Qalabka dahaadhidda faakuumka ee ku salaysan maaddada fiberglass-ka ah, walxo cusub oo tamar wanaagsan leh oo loogu talagalay dahaarka kulaylka, waxa uu ka kooban yahay saddex qaybood oo waaweyn: maaddooyinka asaasiga ah ee fiberglass, agabka gter-ka/qallaaska iyo laminates-yada sare.
Sida isku-dhafka khaaska ah ee ka samaysan walxaha asaasiga ah iyo lakabyada ilaalinta, waxay ku dhexjirtaa sareynta vacuum insulation iyo kuleylka kulaylka-yar-yar, si wax ku ool ah u joojiso wareejinta kulaylka korantada si ay ugu habboonaato kuleylka kuleylka.Iyada oo leh kulayl hore oo aad u wanaagsan oo ka hooseeya 0.0025 W/m.K
Marka la barbar dhigo qalabka dahaarka PU ee dhaqameed, tamarta-badbaadinta iyo deegaanka-saaxiibtinimo guddiga dahaarka vacuum kuma jiraan wax ODS ah (ozone walxaha baabi'iyo) ee habka ay wax soo saarka oo si ballaaran u codsanaya in alaabta kulaylka sida qaboojiyaha cryogenic, kululeeyayaasha biyaha korontada, mashiinada iibka, qaboojiyaha, haamaha kaydinta weelka qaboojiyaha, iwm.
Waxaan u habeyn karnaa cabbirka iyo qaabka sida shuruudahaaga, haddii aad raadineyso xayndaabyada daboolka xuubka fiberglass-ka ah, fadlan xor u noqo inaad nala soo xiriirto.
