Qhov ntom ntawm iav wool board yog qhov taw qhia tseem ceeb ntawm nws cov kev ua tau zoo thiab cov ntawv thov; Feem ntau ntsuas hauv kg / m³, qhov sib txawv ntawm qhov sib txawv raws li kev siv tshwj xeeb thiab kev ua haujlwm tseem ceeb.
Feem ntau, qhov ceev ntawm cov iav ntaub plaub yog li ntawm 10 txog 100 kg / m³. Tsawg- cov khoom siv ntom ntom (kwv yees . 10–30 kg/m³) muaj cov qauv xoob nrog cov huab cua siab, ua rau lawv zoo tagnrho rau kev nqus suab thiab txo suab nrov- xws li hauv qab nthab, phab ntsa hauv ob sab phlu, thiab acoustic optimization. Thaum muaj txiaj ntsig zoo ntawm kev nqus nruab nrab - mus rau - lub suab nrov nrov, cov khoom siv no muaj lub zog qis qis.
Nruab nrab- cov rooj tsav xwm ceev (kwv yees. 30–60 kg/m³) cuam tshuam qhov sib npaug ntawm cov rwb thaiv tsev thermal thiab lub suab nqus, ua rau lawv muaj ntau yam kev xaiv. Lawv feem ntau yog siv rau kev tsim vaj tse sab nrauv phab ntsa, vov tsev, thiab cov khoom siv dav dav lossis cov kav dej thaiv, vim lawv ua tau raws li lub zog- cov qauv kev ua tau zoo thaum tuav cov qauv kev ruaj ntseg.
High- iav ntaub plaub boards (kwv yees . 60–100 kg / m³ lossis siab dua) feem ntau yog siv rau cov rwb thaiv tsev los yog hauv cov chaw ua haujlwm uas xav tau lub zog ntau dua- xws li rau cov khoom loj - cov khoom siv nplai, cov pa cua cladding, los yog cov cheeb tsam raug rau cov khoom siv sab nraud. Cov khoom no muaj cov qauv denser nrog superior compressive thiab cua -tsis kam muaj peev xwm, txawm hais tias lawv lub suab- kev nqus tau qis dua.
Yog li ntawd, xaiv qhov tsim nyog ntom rau ib qhov project yuav tsum muaj kev ntsuam xyuas zoo ntawm thermal rwb thaiv tsev, lub suab nqus, thiab lub zog ntawm cov qauv, es tsis yog xaiv qhov siab los yog tsawg.
