Lightweight shaft and wall duct

Quick and easy-to-install solutions for new builds or renovations

Our lightweight and easy-to-install lightweight shafts with excellent insulating properties can be installed with minimal distance to combustible building materials. The lightweight chimney, made from calcium silicate fire protection panels, is equipped with different Jeremias inner pipes depending on the application, or alternatively, serves as an installation shaft for CE-certified inner pipes.

For solid fuel heating systems, we recommend the FURADO-F or FURADO-F-LAS systems (for room-air-independent operation). When operating an oil or gas heating system, the FURADO-A system or the space-saving FURADO-A-LA30 is the top choice.

In addition, our LUX-NOVA or LUX-ECO fire protection ducts offer innovative solutions for wall, ceiling, or roof penetration of flue gas pipes.

NOTE
xx = The distances to combustible materials are diameter-dependent
We therefore refer you to our performance declarations, which are available for download

For chimney heights of approximately 5 meters or more, please order additional length elements of 250 mm, 500 mm, and 1000 mm, as the shafts are longer than our inner pipes
Usable lengths for shaft elements: 250 = 225 mm / 500 = 475 mm / 1000 = 975 mm
Usable lengths for inner pipes: 250 = 190 mm / 500 = 440 mm / 1000 = 940 mm
