Abstract

L'invention concerne une double fenêtre (1) qui est disposée entre un premier espace (2) et un second espace (3) dans une section ouverte (4) qui est ouverte sur le premier espace (2) et le second espace (3). La double fenêtre (1) comporte : une première fenêtre (5) ; et une seconde fenêtre (6) qui est plus proche du second espace (3) que la première fenêtre (5) et qui peut être déplacée relativement par rapport à la première fenêtre (5). Une couche polarisante (74) polarise la lumière qui est incidente depuis le côté premier espace (2), et permet à la lumière polarisée d'être émise vers le côté second espace (3).
