Kodi zitsulo zagalasi ziyenera kutenthedwa?

Zitsulo zagalasi ndizodziwika bwino chifukwa cha malo ake oyera komanso mawonekedwe ake amakono, koma chitetezo—ndi kutsatira malamulo—zimabwera patsogolo. M'madera ambiri, International Building Code (IBC) ndi miyezo yofanana nayo imafuna magalasi oteteza alonda ndi zogwirira ntchito: magalasi ayenera kukhala ndi laminated ndikupangidwa ndi galasi lotenthedwa bwino kapena lolimba ndi kutentha kuti apewe kugwedezeka ndikuchepetsa ngozi yobwera chifukwa cha kusweka.

Kwa eni nyumba, galasi lofewa limagwiritsidwa ntchito nthawi zambiri chifukwa ndi lolimba ndipo limasweka kukhala zidutswa zazing'ono, zosaopsa kwenikweni; komabe, galasi lofewa (lofewa lolumikizidwa ndi interlayer) likufotokozedwa kwambiri—makamaka pa ntchito zamalonda, zazitali, kapena pa khonde—chifukwa limagwira ntchito limodzi likasweka ndipo limachepetsa chiopsezo cha kugwa. Kusintha kwa ma code am'deralo (ndi zofunikira za mphepo/katundu) nthawi zambiri kumatsimikizira ngati kutentha kokha ndikokwanira kapena kufewa ndi kofunikira.
Opanga mapulani ayeneranso kuzindikira zosintha zatsopano za ma code zomwe zimakhudza kapangidwe ka makina (mwachitsanzo, zofunikira pa njanji zapamwamba kapena mphamvu zinazake zonyamula katundu). Nthawi zonse onetsetsani malamulo a dipatimenti yomanga nyumba ndikugwiritsa ntchito magalasi ovomerezeka omwe amakwaniritsa miyezo yachitetezo ya ASTM/ANSI kapena CPSC musanayike.
