Iireyili zeglasi zithandwa ngenxa yemigca yazo yokubona ecocekileyo kunye nenkangeleko yanamhlanje, kodwa ukhuseleko—kunye nokuthobela ikhowudi—kuza kuqala. Kwimimandla emininzi i-International Building Code (IBC) kunye nemigangatho enxulumene nayo ifuna iglasi yokhuseleko kwiigadi kunye nee-handrails: iiphaneli zeglasi kufuneka zifakwe i-laminate kwaye zakhiwe ngeglasi efudumeleyo ngokupheleleyo okanye eqiniswe ngobushushu ukuze imelane nempembelelo kwaye inciphise ingozi yokuqhekeka.
Kubanini bezindlu, iglasi eqinisiweyo isetyenziswa kakhulu kuba iqinile kwaye iyaqhekeka ibe ziingceba ezincinci, ezingenabungozi kangako; nangona kunjalo, iglasi eqinisiweyo (ii-plies eziqinisiweyo ezibotshelelwe kwi-interlayer) ichazwa ngakumbi—ingakumbi kwiindawo zorhwebo, ezinde, okanye ezifakelwe kwibalcony—kuba ibambelela kunye xa yaphukile kwaye inciphisa umngcipheko wokuwa. Utshintsho lwekhowudi yendawo (kunye neemfuno zomoya/umthwalo) zihlala zigqiba ukuba iqinisiwe yodwa yanele okanye i-laminated iyimfuneko.
Abayili kufuneka baqaphele uhlaziyo olutsha lwekhowudi oluchaphazela uyilo lwenkqubo (umzekelo, iimfuno zeereli eziphezulu okanye amandla athile omthwalo). Soloko uqinisekisa imithetho yesebe lezakhiwo lendawo kwaye usebenzise iglasi eqinisekisiweyo ehlangabezana nemigangatho yokhuseleko ye-ASTM/ANSI okanye ye-CPSC ngaphambi kokufakwa.
