PERFORMANCE

WonderWindows have exceptional energy performance, offering options of R3.3, R4.5, and R6.8, typically 2 to 5 times more energy efficient than conventional low e double pane glass windows, when one considers whole building R-value including sash & window framing.

Natural Wood
  • The sash can be installed as fixed units, or with proper detailing and installation, as operable lift-out units. Emergency egress requirements may be met for operable windows providing a minimum 22” clear width opening and 5.7 sf minimum area. WonderWindows are designed to fit 24" o.c. framing can meet this criteria with opening heights of 40" and above. 

  • R-value is based on calculations using LBNL's WINDOWS program following NFRC standards. NFRC100/300/500 simulation with NFRC102 test validation, AAMA 101 Air/Water/Structure tests and ICC-ES listings are currently scheduled for 4Q 2019/ 1Q 2020.
