Si loo hagaajiyo waxqabadka kulaylka ee cutubyada galaaska ee wajiga, waxaa lagu talinayaa in la isticmaalo muraayad labanlaab ah ama saddex-jibbaaran.

Iyada oo la adeegsanayo tiknoolajiyad laba-jibbaaran, gaas aan firfircoonayn ayaa lagu dahaadhay labada muraayadood ee galaaska. Argon-ku wuxuu u oggolaanayaa iftiinka qorraxda inuu dhex maro isagoo xaddidaya heerka tamarta qorraxda ee ka baxda galaaska.

Qaab-dhismeedka saddex-geesoodka ah, waxaa jira laba godad oo argon ka buuxa oo ku jira saddex muraayadood. Natiijadu waa hufnaan tamar oo wanaagsan iyo hoos u dhac cod oo ay weheliso yaraanta uumiga, maadaama ay jirto kala duwanaansho heerkul oo yar oo u dhaxaysa gudaha iyo galaaska. In kasta oo ay si fiican u shaqeyneyso, haddana muraayadda saddex-geesoodka ah waa ikhtiyaar qaali ah.

Si loo kordhiyo cimriga, galaaska la dahaadhay waxaa laga sameeyaa lakab polyvinyl butyral (PVB). Muraayadda la dahaadhay waxay bixisaa faa'iidooyin badan, oo ay ku jiraan xannibaadda gudbinta iftiinka ultraviolet-ka, codka oo wanaagsan, iyo laga yaabee tan ugu muhiimsan, isku xirnaanta marka ay burburto.

Iyada oo la eegayo arrinta saameynta dhismaha iyo iska caabbinta qaraxyada, dibadda dhismaha wuxuu u shaqeeyaa sidii safka ugu horreeya ee difaaca gantaalada. Sidaas darteed, sida wajiga uga jawaabo saameynta ayaa si weyn u saameyn doonta waxa ku dhaca dhismaha. Dabcan, way adag tahay in laga hortago in galaaska uu jabo ka dib marka uu waxyeello weyn soo gaaro, laakiin galaaska la dahaadhay, ama filim ka hortagga jajabka oo lagu mariyo muraayadaha jira, ayaa si fiican u hayn doona jajabyada galaaska si looga ilaaliyo dadka dhismaha deggan qashinka.

Laakiin wax ka badan oo ka kooban muraayadda jabtay, waxqabadka daahyada ee ka jawaab celinta qaraxa waxay ku xiran tahay isdhexgalka u dhexeeya awoodaha walxaha kala duwan.

"Marka laga soo tago adkaynta xubnaha shaqsiga ah ee ka kooban nidaamka daahyada-derbiga, lifaaqyada looxyada dabaqa ama alwaaxyada spandrel waxay u baahan yihiin fiiro gaar ah," ayuu qoray Robert Smilowitz, Ph.D., SECB, F.SEI, maamulaha sare, Protective Design & Security, Thornton Tomasetti – Weidlinger, New York, ee WBDG's "Naqshadeynta Dhismayaasha si looga hortago khataraha qarxa."

"Xidhiidhadani waa inay noqdaan kuwo la hagaajin karo si loo magdhabo dulqaadka wax soo saarka iyo in la waafajiyo kala duwanaanshaha qulqulka dabaqyada iyo isbeddellada kulaylka iyo sidoo kale in loo qaabeeyo in lagu wareejiyo culayska cufisjiidadka, culayska dabaysha, iyo culayska qaraxyada," ayuu qoray.
