Round tube Ø 150mm, telescopic wall sleeve 350-680mm, blower door

VO/592937

This telescopic wall conduct with design extension is the perfect combination of design and energy efficiency, a visual highlight. The magnetic, ball-bearing backdraft damper integrated into the wall connection piece prevents cold air from entering the outer wall. The combination of the two magnetic backdraft dampers creates a thermal zone on the inside, allowing you to make a contribution to climate and environmental friendliness. Blower door (for low-energy houses) certified.
