Window Size 47″x59″ 1200x1500mm with GLASS Ug 0,5W/m².K.
- ENERGIO PASSIV Uw : up to 0,66W/m².K – certified from PASSIV HOUSE INSTITUT DARMSTADT
- This translates to ANSI/NFRC imperial values of <0,14 Btu/(h.ft².F)*
*We have no NFRC testing for these high performance passiv windows – we have used 1W/m².K = 0,176 Btu/(h.ft².F) to transfer values in Imperial values
