Ehlotyeni, iglasi enye yesilivere ye-sunshade ephantsi-e inokumisa ngokufanelekileyo ubushushu belanga bungene kwigumbi kwaye ibonise imitha yobushushu obuvela ngaphandle.Nangona ithintela ukungena kwamanye amandla ashushu elanga ebusika, ukusebenza kwawo kokugquma kwe-thermal akuchatshazelwa kuba amandla elanga ebusika sisinye kwisithathu kuphela sehlotyeni.

Iglasi ye-sunshade low-e inemibala eyahlukeneyo ebonakalisayo kunye nokuhanjiswa kokukhanya okuphakathi, okwenza kube nemibala eqaqambileyo yokuhombisa kunye nesiphumo sokukhusela umgca wangaphandle.

Iingenelo zeglasi enye yesilivere ye-sunshade ephantsi:

Ukuhanjiswa kokukhanya okubonakalayo- ukwenza isiphumo esifanelekileyo sokukhanyisa ngaphakathi, ukuba nekhusi elithile ukusuka kumgca wangaphandle wokubona.

Ukuhanjiswa kwamandla elanga - i-sunshade coefficient yeglasi <0.5, ukunciphisa imisebe yelanga kwigumbi.

Umgangatho ophezulu kakhulu we-infrared reflectivity - i-coefficient yokudlulisa ubushushu obuphantsi inciphisa imvelaphi yobushushu bemitha kwigumbi.
