Vous avez peut-être déjà vu ces bouteilles qui percent le plafond pour apporter de la lumière, notamment dans les favelas, sans dépenser une fortune en fenêtre?
Well, the tubular daylighting devices, it’s a bit the same principle, more elaborate and with a cost of course.
A windowless room is very unpleasant to live and highly energy-consuming, since there is no natural light, it is necessary to turn on artificial lights constantly. A solution for these rooms are the conduits of natural light.

The tubular daylighting devices are obviously perfectly tight.
Note: prefer rigid tubes than flexible tubes, which are less efficient.
You can add intensity regulators to meter the desired light, which can be nice in the bedrooms, for example.
Tubular daylighting devices can be installed on different roofs : shingles, zinc, slate, vegetated, tile or slate. It is possible to install them as well on the vertical walls.
