The EXPO INOX roof/floor crossing module is designed to ensure maximum safety for flue systems that pass through structures made with combustible materials such as wood and is an excellent alternative to the masonry flue. It is the first system tested in accordance with the new visions of the harmonised product standards EN 1856/1 and EN 1859, which are SIGNIFICANTLY MORE IMPROVED than the previous ones.

Even under these extreme conditions, the system achieved the outstanding G00 designation under VENTILATED conditions both during normal operation and at temperatures up to 1000°C.
