Proposed ENERGY STAR® Updates

The Environmental Protection Agency has recently released its proposed changes to the performance criteria of the US Energy Star windows program.


One of the proposed changes is to set the maximum U-Factor of the Northern climate zone to 0.25-0.27. While an estimated 47% of window products currently do not meet this proposed target, most Innotech products* meet these requirements with dual pane glass and all Innotech products exceed these requirements with triple pane glass.

Energy Star Proposed Changes vs. Innotech Products

*To achieve 0.27 with e366, the panes must be 5mm/5mm. This qualifies all InnoNova products except the Tilt + Glide door, which remains at 0.28. This data applies to InnoNova products only.
