The paper presents a concept of two-cell window panes partitioned by polyethylene foil. A simplified method of calculating heat losses from the panes is discussed and the calculations verified by means of FLUENT software. The addition of polyethylene foil a pane may raise some doubts concerning light transmittance by the window panes. Thus, a method of checking the transmittance of visible radiation from the two-cell panes is described.

W artykule zaprezentowano koncepcję wkładu dwukomorowego ze środkową przegrodą wykonaną z folii. Przedstawiono również uproszczoną metodę obliczania strat ciepła przez wkład okienny oraz jej weryfikację przy wykorzystaniu programu FLUENT. Wprowadzenie folii polietylenowej do wkładu okiennego może budzić obawy odnośnie transmitancji światła przez taki wkład. Opisano więc sposób sprawdzenia transmitancji promieniowania widzialnego przez dwukomorowy wkład okienny.
