The XD system is a double layered flexible flue system steel, made of stainless steel, with a smooth inner wall. XD 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 renovation situations as a shaft liner.
