Cov ntaub ntawv rwb thaiv tsev cua sov thiab cov khoom lag luam yog qhov tseem ceeb cuam tshuam rau kev tsim txuag hluav taws xob. Kev tsim kho thiab siv ntawm cov cuab yeej ua haujlwm thaiv tsev thermal tau them ntau dua thiab ntau dua los ntawm cov teb chaws thoob ntiaj teb. Tom qab xyoo 1970, txawv teb chaws feem ntau them sai sai rau kev tsim khoom thiab kev siv cov khoom siv rwb thaiv tsev thermal hauv kev tsim kho, thiab sib zog los txo kev siv hluav taws xob ntau, yog li txo qis kev ua qias tuaj thiab ua rau lub tsev ntsuab. Kev lag luam txawv teb chaws thermal hloov khoom lag luam muaj keeb kwm ntev. Thermal rwb thaiv tsev ntaub ntawv rau lub tsev kev txuag lub zog rau feem ntau, thiab cov khoom siv rwb thaiv tsev thermal tshiab tsis tu ncua.
Ua ntej xyoo 1980, kev txhim kho Tuam Tshoj' s cov khoom siv thermal rwb thaiv tsev tau qeeb heev, tab sis tom qab ntau tshaj 30 xyoo ntawm kev ua haujlwm nyuaj hauv Tuam Tshoj' s thermal rwb thaiv tsev cov ntaub ntawv kev lag luam, tshwj xeeb yog tom qab ze li 20 xyoo ntawm kev txhim kho sai, ntau yam cov khoom lag luam tau nce los ntawm tsis muaj dab tsi, los ntawm ib tus mus rau ntau haiv neeg, thiab lawv cov khoom tau zoo tau tsawg. Ntawm qhov chaw siab, ib qho kev lag luam tiav tau tsim, feem ntau suav nrog nthuav dav perlite, pob zeb hauv av tsiaj, iav ntaub plaub, ua npuas ua npuas yas, ua kom muaj cov kab ua haujlwm, thiab calcium silicate rwb thaiv cov khoom lag luam.
Txij Lub Ib Hlis Ntuj mus txog Lub Kaum Ob Hlis 2006, cov tsiaj hauv av; nthuav cov ntaub ntawv ntxhia; kub lossis suab rwb thaiv tsev ntaub cov khoom lag luam ntau npaum li cas rau 13,110,148.00 kg, nrog kev sib pauv txawv txawv 29,396,269.00 Asmeskas las; txij Lub Ib Hlis mus txog Lub Kaum Ob Hlis 2006, Tuam Tshoj xa tawm cov paj rwb ntxhia; nthuav cov ntaub ntawv ntxhia; kub lossis suab rwb thaiv tsev Qhov ntau ntawm cov khoom lag luam yog 323,873,323.00 kilo, thiab kev hloov pauv txawv teb chaws yog 141,929,418.00 Asmeskas las.
Txij Lub Ib Hlis Ntuj txog Lub Kaum Hlis 2007, cov tsiaj hauv av; nthuav cov ntaub ntawv ntxhia; tshav kub lossis suab rwb thaiv tsev ntaub cov khoom lag luam ntau npaum li cas ntawm 12,844,531.00 kg, nrog kev hloov pauv txawv teb chaws 28,133,066.00 Asmeskas las; txij Lub Ib Hlis Ntuj mus txog Lub Kaum Hlis 2007, Tuam Tshoj xa tawm pob zeb hauv av; nthuav cov ntaub ntawv ntxhia; tshav kub lossis suab rwb thaiv tsev Qhov ntau ntawm cov khoom lag luam yog 293,114,475.00 kg, thiab tus nqi pauv yog US $ 148,816,708.00.
Cov ntaub polyurethane yog cov khoom siv rwb thaiv tsev thermal thoob ntiaj teb nrog kev ua haujlwm zoo. Rigid polyurethane muaj ntau yam ntxwv zoo thiab yog siv dav hauv tsev, ru tsev, phab ntsa, nthab, plag tsev, qhov rooj thiab lub qhov rais hauv cov tebchaws European thiab Asmeskas yog cov khoom siv rwb thaiv tsev thermal. Kwv yees li 49% ntawm lub tsev cov khoom siv rwb thaiv tsev hauv cov tebchaws tsim kho xws li Tebchaws Europe thiab Tebchaws Asmeskas yog cov ntaub ntawv polyurethane, thaum nyob hauv Suav Tebchaws qhov feem pua no tseem tsawg dua 10%. Yog li ntawd, tseem muaj ntau chav rau kev txhim kho cov khoom lag luam polyurethane hauv Suav.
Kev lag luam kev txuag hluav taws xob hauv tsev ua nyob hauv Suav teb yog qhov loj me, tshwj xeeb tshaj yog kev tsim kho cov khoom siv rwb thaiv tsev. Lub zog poob ntawm cov tsev hauv Suav yog ze li 50% rau phab ntsa; 10% rau lub ru tsev; 25% rau qhov rooj thiab lub qhov rais; thiab 15% rau hauv qab daus thiab plag tsev. Yuav kom ua tiav qhov kev txuag hluav taws xob ntawm 50% hauv xyoo 2010, Suav cov tuam tsev yuav tsum kho lub tsev sab nrauv ntawm cov tsev, thiab kev ua lag luam rau cov txheej txheem thaiv phab ntsa yuav nce ntxiv
