(1) Haʻahaʻa haʻahaʻa.ʻO 1/5 wale nō ia o ka pōhaku lepo māmā a me ka 1/10 o ka pōhaku lepo maʻamau, e hāʻawi ana i nā kūlana no ka māmā o ka umu ahi.

(2) Haʻahaʻa thermal conductivity.ʻO ka conductivity thermal ka waiwai koʻikoʻi o nā mea insulation thermal.Ke hoʻohālikelike ʻia me nā mea kaumaha a me ka māmā refractory, ʻo kona conductivity thermal ka haʻahaʻa loa

(3) Haʻahaʻa wela wela.ʻOi aku ka haʻahaʻa o ka mana wela o ka aluminosilicate refractory fiber ma mua o ka māmā maʻamau a me nā brick refractory kaumaha, no laila ua hoʻohana ʻia no ka uhi ʻana o ka umu wela, me ka piʻi wikiwiki a me ka hoʻohana wela.Hoʻohālikelike i ka mana mālama wela ma waena o ka alumini silicate refractory fiber a me nā mea kaumaha a māmā.

(4) Ke kū'ē kū'ē wela wela a me ke kū'ē mechanical.No ka mea ʻo ka alumini silicate refractory fiber he elastic a maʻalahi, ʻaʻole ia e ʻili ma lalo o nā kūlana anuanu a wela, a hiki ke pale aku i ke kulou ʻana, wili a me ka haʻalulu mechanical.Ma hope o ke kūkulu ʻia ʻana o ka uhi ahi, ʻaʻole pono e hoʻomaloʻo i ka umu, ʻaʻole i kaupalena ʻia e ka piʻi ʻana o ka mahana a hāʻule i ka wā o ka hoʻohana ʻana.

(5) Paʻa nā waiwai kemika.Ma waho aʻe o ka hoʻopili ʻia ʻana e ka waika hydrofluoric a me ka waika ikaika, ʻaʻole e ʻino ʻia ka fiber refractory, e like me ka mahu, ka aila a me nā waikawa a me nā alkali.

(6) ʻAʻole pulu i ka metala hoʻoheheʻe.ʻAʻole hoʻomaʻemaʻe ka alumini silicate refractory fiber i ka alumini, ke alakaʻi, ka tin, ke keleawe a me nā metala ʻē aʻe i loko o ka wai.
