Frequently Asked Questions
Humid air is light, rises upwards in the shaft and is discharged at the highest point of the shaft through the welded-on haze hat of the shaft cover. At the same time, the cold penetration is reduced, thus preventing condensation of the humid air on the underside of the cover.
HUBER ventilation chimneys and venting chimneys made of stainless steel ensure optimum shaft ventilation and provide protection against small animals with insect-proof stainless steel screen.
