Sun rays aim directly at our heart: daylight is a very positive stimulant for the human psyche. Therefore, generous glass expanses in architecture are not only a design element, but also increase the inhabitants' well-being.

French doors guide the light into the depth of the room and exude generousness and elegance. At the same time, French windows by HBI help to improve the energy balance and lower the electricity demand. This enables building owners to invite light and nature into their home - and leave energy losses right in front of their door.
