STABILE MFS is a roof-crossing element able to increase levels of prevention and protection from fire using new materials and thanks to innovative technical solutions. Is not just a roof-crossing element with an insulating and fireproof function, but it is an integral part of the chimney system: a real flue that you can install in direct contact with the wooden roof or slab, which is really important for technicians who can get their work simplified and improved during design and installation. This dual function (fire prevention – flue system) allows STABILE MFS to ensure a significant reduction in the external diameter: up to 40% less than a traditional system. In case of chimney soot fire (1000° C inside the duct), STABILE MFS ensures a contact temperature with the adjacent wood of 80°C, which is compliant with the EN 1859. Therefore, a reduction of the high temperatures of more than 90%, which is mainly due to the interaction between the performance of the innovative internal insulating material and the peripheral ventilation system.
