Magonhi emakabati ekuratidzira ari mufiriji anowanzo gadzirwa negirazi rakapetwa kaviri rakaiswa pafuremu yemuviri wegonhi, uye madhisiki anowedzerwa pakati pegirazi rine mativi maviri kuti agadzire chisimbiso chakapetwa kaviri kuti agadzire girazi rinodzivirira kupisa, uye rinogonawo kuzadzwa nenitrogen ine thermal conductivity yakaderera. Kana kuti helium. Gonhi nekabhineti zvakabatana nemahinji.

Midziyo inodiwa kugadzirisa magonhi egirazi maviri akachengetwa mufiriji:

Muchina wekugadzira magirazi uchishandisa gasi otomatiki, muchina wekugadzira magirazi uchishandisa butyl coating, muchina wekuvhara magirazi uchishandisa sealant, muchina wekuisa aluminium, muchina wekuzadza desiccant, muchina wekutamisa framer uchishandisa aluminium spacer.
