Poyerekeza ndi miyala ina yachilengedwe, miyala ya mapiri ophulika ili ndi makhalidwe abwino kwambiri. Kuwonjezera pa makhalidwe onse a miyala yamba, ilinso ndi kalembedwe kake kapadera komanso ntchito zake zapadera. Mwachitsanzo, tenga basalt. Poyerekeza ndi miyala ya marble ndi ina, miyala ya basalt ili ndi mphamvu yochepa ya radioactivity, kotero ingagwiritsidwe ntchito mosamala m'malo okhala anthu, ndipo sizingapangitse ogula omwe amasankha miyala yokongoletsera mkati kuti asasinthe. Mwala wa mapiri ophulika ndi wolimba ndipo ungagwiritsidwe ntchito kupanga mbale ya miyala yopyapyala kwambiri. Pambuyo popera bwino pamwamba, kuwala kumatha kufika madigiri opitilira 85, mtundu wake umakhala wowala komanso woyera, ndipo mawonekedwe ake ndi okongola komanso okongola. Umagwiritsidwa ntchito kwambiri pamitundu yonse ya nyumba zokongoletsa khoma lakunja, bwalo la msewu wa boma ndi pansi pa nyumba zogona. Ndi mwala womwe umakondedwa kwambiri pamitundu yonse ya nyumba zakale, nyumba zaku Europe ndi nyumba za m'munda. Umakondedwa kwambiri ndipo umalandiridwa ndi makasitomala kunyumba ndi kunja. Zipangizo za miyala ya mapiri ophulika sizimakhudzidwa ndi nyengo, nyengo ndi kulimba; kuyamwa kwa mawu ndi kuchepetsa phokoso zimathandiza kukonza malo omvetsera; zosavuta komanso zachilengedwe, kupewa kuwala kumathandiza kukonza malo owonera; Kuyamwa madzi, kuletsa kutsetsereka ndi kukana kutentha zimathandiza kukonza malo okhala ndi maso; ntchito yapadera ya "kupuma" imatha kusintha chinyezi cha mpweya ndikukonzanso chilengedwe. Mitundu yonse ya maubwino apadera imatha kukwaniritsa mafashoni atsopano a anthu amasiku ano pofunafuna zinthu zosavuta komanso zachilengedwe, zomwe zimalimbikitsa kuteteza zachilengedwe ndi zachilengedwe. Chida chopangira miyala yamoto chopangidwa ndi mapiri.
