Kuyambira mu Industrial Revolution, anthu apanga mwamphamvu mafakitale ndi ukadaulo.Ngakhale kuti moyo uli wosavuta kuposa kale, moyo wa anthu wapita patsogolo kwambiri, koma dziko limene anthu amadalira kuti apulumuke nalonso lawonongeka kwambiri.Kutentha kwa dziko ndi nkhani yovuta kwambiri.Zonsezi zimachitika chifukwa cha kutentha kwa mafuta, malasha, ndi zina zotero, kapena kudulidwa ndi kuwotcha.Ngati sitikhala ndi chidziwitso choteteza chilengedwe, madzi a m'nyanja adzakwera ndipo anthu adzakumana ndi masoka owononga.Mwamwayi, maiko ambiri tsopano ayamba kuchepetsa mpweya wa carbon, ponse paŵiri m’moyo ndi m’makampani, akuyembekeza kuchitapo kanthu kuti ateteze chilengedwe.

Pomanga nyumba, zipangizo zokongoletsa zachilengedwe ndi zomangira ziyenera kugwiritsidwanso ntchito momwe zingathere.Mwachitsanzo,matabwa a mineral wool, matabwa a ubweya wa miyala,ndi matabwa a fiberglassamagwiritsidwanso ntchito kwambiri pomanga uinjiniya ndi kukongoletsa mkati.Iwo sangangothandiza kukonza chilengedwe, komanso kukwaniritsa zofunikira za zomangamanga.Kutenga mchere wonyezimira bolodi monga chitsanzo, zopangira ndi slag ubweya, slag ubweya ntchito mafakitale zinyalala slag (kuphulika ng'anjo slag, mkuwa slag, zotayidwa slag, etc.) monga zopangira zazikulu, thonje filamentous inorganic CHIKWANGWANI amapangidwa ndi kusungunuka, pogwiritsa ntchito njira yothamanga kwambiri ya centrifugal kapena jekeseni ndi njira zina.Kuphatikiza apo, bolodi logwiritsidwa ntchito la mineral wool litha kusinthidwanso kukhala zinthu zatsopano.Pankhani ya zida zopangira, sizongokonda zachilengedwe zokha, komanso denga labwino kwambiri lotulutsa mawu, lomwe limagwiritsidwa ntchito kwambiri pakukongoletsa m'maofesi ndi malo ena.Choncho tikamasankha zipangizo zokongoletsa, tiyeneranso kusankha zinthu zoteteza chilengedwe.
