Dark rooms not only oppress the mood, but also cause a bad feeling in terms of energy balance. The lack of light must be replaced by artificial light sources. These need electrical power. This in turn drives energy consumption and costs money.
Simple renovation measures can do a lot here. You don't always need new windows. Transparent glass doors will use existing daylight much better. It's a smart solution that can become a true eye-catcher in the living ambience thanks to the great choice of designs.
Glass doors have diverse uses. A windowless hallway, an impractically placed living room on the North side of the building or a side room to become a walk-in closet: Glass doors let friendly sunlight flood into cool rooms and noticeably and sustainably improve the living feeling.
