Fibre Cement.
Fibre cement is a moderate CO₂ material. Always check whether older panels contain asbestos before renovation. New panels have a long lifespan and are a practical facade choice. Read the numbers together with function, lifespan, detailing and the specific building element.

How to use this assessment
The assessment of fibre cement is a first decision basis. Carbon numbers, density and lifespan give a point of comparison, but the material must always be read together with structure, moisture, fire requirements, detailing, maintenance and the condition of the existing building. A good material choice is therefore both a data question and an architectural judgement. The useful next step is to clarify which questions should be examined further before the material is specified in a project.
What is fibre cement?
Fibre cement is a composite of cement, sand, and cellulose fibres. Used for facade cladding, roof panels, and interior cladding. The products (including Cembrit and Eternit) are durable, maintenance-free, and frost-resistant. Older products contained asbestos — safe disposal is crucial.
Carbon Footprint Compared
Negative carbon footprint (green) indicates carbon storage. Data based on EPD averages from ECO Platform and estimates per EN 15804.
Typical Applications

- check_circle Roof panels (flat pitched roofs)
- check_circle Plinth panels
- check_circle Interior cladding in damp rooms
In Renovation
Fibre cement is common on 1960s–1980s single-family houses. Many renovate the facade by adding insulation and installing new fibre cement or timber cladding. Remember asbestos check on older panels.
Questions about fibre cement
Do old fibre cement panels contain asbestos?
Fibre cement produced up to approximately 1988 may contain asbestos. Eternit products from this period are asbestos-containing and require specialist handling for demolition and disposal. Contact an authorised asbestos remover.
Is fibre cement maintenance-free?
Almost. Fibre cement is resistant to frost, moisture, and UV light. It can be painted but does not require it. Moss growth can occur and is removed with low-pressure washing.
Is fibre cement sustainable?
Fibre cement contains cement with its associated carbon footprint, but the cellulose fibres are renewable. The products have a relatively long lifespan. Recycling of fibre cement is limited in practice.
What are the alternatives to fibre cement on facades?
Brick, timber cladding, reclaimed brick and reclaimed fibre cement panels are alternatives. Timber cladding has a lower carbon footprint; natural slate is the most durable.
