The short answer
Fibre-cement and timber cladding both offer a weatherboard look but behave very differently. Fibre-cement (cement, sand and cellulose fibre) is rot-proof, low-maintenance and usually non-combustible, holding its finish for decades with only occasional cleaning, and it is favoured where fire performance matters. Timber (cedar, larch and similar) gives a genuine natural appearance that fibre-cement can only imitate, but it weathers and needs periodic finishing, or you accept it silvering. Fibre-cement is the practical, fire-friendly, fit-and-forget option; timber is the choice for natural authenticity and character. Costs overlap, with both broadly in the mid range. The decision turns on whether you prioritise low maintenance and fire performance or natural looks.
Fibre-cement is often pitched as the low-maintenance answer to timber. The two compete on looks but diverge sharply on upkeep and fire behaviour.

Appearance
Timber offers genuine grain, depth and natural colour change, ageing with character and able to be finished or left to silver. Fibre-cement comes as smooth or woodgrain-effect planks and flat panels, pre-finished in a wide colour range; it imitates timber convincingly from a distance but lacks the genuine texture of wood up close. If authenticity is the deciding factor, timber leads. If you want a consistent, controlled finish that stays the same colour for years with no re-coating, fibre-cement is the more predictable choice.
Maintenance, fire and durability
This is where the two diverge most:
- Fibre-cement — rot-proof, insect-proof and dimensionally stable, needing only occasional cleaning; pre-finished boards do not need painting. Crucially, most products are non-combustible, achieving a top reaction-to-fire rating.
- Timber — naturally durable species last well, but the wood weathers visibly; to keep its original colour it must be re-coated periodically, otherwise it silvers. Timber is combustible, which can restrict its use on certain buildings.
For fire-sensitive buildings — flats, terraces, homes near a boundary — fibre-cement's non-combustibility is a major practical advantage that timber cannot match.
Installation and handling
The two are fitted to battens over a ventilated cavity, but the practicalities differ. Timber is light, cuts and fixes with ordinary tools, and is forgiving on site, but it relies on good detailing — a ventilated cavity, corrosion-resistant fixings, protected end grain and ground clearance — to reach its full life. Fibre-cement is dense, heavy and brittle, so larger sheets are a two-person lift, the framework must suit the weight, and the board can chip or crack if mishandled or fixed too tightly. Crucially, cutting fibre-cement produces dust containing crystalline silica, so it must be cut with the correct blades and on-tool dust extraction and appropriate protection — it is not a material to cut casually. For these reasons fibre-cement is usually installed by an experienced contractor, whereas simple timber cladding is more accessible. Both have detailed manufacturer fixing guidance that should be followed.
Cost and lifespan
Pricing overlaps; the difference in value comes from upkeep and fire performance rather than upfront cost.
| Factor | Fibre-cement | Timber |
|---|---|---|
| Fitted cost | ~£60–£120/m² | ~£50–£120/m² |
| Maintenance | Occasional clean | Periodic re-coat or silver |
| Fire | Usually non-combustible | Combustible |
| Lifespan | Often 50 years+ | Decades (species/detailing) |
| Look | Imitates wood | Genuine natural |

How each ages
Weathering is a major difference. Timber visibly changes over time — left untreated it silvers to grey, sometimes unevenly across elevations, and finished timber needs its coating refreshed periodically as the wood moves. Many owners value this living surface, but it is upkeep. Fibre-cement is designed to stay close to its original appearance: pre-finished boards hold their colour for many years with only occasional cleaning, and the material does not rot, swell or warp. Paintable fibre-cement can be repainted if you want a change, but it is optional rather than necessary. So the contrast is between timber's character and weathering, which demands either maintenance or acceptance of silvering, and fibre-cement's stable, consistent finish that largely looks after itself. For a finish that stays the same for years, fibre-cement leads; for a surface with natural character, timber does.
Sustainability and end of life
The two materials have very different environmental profiles. Timber is renewable — responsibly grown, certified wood comes from managed forests, stores carbon, and can be reused, recycled or burned for energy at the end of its life with no plastic or cement involved. Its main environmental cost is the finishes some timber needs and, for less durable species, treatment. Fibre-cement is a manufactured board whose cement content carries a meaningful embodied-carbon footprint from its production, and it is not readily recyclable, generally going to landfill or hardcore at end of life. Set against that, its very long service life and minimal maintenance mean it rarely needs replacing and uses no coatings over the years. So timber tends to lead on renewability and disposal, while fibre-cement's edge is durability and a maintenance-free life. As with most cladding choices, the most honest comparison weighs sourcing, lifespan and end-of-life route together rather than judging on the raw material alone — and certified timber and a long-lived fibre-cement system can both be reasonable choices.
Which should you choose?
Choose fibre-cement if you want minimal maintenance, a long life, a finish that stays put, and — importantly — good fire performance; it is the default where building control favours non-combustible cladding, such as on flats or taller buildings. Choose timber if you value a genuine natural appearance and character, like the idea of wood that silvers or can be finished, and are prepared for the upkeep. Note that fibre-cement is heavy and brittle to cut (needs dust control and the right tools), while timber needs a ventilated cavity and good detailing. Both must comply with Building Regulations; on sensitive buildings, fibre-cement's fire classification often makes it the simpler route, but always confirm the specific product's certification.
Frequently asked questions
Is fibre-cement cladding better than timber?
For low maintenance and fire performance, fibre-cement is the stronger choice — it is rot-proof, holds its finish and is usually non-combustible. For genuine natural looks and character, timber leads but needs upkeep and is combustible. Better depends on whether you value fit-and-forget durability or authentic wood.
Does fibre-cement look as good as real wood?
Woodgrain-effect fibre-cement planks look convincingly like timber from a normal distance, but up close they lack the genuine texture and colour variation of real wood. For a controlled, uniform finish fibre-cement is excellent; for true natural character, timber still has the edge.
Which is safer in a fire, fibre-cement or timber?
Fibre-cement is usually classed as non-combustible and achieves a top reaction-to-fire rating, while timber is combustible. For fire performance, fibre-cement is the safer choice, which is why it is favoured on flats and taller buildings. Always check the specific product's certified classification.
