Technical Specification

Chimneys are subject to significant corrosion attack by flue gas condensates, particularly from solid fuel heavy oils and condensing appliances. Prima Plus and Prima Plus 1mm are specifically designed and manufactured to resist this corrosion. It is the only stainless steel single wall chimney system in the world to have passed the internationally recognised Gastec corrosion test.
