Let's go!

When looking for sustainable cladding options, you have two heavyweight contenders: aluminium and timber. Some projects may use plastic, but for the sake of an eco-conscious battle, we have instantly taken plastic out of the running. When looking at aluminium and timber, though, you have two fairly sustainable options which both work to protect a building. Which, then, should you choose?

To make the decision easier, we have weighed up the pros and cons of each in this no-nonsense guide.

Timber Cladding Benefits

Timber is the most popular choice for both interior and exterior cladding, providing a natural, versatile option for your project. Some of the main benefits of sustainable timber cladding include:

  • A natural aesthetic – Even with a timber-look aluminium, you cannot beat the natural beauty of real wood. For high-quality aesthetics and biophilic design perks, it is the best choice for every cladding project.
  • Incredibly durable – Timber (when maintained) can last for thousands of years. With the right TLC, you will not need to replace timber in your lifetime and it can stay looking fresh year after year with a little maintenance.
  • Design versatility – Easily cut, profiled and moulded, you can make your timber boards look the way you want. From sizing to carving details, create a bespoke style easily for your dream cladding look.
  • Renewable and biodegradable – Timber wins major sustainability points thanks to being a natural, raw resource which will never run out, and being biodegradable at the end of its life. It is also carbon sequestering, absorbing CO₂ from the atmosphere earning plenty of green points.

Aluminium Cladding Benefits

Aluminium is a smart alternative to timber if wood does not meet your needs. The benefits of aluminium cladding include being:

  • Easy to maintain – As a corrosion-resistant metal, aluminium needs very little maintenance to stay looking its best.
  • Fire resistant – It boasts great fire resistance, making it a smart choice when safety concerns are an issue, such as in areas prone to wildfires or buildings with strict fire safety measures in place.
  • Uniform in appearance – Unlike timber boards (which vary in colour and knots from board to board), aluminium boards can be made with a uniform appearance for a more polished, timber-like look.

Timber Cladding Disadvantages

Though timber comes out ahead in terms of benefits, that does not mean it is perfect. There are some factors to be aware of before making your choice, including:

  • Maintenance – Timber requires more maintenance than aluminium, with some species needing coatings to prevent rot. Other species with high durability might not need these coatings, but could benefit from finishes (e.g. oils and stains) to keep them looking their best.
  • Fire risk – Unlike aluminium, timber can pose a potential fire risk. However, it is not quite as much of a danger as some people think, and there are plenty of treatment options out there to bring it up to fire regulation standards.

Aluminium Cladding Disadvantages

When looking at the disadvantages, how does aluminium compare? Aside from lacking the natural beauty of real timber, you should be aware that aluminium:

  • Scratches and dents – Aluminium is known to wear when used as cladding, with both scratching and denting common problems which you do not see as frequently with timber cladding.
  • Can cost more – For a fake timer option, aluminium can be pretty costly. It often comes with a higher price tag than other faux timbers, and can even be more expensive than some real timber species.

Timber Cladding Comes Out Ahead

Though aluminium cladding can be great in situations where you cannot use timber, if you can, then it is always best to opt for the real thing. You cannot beat the look of a beautiful timber species, and with so many sustainable perks to this natural material, it will keep your construction in line with the growing eco-conscious building movement.

Frequently asked questions

Do you supply timber for domestic uses?

Yes, we supply timber for domestic applications as well as commercial and public constructions. From garden decking to shed cladding, we will be happy to supply smaller deliveries for home use.

Is your timber FSC-certified?

Yes, all timber we supply is FSC or PEFC certified and sourced from independently verified responsibly managed forests. If we can’t find your request in FSC/PEFC certified timber we’ll suggest an alternative that is certified or clearly note that the offer is minimum EUTR.

Where does EcoChoice deliver to?

EcoChoice delivers to construction sites, warehouses and homes across the UK, as long as there’s access and unloading for our trucks.

What are the best timber species for exterior use?

There are many different timber species suitable for exterior use and which is the best for your project depends on your requirements. In general, though, we recommend EkkiGreenheartOpepe and Oak for heavier civil/marine uses. For intermediary external use such as decking, where the timber needs to be both strong and durable but not on the same level as civil engineering (bridgespiling, etc) we usually supply CumaruIpe, Jatoba, and Balau. And for the lighter exterior use where the timber is non-structural such as cladding, we deliver CedarLarchThermowood and others.

Which timber is the most durable?

Durability Class 1 timbers are the most durable. This of course depends on the use (hazard) class they’ll be in service for. For direct ground and water contact such as sleepers, fenders, marine piling, etc, Ekki and Greenheart are known to be the most durable timbers available. For decking and cladding where there’s no direct ground contact (use class 3) there’s a much wider range of timbers such Larch, Cedar, Thermo modified Pine or Ash and others.

What’s the best timber for internal cladding?

Internal cladding, where your timber is not in ground and not exposed to the elements can be classed as either use-class 1 or 2 – in which case most timbers will meet this durability criteria. That is not to say they’ll be the best, since internal environments have lower humidity (moisture) levels than outside. So in these cases, it’s best to go for a kiln-dried timber cladding board as these are more stable and delivered already in lower MC (moisture content) than the usual fresh sawn timbers sent to external applications. A word of caution – as timber reacts to variations in moisture, it’s best to avoid cladding any areas inside your bathroom.

How can I make decking less slippery?

The first thing is to ensure your deck boards are kept clean from leaves and other debris which will, over time, cover the surface and make it more slippery. Grooved boards can be used to improve grip if installed and used perpendicular to traffic, so especially useful in narrow passages and footbridges. Lastly, you can add our Grip-Choice strips: these are a mix of epoxy with aggregates that add gripping ridges to your deck area. Gripchoice is an easy way to make decking less slippery and safer, especially over large areas or where there’s high traffic. We can pre-install Grip-Choice strips for your decking before delivery or ship the strips separately to add to your existing deck’s grooves as a retro-fit solution.

What wood machining services do you offer?

We can offer planing, sawing, drilling and profiling of rough-sawn wood to any profile you require: from handrails to large port fenders.

Can you supply pre-drilled timber?

Yes, we will be happy to provide pre-drilled timber which is tailored to your needs for quick installation, thus saving you valuable time on site.

What cladding profiles do you supply?

We provide a wide range of cladding profiles, including tongue and groove, featheredge and shiplap. You can check the standard profiles here – but we can also match or custom make profiles to suit your specific needs.

Does timber change colour?

Yes, timber is well-known for changing colour over time. Some species can darken quickly right after installation, and like most untreated wood will eventually weather to a beautiful silver-grey. Interior timber is less likely to change colour (depending on conditions), and timber can be stained, painted or treated with UV-resistant oils to reduce colour change.

Do I need to treat exterior timber?

Some timbers such as Oak and Ekki, can withstand the strains of exterior use without any treatment. However, to extend the lifespan and maintain the aesthetic of your wood, we do recommend treating your timber with stains and oils. Pre-treated timber, such as ThermoWood and OrganoWood, are low-maintenance options which are more durable, but can have their life service extended by applying a clean and stain maintenance schedule.

Do I need to treat interior timber?

Depends on what area the timber is being used. For floor joists and timber rafters, it is common to see timber treated, or least very well kiln-dried. Other uses such as flooring may benefit from varnishing while internal timber cladding for decorative purposes shouldn’t require any treatment other than if you want to change its colour with different types of stains or oils.

Where are you based?

We’re based in Cambridge, UK, and coordinate multiple sawmills all over the world to manufacture your order. We then organise delivery with a range of hauliers so that your orders gets to your site on time.

What are the usual decking sizes?

Timber decking is usually 21x140mm or similar. For heavier applications where there’s more load and traffic, we deliver 35 or 45mm thick boards (such as Hastings Pier). Narrower boards are also possible: 95-90mm is a standard width – but we can manufacture whatever size you require.

What are the usual cladding sizes?

Typical cladding section sizes are 18×95 and 18x145mm although we can always custom make a section to suit your project’s design requirements. That includes waney edge boards in Oak or Chestnut as well as extra wide 195mm boards.
