana i ka wela me ka liʻiliʻi. No ka FEF mea insulation, he mea koʻikoʻi ka K-value no ka mea pili pono i ka hiki o ka mea ke pale i ka kahe wela. ʻO ka mea maʻamau, ʻo nā huahana insulation FEF he mau K-waiwai haʻahaʻa, kahi e hoʻoikaika nui ai lākou i nā ʻano noi like ʻole, mai nā hale noho a i nā hale kalepa.
U-waiwai: Ka huina hoonui wela
Hōʻike ka U-waiwai i ka huina hoʻololi wela o kahi mea hale, e like me ka pā, ka hale a i ʻole ka papahele. Hōʻike ʻia ia ma Watts per square meter-Kelvin (W/m²·K) a noʻonoʻo ʻaʻole wale i nā mea insulation wale nō, akā i nā hopena o nā āpau o ka ea, ka haʻahaʻa a me nā mea ʻē aʻe. ʻO ka haʻahaʻa o ka U-waiwai, ʻoi aku ka maikaʻi o ka insulation, no ka mea, ʻoi aku ka liʻiliʻi o ka wela i nalowale a loaʻa paha ma o ka mea hale. I ka loiloi ʻana i nā huahana insulation FEF, pono ka U-value e hoʻomaopopo i ke ʻano o ka hana ʻana i nā noi honua maoli, ʻoi aku ka nui o ka hui ʻana me nā mea kūkulu hale ʻē aʻe.
R waiwai: kū'ē i ke kahe wela
ʻIke ʻia ka waiwai-R i ke kūpaʻa wela o kahi mea, e hōʻike ana i kona pale ʻana i ka kahe wela. ʻO kāna mau ʻāpana he mika square-Kelvin no ka watt (m²·K/W). ʻO ke kiʻekiʻe o ka R-waiwai, ʻoi aku ka maikaʻi o ka insulation, ʻo ia hoʻi ka ʻoi aku ka maikaʻi o ka hoʻololi ʻana i ka wela. ʻO nā huahana insulation FEF ka mea maʻamau i nā waiwai R kiʻekiʻe, e hoʻolilo iā lākou i mea kūpono no ke kūkulu ʻana i ka ikehu. He mea koʻikoʻi ka R-value no nā mea hale e ʻimi nei e hōʻemi i nā kumukūʻai ikehu a hoʻonui i ka hōʻoluʻolu o ko lākou mau wahi noho.
ʻO ka pilina ma waena o ka waiwai K, ka waiwai U a me ka waiwai R i ka insulation FEF
ʻO ka hoʻomaopopo ʻana i ka pilina ma waena o K-value, U-value a me R-value he mea koʻikoʻi i ka loiloi ʻana i ka hana o nā huahana insulation FEF. Hoʻopili ka waiwai K i ka waiwai ponoʻī, ana ka waiwai R i kona kūʻē, a hāʻawi ka U-waiwai i kahi kiʻi ākea o ka hana holoʻokoʻa o kahi mea hale.
No ka hoʻopili makemakika i kēia mau waiwai, hiki ke hoʻohana ʻia kēia ʻano kumu:
- **R-waiwai = 1 / K-waiwai**: Hōʻike kēia haʻihaʻi i ka emi ʻana o ka waiwai K (e hōʻike ana i ka ʻoi aku ka maikaʻi o ka hoʻokele wela), piʻi ka R-waiwai, ʻo ia ka hoʻomaikaʻi ʻana i ka hana insulation.
- **U waiwai = 1 / (R waiwai + nā mea kū'ē'ē aʻe)**: Hōʻike kēia ʻano hoʻohālikelike ʻaʻole i hoʻopili wale ʻia ka waiwai U e ka waiwai R o ka papa insulation, akā e nā mea ʻē aʻe e like me nā ea a me nā alahaka wela.
No nā huahana insulation FEF, hāʻawi nā K-waiwai haʻahaʻa i nā waiwai R kiʻekiʻe, ʻo ia hoʻi ke kōkua i ka hoʻokō ʻana i nā waiwai U haʻahaʻa i ka wā i hoʻohui ʻia i nā hale kūkulu hale. ʻO kēia hopena synergistic e hoʻolilo i ka insulation FEF i koho kaulana no nā mea kākau a me nā mea kūkulu hale e ʻimi nei i nā hoʻolālā ʻoi aku ka ikaika.
I ka hōʻuluʻulu ʻana, ʻo K-value, U-value a me R-value he mau hōʻailona pili e hāʻawi i nā ʻike waiwai 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 hale ke hana i nā hoʻoholo ʻike e pili ana i nā mea insulation, i ka hopena o ka hana ʻana i nā wahi noho ʻoi aku ka ikaika a me ka ʻoluʻolu. Ke hoʻomau nei ka ikaika o ka ikehu i mea nui i ka ʻoihana kūkulu, e hoʻonui wale ka nui o kēia mau waiwai, no laila pono lākou e noʻonoʻo i ke koho ʻana i nā hopena insulation.
