Benefits at a glance
How it works
Thanks to a patented hardware design, effiAIR offsets the sash about ¼” (≈ 6 mm) from the frame along the entire perimeter.
In this position:
-
Used, stale air exits through the top of the window.
-
Fresh, cool air flows in through the bottom
-
The window remains virtually locked, offering RC‑2 level security—even in ventilation mode
Technical Highlights
-
Frame‑sash offset: ~6 mm (¼ inch) gap all around for continuous air exchange
-
Complies with RC‑2 burglary resistance for one‑pane configurations, depending on window size
-
Effective reduction in humidity and odors backed by independent studies (e.g. Technical University of Münster) showing temperature drop rates of approx. 35.6 °F → 32.9 °F in 10 minutes
