Çenteyên foil ne jehrî ne. Hundirê çenteyê insulasyona pelê aluminiumê materyalek insulasyonê ya nerm e wekî kef, ku rêzikên ewlehiya xwarinê pêk tîne. Foila Aluminium xwedan taybetmendiyên astengî yên hêja ye, berxwedana rewa baş, û îzolekirina termal. Tewra ku germ di nav qata pelika aluminiumê ya hundurîn de bigihîje qata hewaya hewaya PE ya navîn, di tebeqeya navîn de vekêşana germê dê çêbibe, and it is not easy to penetrate the outer aluminum foil layer, so as to achieve a good heat insulation effect.
