Metaloterm AT

The Metaloterm® AT system is a modular twin wall insulated chimney system, made of stainless steel, with a high quality insulation and no thermal bridges. Metaloterm® AT is suitable for high temperature, non-condensing applications with flue gasses in negative pressure. The system is not only chimney fire resistant but also reusable afterwards. Therefore the system is ideally suited for applications such as wood-fired stoves and open fireplaces. For Passive houses the Metaloterm® assortment provides the Iso-block which can be combined with AT. Due to the proven quality Metaloterm® AT has a 30 year guarantee.
