Zvichienderana nekugadzirwa kweiyo yekutanga-layer magnesium oxide board, imwe yakawedzera dhizaini yemamiriro ekunze-kupokana yekushongedza granular zvinhu inowedzerwa pamusoro.Iyi nzira ichiri kuwanikwa kuburikidza nemasikirwo emasikirwo emakemikari anobatanidza zvimedu zvekushongedza zvakakwana neMgO, zvichiita chikwata chimwechete chakabatana.Iyo yese dhizaini yebhodhi inoramba yakakosha apo ichipa yakasarudzika yekushongedza maitiro.Inotsiva kudiwa kwezvinhu zvekupenda zvepamusoro senge pendi chaiyo yematombo, marble, mataira, uye kumwe kushongedza kwekunze kwemadziro.Zvinotonyanya kukosha, zvinoderedza zvakanyanya nguva inodiwa pamabasa emaoko.Kana madziro ekunze aiswa, hapana chikonzero chekuwedzera pendi kana yakaoma-yakarembera yezvinhu zvekushongedza.
