Licht und Luft für den Keller durch Einbau eines Lichtschachtes
Lichtschächte sorgen dafür, dass Keller nicht ganz durch das Erdreich verschlossen werden: Sie lassen Licht und bei geöffnetem Fenster Luft in den Keller. Zur Herstellung von Lichtfenstern verwendet man einbaufertige Konstruktionen. Die Schächte bestehen meist aus Stahl, teilweise aus faserverstärkten Kunststoffen. Darauf werden gitterförmige Abdeckungen gelegt. Die Bauwirtschaft liefert diese Lichtschächte fertig zum Einbau in den üblichen Abmessungen.
