Gulu la vacuum insulation potengera ma fiberglass cored material, zida zatsopano zotchinjiriza zotenthetsera kutentha, zimakhala ndi magawo atatu akuluakulu: zida za fiberglass, zida za getter / desiccants ndi zotchingira zapamwamba.
Monga gulu lapadera lopangidwa ndi zida zapakati ndi zigawo zoteteza, zimaphatikizidwa ndi kukwezeka kwa vacuum insulation ndi kusungunula kutentha kwapang'onopang'ono, ndikuyimitsa kutentha kwa convective kutengera kutentha kwamatenthedwe.Ndi bwino koyambirira matenthedwe madutsidwe otsika kuposa 0.0025 W/m.K
Poyerekeza ndi zida zotchinjiriza zachikhalidwe za PU, gulu lopulumutsa mphamvu komanso lokonda zachilengedwe silikhala ndi ODS (zinthu zowononga ozoni) popanga komanso kugwiritsa ntchito kwambiri zinthu zotchinjiriza zotentha monga mafiriji a cryogenic, chotenthetsera madzi amagetsi, makina ogulitsa, mafiriji, matanki osungiramo ziwiya za firiji, etc.
Tikhoza makonda kukula & mawonekedwe anu, ngati mukufuna fiberglass cored zinthu zingalowe kutchinjiriza mapanelo, chonde omasuka kulankhula nafe.
