WonderWindows have exceptional energy performance, 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.
WonderWindows are fixed multi-pane acrylic windows installed between 24" on center framing.
Up to $30/sf LESS installed cost than low-e argon-filled double pane in thermally improved aluminum frames.
- WonderWindows are fixed multi-pane acrylic windows installed between 24" on center framing.
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.
