Single-flue chimneys - Specific technical features

Chimney termination seal
The flue termination is a sensitive part of the chimney as it is subject to the acidic condensation of the combustion gases. All of our chimney terminations are therefore made out of austenitic stainless steel 1.4404 (316L). This protection makes the external insulation (mineral wool) tight, whatever the expansion conditions..

Inspection door
Our easy-to-dismantle inspection door enable you to access and inspect the chimney during maintenance. They come in 150 x 250mm, 250 x 250mm or 400 x 500mm sizes (contact us for made-to-measure hatches). BEIRENS inspection door can come insulated against heat as an option.
