What is an insulated chimney?

An insulated (twin-wall) chimney consists of two pipes: an inner flue that carries the smoke and an outer protective casing. The space between them is filled with thermal insulation. It is the right choice where there is no masonry chimney or the existing one cannot be used.

Two walls

The inner pipe is made of acid-resistant stainless steel; the outer casing protects the system and gives it a neat finish.

Thermal insulation

Flue gases cool more slowly, which improves draught and reduces condensation.

Outside or inside

Installed on an external wall or inside the building, through the ceiling and roof.

Complies with EN 1856-1

Our products meet the European chimney standard and come with a 5-year warranty.

Outer casing colours

The casing can be left unpainted or finished in one of four RAL colours.

What does the system consist of?

The chimney is assembled from individual components, so it can be adapted to almost any building and heating appliance. The most commonly used parts are:

  1. 1
    Rain cap and top end piece

    Finishes the top of the chimney and protects it from rain and snow.

  2. 2
    Twin-wall pipe sections

    500 mm and 1000 mm lengths, combined to reach the required height.

  3. 3
    Wall bracket

    Securely fixes the chimney to the building wall.

  4. 4
    Twin-wall 90° tee

    Connects the horizontal flue connection to the vertical section of the chimney.

  5. 5
    Bottom end piece

    Adapter from twin-wall to single-wall pipe.

  6. 6
    Two-piece decorative wall plate

    Neatly covers the opening in the wall.

  7. 7
    Single-wall pipe sections and 90° elbow

    Together with a clamping connector, they connect the heating appliance to the chimney.

  8. 8
    Insulated condensate collector

    Collects condensate at the base of the chimney so it can be drained.
