Freestanding wood fireplace with an exposed flue run up a concrete wall

Solinox Flue Systems

The part of the fireplace nobody sees and everybody needs

Solinox is the flue system we run with every wood-burning fireplace we install. All 304 stainless steel, in single and double wall, from 130 mm through to 400 mm.

All Signi Fires ranges

Single wall is used inside the room where the pipe is visible; double wall is used through ceilings, roof spaces and outside, because the air gap keeps the outer surface cool enough to pass safely through a timber structure. Getting the transition right is the single most important part of a safe installation — and the reason we do not sell flue over the counter without knowing the build.

The Range

Each of these is a family rather than a single product — sizes and finishes are chosen when we spec the build. Prices start at the smallest, plainest configuration of a family and climb with size and finish.
