ZaZogona,Mtundu wowala bwinokapena mtundu wakuda ndi wabwino kuvala
Posankhazovala zogona, kusankha mtundu ndikofunika kwambiri.Malinga ndi zomwe zaperekedwa, kuwala ndi plamu zogonera ndiakulimbikitsidwa ngati chisankho chachikulu pazifukwa izi:
Kuwala ndi kumvekapajamas ndi zambirioyenera malo okhala kunyumba:Kuwala ndi kumvekamitunduimatha kupanga nyumba yamtendere komanso yabwino, yomwe imathandizira kupumulathupi, maganizo ndilowa m’malo opumula.
Pewani kusankha mitundu yakuda kapena yowala:Mitundu yakuda kapena yowala imatha kukhala ndi zinthu zovulaza monga formaldehyde, zomwe zitha kuwononga thanzi.
Komanso, posankhaZovala zanyumba zovala, azinthu za nsalu ndi zofunika kwambiri.Nsalu zovomerezeka zimaphatikizapo ulusi wachilengedwe monga thonje, silika wa mabulosi, modal, ndi zina zotero, komanso ulusi wopangidwanso wa cellulose.Tnsalu izi zili ndi gkupuma movutikira komanso kupuma bwino,nazonsooyenera kuvala kunyumba.
Mwachidule, chifukwa cha thanzi ndi chitonthozo, ndi chisankho chanzeru kusankha kuwala ndi kumvekazovala zogona. Kusankha koteroko sikumangopereka mwayi wovala bwino, komanso zimatsimikizira thanzi ndi chitetezo cha nyumba
