Ndi chitukuko chosalekeza cha kumanga mphamvu yopulumutsa mphamvu, kuteteza kutentha ndi kutentha kwa kutentha kwa nyumba, monga gawo lofunika kwambiri la kumanga mphamvu yopulumutsa mphamvu, kwakhala gawo latsopano la kafukufuku waukadaulo wopulumutsa mphamvu ndikugwiritsa ntchito m'dziko lathu.

Ubweya wamchere makamaka umatanthawuza ubweya wa miyala, ubweya wa mchere, ubweya wagalasi, ubweya wa aluminium silicate ndi mankhwala awo.Ili ndi kachulukidwe kakang'ono, kutsika kwamafuta, kukhazikika kwamankhwala abwino komanso sikuwotcha, kukana kutentha, kukana chisanu, kukana dzimbiri, kukana tizilombo.Kuyambira m'zaka za m'ma 1950, ubweya wa mchere wakhala ukugwiritsidwa ntchito kwambiri popanga mafakitale.Tsopano imagwiritsidwa ntchito kwambiri mumitundu yosiyanasiyana ya nyumba, ndipo dongosolo lathunthu lazinthu lapangidwa.Magulu azinthu amaphatikizapo kumva, bolodi, chipolopolo cha chubu, chipika, mphasa, chingwe, bolodi ndi zina zotero.Ubweya wa Mineral ndiye chinthu chachikulu choteteza kutentha komanso kutulutsa mawu pamakampani ndi zomangamanga mdziko lathu.

Extruded polystyrene (XPS) ndi mtundu watsopano wazinthu zotchinjiriza zomwe zidapangidwa kunja kwa zaka za m'ma 1950 ndi 1960.Iwo ali ndi makhalidwe otsika matenthedwe madutsidwe, otsika mayamwidwe madzi ndi mkulu compressive mphamvu.Ntchito yake yotchinjiriza matenthedwe, kukana kwapadera kwa nthunzi permeability, mphamvu yopondereza kwambiri, komanso kukonza kosavuta ndikuyika.Kapangidwe ka XPS ndikuwotcha ndi kutulutsa utomoni wosungunuka wa polystyrene kapena copolymer yake ndi zowonjezera pang'ono ndi zotulutsa thovu mumtundu wina, kuutambasulira ndi chopukutira komanso m'malo opangira vacuum (njira zina sizifunikira) Kugwiritsa ntchito XPS m'munda womanga kumaphatikizapo (1) zipangizo zotetezera kutentha m'makoma amagulumagulu, (2) kumanga maziko a khoma la pansi; (3) denga lamkati ndi lakunja; (5) ) Misewu ikuluikulu, mabwalo a ndege, malo oimika magalimoto ndi malo ena omwe amayenera kuletsa kugwa kwapanjira ndipo ayenera kukana kukakamizidwa;(6) Kusungirako kuzizira ndi zipangizo zina zosungiramo kutentha kwapansi.
