Muzhizha, imwe sirivheri sunshade yakaderera-e girazi inogona kunyatso kumisa kupisa kwezuva kupinda mukamuri uye kuratidza kure-infrared kupisa mwaranzi kubva kunze.Kunyangwe ichidzora kupinda kweimwe solar yekudziya simba munguva yechando, mashandiro ayo ekudzivirira kwemafuta haakanganisike nekuti simba rezuva muchando rinongova chikamu chimwe muzvitatu cheiyo muzhizha.

Iyo sunshade low-e girazi ine akasiyana-siyana anotaridza mavara uye ine mwero mwenje transmittance, izvo zvinoita kuti iwedzere kuve neruvara yekushongedza mhedzisiro uye yekunze mutsara-we-sight shielding effect.

Zvakanakira zveimwe sirivheri sunshade low-e girazi:

Visible light transmittance- kugadzira yakakodzera mwenje wemukati, kuve neimwe pekugara kubva kune yekunze mutsara wekuona.

Solar energy transmittance - iyo sunshade coefficient yegirazi <0.5, inodzikamisa solar radiation mukamuri.

Yakanyanya yakakwira kure-infrared reflectivity - yakaderera kupisa kupisa coefficient inodzika kunze kwemashure kupisa mwaranzi mukamuri.
