Immoblade MiniBlades

Our development team is currently developing your ultimate solar protection: Immoblade MiniBlades, a standard double-glazed window, with Immoblade's inclined louvers that fit in the space between glazing.

Each blade is about 10-mm wide and inclined optimally. More important: it is fixed.


This passive and simple solution has astonishing thermal performances, with a Sun factor (g) varying by a factor 3 between winter and summer, equaling performances of the best dynamic systems.

Associated with clear-glass glazing, it is compatible with fully standard double-glazed windows (e.g. 4-20-4), with a simple standard installation. It is also cost-effective over its life-time, with no maintenance, and no over-cost for glass-cleaning.

This product is protected by several international patents.

After the first demonstrators in 2019, Immmoblade MiniBlades is now in the process of industrialisation.

Immoblade MiniBlades received the label "1000 efficient Solutions" from the Solar Impulse Foundation in May 2020, following a sound process of peer-review of its environmental and economical benefits.


Miniaturised, the inclined lines of the Immoblade MiniBlades allow and exclellent transparency of the glazing.
