Vapor barrier ru tsev - ib tug yuav tsum tivthaiv ntawm niaj hnub siv

Lub yees tshaj tawm hais tias kev siv ntawm niaj hnub cov ntaub ntawv, uas coj mus rau lub Modernization ntawm lub ru tsev system. Pitched ru tsev - ib tug ntau-nyuab tsim rau ib tug yooj yim huab cua tiv thaiv, txuag lub feem ntau xis kub, kawm tuab si lug kub thiab humidity theem nyob rau hauv tshem tawm haus luam yeeb. Zoo zog ru tsev yuav tsuas yuav tau nrog rau cov kev siv uas niaj hnub cov ntaub ntawv. Yuav ua li cas yog cov hydraulic thiab vapor barrier ntaub ntawv? Ua ntej ntawm tag nrho lawv yog tsim nyog los tiv thaiv termosloja los ntawm absorbing dej. Feem ntau, raws li ib tug rhaub yog siv pob zeb los yog pob zeb hauv av wool. Nws yuav tsum tau muab sau tseg tias cov ntaub ntawv uas nkag adsorbs dej muaj nyob rau hauv cov huab cua, thiab qhov no undesired point, vim hais tias nws loses nws cov cim zog (piv txwv li, humidification khoom yog 5 feem pua muab lub tshav kub tsis mus rau 50%). Tsis tag li ntawd qhov no kub sib txawv muaj txhawb mus rau tsim ntawm condensate, uas exhibits ib tug tsis zoo feem nyob rau rwb thaiv tsev thiab hlau. Hydro, chav yuav tiv thaiv tau cov tsim ntawm condensate, yuav tiv thaiv cov rwb thaiv tsev ntawm lub phiv los ntawm dej rau nws. Conventionally, lub saum toj no cov ntaub ntawv muaj peev xwm yuav txwv kom muab zais rau hauv lub nram qab no: anti-hws zaj duab xis (flashing) thiab diffuse membrane.

Anti-hws zaj duab xis siv rau ntxiv tiv thaiv los ntawm nag dej ntws mus rau hauv lub cua inputs, ru tsev txia, etc. Tswvcuab khoom mounted nyob rau hauv lub ru tsev yuav tsum vov ru tsev. Diffuse daim nyias nyias - ib tug tshwj xeeb cov ntaub ntawv uas muaj lub peev xwm tsim dej vapor generated nyob rau hauv lub chaw thiab nyob rau hauv lub ru tsev ntawm lub nce vim convection dab. Lub week yuav tsum tau ntsia ntawm lub sab hauv sab ntawm lub rwb thaiv tsev ntaub. Lub zaj duab xis combines diffuse thiab tawm tsam hws zog. Nyob rau hauv lawv muaj pes tsawg leeg kuj muaj xws li ib tug ntxeem tau dej txheej, sau condensed dej, thiab tom qab nws zoo suab.

Vapor barrier ru tsev nyob rau tej kev qhia raws li cov pa dej permeability, piv txwv li lub membrane yog ib tug uas muaj txhawb rau cov dawb tawm ntawm chav los ntawm lub tsev. Anticondensation membrane - ib tug indispensable khoom nyob rau hauv lub installation thiab kev kho ntawm attics. Kom installation ntawm waterproofing zaj duab xis muab zoo cua rwb thaiv tsev txheej. Lub npe yog stacked nyob rau hauv sab saum toj ntawm lub rhaub, li ntawd, nyob rau hauv cov ntaub ntawv no, txiav tshem qhov yuav tsum tau rau tsim ntawm ib tug thiaj li hu ua cua kis. Nrog rau kev siv ntawm vapor barrier week ua tau embedment ntawm rwb thaiv tsev yuav tsum tau thickness, uas sib raug mus rau lub thickness ntawm cov rafters lawv tus kheej.

Vapor ru tsev tau siv niaj hnub chav thiab waterproofing cov ntaub ntawv, uas yog ua nyob rau hauv daim ntawv ntawm qaws ntawm zaj duab xis, uas muaj nuj nqis simplifies stacking txheej txheem, enables ib tug nruj kev foob nrog cov npoo ntawm cov pob qij nws thiaj li tus naj npawb ntawm ntug txaj. Cov ntaub ntawv no yog siv nyob rau hauv lub installation ntawm tej vov tsev systems los ntawm tej hub rau puas. Raws li ib tug tshwm sim, ib tug vapor barrier ntawm lub-ru tsev yuav ua kom cov kev tiv thaiv ntawm lub ru tsev cov ntaub ntawv uas, yuav los txhim kho lub rwb thaiv tsev thiab cuag cov ua hauj lwm zoo tsim lub neej. Tshwj xeeb yog nrov chav thiab waterproofing ntaub ntawv nram qab no hom: Durco, Monarfleks, Klauber, Tyvek. Vapor barrier ntawm lub-ru tsev yuav ua tau nrog kev pab los ntawm lwm insulating cov ntaub ntawv, cov kev xaiv ntawm lub lag luam yog heev loj, yog li ntawd koj yuav tau yooj yim yuav tsum khaws cov ntaub ntawv nrog rau cov kev kawm loj ntawm ib tug vapor-permeable - xam nyob rau hauv qhov kev mob ntawm tus neeg los yog lwm yam chaw.
