Let's go!

As the weather gets colder and the nights grow longer, there is one thing on our minds at EcoChoice; how to prepare our timber for the winter weather. Notoriously harsh, the colder months bring a number of weather-related challenges, including rain, ice and snow. But does this mean your timber needs treating before winter arrives?

Find out everything you need to know in this guide. 

How Timber Responds to Cold Weather

There are a few weather changes we see as the weather gets colder. Aside from temperature fluctuations, the main features to be aware of include:

  • Increased humidity and rain
  • Ice and hail
  • Snow

For instance, the excess water produced by each can lead to swelling, warping and rot. Water which turns to ice can also expand small holes and cracks, creating larger areas of damage which need to be addressed.

All these weather conditions can cause issues for less durable timber species. Older, worn wood might also run into trouble, making it important you take the time to treat and maintain your exterior timber.

Does Timber Need Treating Before Winter?

Autumn and winter weather can negatively affect some timber, but not all.

If you have invested in a very durable timber, for example, then it is unlikely to be affected by the higher levels of humidity and water. A Durability Class 1 timber or Use Class 5 – such as Ekki, Greenheart or Iroko – can be used for marine applications and remain in constant contact with water, so excess rain will not be a problem.

(Not sure what durability or use class your timber is? Take a peek at our Durability vs Use Class guide to learn more).

However, if your timber is more than a few years old, we would consider treating the wood. This will help replenish lost oils and give it a little boost before harsher weather conditions.

Less durable timber will need extra TLC to stay strong and stable during bad weather. A species such as Pine or Spruce, for example, will not withstand rain and snow as easily as Opepe or Yellow Balau, making treatment essential.

How to Treat Timber Before Cold Weather

Treating less durable or older timber earlier in the year is a great idea. The dry, warmer weather will make it simpler to treat and ensure your wood is properly protected by the time cold, wet weather arrives.

If you have missed the summer window for treatments, though, do not panic! You can still protect your timber after the autumn or winter weather has arrived.

One of the main focuses of your treatment should be waterproofing your wood. You can find waterproof timber protectors in clear coats,for example the Osmo Wood Protector (which is also biocide-free), as well as timber oils which replace your wood’s natural oils and create a waterproof surface. Auro has a great range of natural, eco-friendly oils and waxes.

You can also use stains to protect your timber and freshen up its colour, helping your outdoor timber products look their best year after year.

Before applying any treatments, make sure that you have sanded off the top surface of any previous treatments to allow the product to soak into the timber.

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.
