Cov thev naus laus zis tseem ceeb ntawm hluav taws kub-cov khoom tiv thaiv rov qab yog nyob hauv lawv cov khoom siv. Feem ntau hluav taws kub-cov ntaub ntawv tiv thaiv cov ntaub ntawv vaj huam sib luag muaj xws li cov khoom siv tsis muaj organic-cov khoom siv hlau xws li aluminosilicate fiber, iav fiber, thiab ceramic fiber. Cov ntaub ntawv no muaj cov ntsiab lus melting siab heev (feem ntau tshaj 1000 degree) thiab thermal conductivity tsawg, ua rau lawv muaj kev ruaj ntseg ntawm cov qauv hauv siab - qhov kub thiab txias thiab tsis tsim cov pa phem. Noj aluminosilicate fiberboard ua piv txwv, nws yog tsim los ntawm aluminosilicate fibers los ntawm cov txheej txheem tshwj xeeb, tsim ntau qhov me me ntawm cov fibers. Cov pores no tsis tsuas yog txo cov khoom siv thermal conductivity tab sis kuj txhim kho nws lub suab nqus thiab txo cov suab nrov.
Hluav taws kub-cov vaj huam sib luag tiv thaiv yog tsim tshwj xeeb los txhim kho hluav taws kub ntawm cov tsev lossis khoom siv. Lawv lub luag haujlwm tseem ceeb yog kom txo qis kev sib kis ntawm hluav taws thaum muaj hluav taws, yuav lub sijhawm muaj txiaj ntsig rau kev khiav tawm thiab kev tua hluav taws. Cov vaj huam sib luag no feem ntau yog ua los ntawm cov uas tsis yog -combustible los yog nplaim taws- cov ntaub ntawv retardant, muaj cov hluav taws kub zoo heev thiab thermal stability, zoo tiv thaiv kev sib kis ntawm nplaim taws thiab kub kub.
