MF - Double-walled, pre-insulated & modular
MF (formerly METALOTERM MF) is a modular, double-walled and pre-insulated flue gas system and exhaust air system made of stainless steel with a special internal lip seal. It can be used universally at low and high temperatures with and without condensation in negative and positive pressure. MF is therefore suitable for a wide range of applications such as condensing boilers, low temperature and solid fuel fireplaces and is soot fire resistant. We have summarized all the advantages of the flue gas pipe for you:
MF is a modular, double-walled and pre-insulated flue gas/exhaust air system made of stainless steel with a special internal lip seal. It can be used universally at low and high temperatures with and without condensate accumulation in negative and positive pressure. The inner and outer walls are made of high-quality stainless steel.
MF is a modular, double-walled and pre-insulated flue gas/exhaust air system made of stainless steel with a special internal lip seal. It can be used universally at low and high temperatures with and without condensate accumulation in negative and positive pressure. The inner and outer walls are made of high-quality stainless steel. When thermally heated, the inner shell can expand without stress.
The high-quality thermal insulation prevents unwanted cold and thermal bridges. The system also includes a special acid and temperature-resistant lip seal inserted at the factory. Very high soot fire resistance is guaranteed. Use as a supply and exhaust air system is also possible.

MF is a flue gas and exhaust air system for almost all areas of application. The universally applicable system is suitable for ovens, industrial plants, tiled stoves, open fireplaces, condensing boilers, low-temperature and solid fuel fireplaces. In passive houses, the system can be combined with the Isoblock, a compact wall and ceiling penetration through combustible building materials. It can also be used as a supply and exhaust air system.
