METALOTERM MF - Double-walled, pre-insulated&modular
Highlights
The MF system is a modular twin wall insulated flue/chimney system, made of stainless steel, with a sealing ring. MF is a universal flue/chimney system which is suitable for both high and low temperatures, non-condensing and condensing applications with flue gasses in positive and negative pressure. It can resist a chimney fire. Therefore the system is suited for a wide range of applications such as boilers, stoves and ovens.
The product range also contains a wide variety of silencers. For Passive houses the assortment provides the Iso-block which can be combined with MF. The system can also be used for CHP applications, in this case a special VITON® sealing ring might be necessary. Due to the proven quality Metaloterm® MF has a 10 year guarantee.
