Hoʻāʻo ʻia ka vapor permeability o nā membrane roofing e nā ʻano ʻano like ʻole ma lalo o kekahi mau kūlana lab e like me ka mahana, ke kaomi a me ka haʻahaʻa o ka ea. He paʻakikī ka loaʻa ʻana o nā kūlana like i loko o ia mau haʻawina, no laila ʻaʻole hilinaʻi piha nā waiwai i hāʻawi ʻia ma kēia ala. Hāʻawi pinepine ʻia ka vapor permeability i nā ʻāpana o g/m2/lā, ʻo ia hoʻi ka nui o ka mahu wai i loko o nā grams e hele i loko o kahi mika square o ka pepa i kēlā me kēia lā. ʻO kahi hōʻailona pololei loa o ka mahu permeability o ka foil, ʻo ia ka diffusion resistance coefficient Sd, i hōʻike ʻia ma nā mika (e hōʻike ana i ka mānoanoa like me ka diffusion o ka ea). Inā ʻo Sd = 0,02 m, ʻo ia hoʻi, hana ka mea i ke kūʻē ʻana i ka mahu wai i hana ʻia e kahi ʻāpana 2 knm mānoanoa o ka ea. Hiki i ka mahu? ʻo kēia ka nui o ka mahu wai e hiki ai i ke kiʻi ʻoniʻoni (fleece, membrane) ke hele ma lalo o kekahi mau kūlana. He kiʻekiʻe anei kēia mahu wai e halihali ana i kekahi ala (nogligible kekahi)? No laila, he mea nui e kau i ka pepa ma luna o ka hale me ka ʻaoʻao ʻākau, i ka manawa pinepine me nā palapala i luna, i hiki ke komo i ka mahu wai mai loko a i waho. Ua kapa ʻia ke kiʻi ʻoniʻoni i lalo ma lalo o ke kiʻi ʻoniʻoni no ka mea hiki iā ia ke hoʻololi i ka uhi paʻa pepa kuʻuna. Hoʻolālā ʻia lākou e pale i ke ʻano o ka hale a me ka papa insulating mai ka ua a me ka hau e hāʻule ana ma lalo o ka uhi. Ua manaʻo ʻia ʻaʻole e puhi ʻia ka wela mai ka ʻaoʻao insulation thermal, no laila pono e pale aku i ka makani. A hope loa? ʻo ia ka wehe ʻana i ka wai nui i hiki ke komo i nā papa o ka hale mai loko o ka hale (i kēia hihia, pono ʻoe e hoʻomau i ka manaʻo e komo ka mahu wai i loko o kēia mau papa ma muli o nā leaka like ʻole). ʻO ka hana hope loa o ka foil? kona hikiwawe? ʻike ʻia ʻo ia ka mea koʻikoʻi koʻikoʻi i ke koho ʻana i ke ʻano o ke kiʻi ʻoniʻoni mai kahi ākea o nā mea hana. Manaʻo ʻia ke kiʻiʻoniʻoni e paʻa loa ka mahu ke Sd <0,04 m (e like me ka ʻoi aku ma mua o 1000 g/m2/24h ma 23°C a me 85% haʻahaʻa pili). ʻOi aku ka liʻiliʻi o ka coefficient Sd, ʻoi aku ka nui o ka permeability o ka mahu o ke kiʻiʻoniʻoni. Wahi a ka vapor permeability, ʻike ʻia nā pūʻulu o nā kiʻiʻoniʻoni me ka haʻahaʻa, waena a me ke kiʻekiʻe. emi iho ma mua o 100 g/m2/24 h? haʻahaʻa mahu permeable, a hiki i 1000 g / m2 / 24h - medium vapor permeable; ʻO ka coefficient Sd he 2-4 m; i ka wā e hoʻohana ai iā lākou, pono e mālama i kahi ākea ventilation o 3-4 cm ma luna o ka insulation e pale ai i ke komo ʻana o ka wai. Hiki ke waiho pololei ʻia nā kiʻiʻoniʻoni me ka nui o ka mahu ma luna o nā lāʻau a hui pū me ka papa insulating. ʻO ke kaumaha a me ke kū'ēʻana o nā membrane o ka hale i ka radiation ultraviolet e pili ana i ka lōʻihi o ka mea. ʻOi aku ka mānoanoa o ka pepa, ʻoi aku ka kūpaʻa ʻana i ka pōʻino mechanical a me nā hopena pōʻino o ka pāhawewe lā (me ka ultraviolet? UV). ʻO nā kiʻiʻoniʻoni maʻamau i hoʻohana ʻia he 100, 115 g/m2 ma muli o ka ratio maikaʻi loa o ke kaumaha i ka ikaika mechanical a me ka permeability vapor. ʻO nā kiʻiʻoniʻoni me ka hikiwawe kiʻekiʻe ke kūpaʻa i nā kukui UV no 3-5 mau mahina (me ka haʻahaʻa haʻahaʻa permeability 3-4 pule). Loaʻa ʻia kēlā ʻano kūʻē nui ma muli o nā stabilizers - additives i ka mea. Hoʻohui ʻia lākou no ka pale ʻana i nā kiʻiʻoniʻoni mai nā kukuna e komo i loko o nā āpau (a i ʻole nā lua) i ka uhi i ka wā o ka hana. ʻO nā mea hoʻohui e hoʻolohi i nā hopena pōʻino o ka hoʻoheheʻe ʻana o ka lā e hāʻawi i nā makahiki he nui o ka hoʻohana ʻana i ka mea, a ʻaʻole e koi i nā mea hana ʻaelike e mālama i ke kiʻiʻoniʻoni o ka hale ma ke ʻano he kaupaku no kekahi mau mahina. ʻO ke ana o ke kūpaʻa wai o ka foil ka pale ʻana o ka mea i ke kaomi o ke kolamu wai. Pono ia ma ka liʻiliʻi loa 1500 mm H20 (e like me ka German standard DIN 20811; ma Polani, ʻaʻole i hoʻāʻo ʻia ke kūpaʻa wai e like me kekahi maʻamau) a me 4500 mm H20 (e like me ka mea i kapa ʻia. kinetic method). Ua hana ʻia nā mea ʻālohilohi ma mua o ka uhi ʻana i ka plastic? i hana ʻia me ka polyethylene (paʻakikī a palupalu), polypropylene, polyester a me ka polyurethane, no laila ua ikaika lākou a kū i ka deformation. Hoʻohana pinepine ʻia nā kiʻi ʻoniʻoni ʻekolu-layer i hoʻopaʻa ʻia, aia kahi papa hoʻoikaika o ka mesh i hana ʻia me ka polyethylene paʻa, polypropylene a i ʻole fiberglass ma waena o polyethylene. Mahalo i kēia hoʻolālā, ʻaʻole lākou e pili i ka deformation i ka wā o ka hana a ma muli o ka ʻelemakule o ka mea. ʻO nā kiʻiʻoniʻoni me kahi papa anti-condensation he viscose-cellulose fiber ma waena o ʻelua papa polyethylene, kahi e hoʻomoʻa ai i ka mahu wai a hoʻokuʻu mālie. He haʻahaʻa loa ko nā kiʻiʻoniʻoni hope loa. Loaʻa i nā membrane hale (nā mea ʻaʻole i ulana ʻia) he ʻano papa. ʻO ka papa nui he polypropylene non-woven i uhi ʻia me ka polyethylene a i ʻole ka microporous polypropylene membrane, i kekahi manawa e hoʻoikaika ʻia me ka polyethylene mesh.
