How to Choose the Right Softwood Cladding

In this blog post, WL West explore the exciting range of softwood cladding on the market and look at the key criteria for selecting the best cladding for your building project. 

There are two different types of cladding – fresh sawn and machined – so first let’s examine the difference between these options.

Fresh-Sawn vs Machined Cladding: Understanding the Difference

Fresh Sawn Cladding

Fresh sawn cladding is supplied in its green state, meaning it contains a high moisture content and will season (dry out) over time. During this process, movement such as shrinkage, warping, and surface checking (small cracks) may occur. This is a natural characteristic of fresh sawn material and does not affect the structural integrity. Profiles include traditional waney-edge, feather-edge and square edge, which are ideal for a range of homes and buildings, including barns, garden rooms and garages.

Machined Cladding

Common machined profiles include tongue and groove (TGV), shiplap, and halflap, which interlock or overlap for a tight, water-proof seal. Machining ensures that each board has the same dimensions and profile, resulting in a more uniform appearance and easier installation. As the timber is kiln-dried it can offer better dimensional stability compared to fresh sawn options. A versatile choice, machined cladding can be used internally or externally and the range of profiles suit both modern or traditional properties.

Cladding Installation Guidelines

To ensure a long-lasting and stable installation, we recommend:

  • Fixings: Use stainless steel nails or screws to prevent staining and corrosion. 

  • Pre-drilling: Recommended to minimise splitting.

  • Follow any guidelines on overlapping/spacing etc. to allow for the natural expansion and contraction of the timber.

  • Ventilation: Ensure proper airflow behind the cladding to prevent moisture buildup.

Our expert team have detailed all the aspects to consider when choosing softwood cladding, take a look at our comprehensive list below.


7 key considerations when choosing softwood cladding

Durability & Natural Resistance

  • Douglas Fir: Moderately durable. Has good resistance to decay but benefits from a protective treatment in exposed areas. Contains resin, which helps with weather resistance. May require treatment or regular maintenance for long-term durability.

  • Larch: More durable than Douglas Fir. Has a higher resin content, making it naturally more resistant to moisture, decay, and insect attack.

  • Western Red Cedar: The most durable of the three. Naturally resistant to decay, insect damage and moisture, making it ideal for cladding with minimal treatment.

Stability & Movement

Fresh sawn cladding will be less stable and more prone to movement than kiln dried machined cladding. The higher moisture content of the green timber will gradually reduce as it air dries, and this will likely result in some shrinkage and cupping in the less stable timber species.

  • Douglas Fir: Fairly stable but prone to some movement as it dries. Can develop surface checking (small cracks).

  • Larch: Moderate stability but more prone to splitting than Douglas Fir due to its density. Careful installation is needed.

  • Western Red Cedar: The most stable of these softwood options, with minimal movement, making it a great choice for cladding.

Workability

The harder the timber species is to work with, the longer it is likely to take to install the cladding, which in turn impacts on the cost of the project.

  • Douglas Fir: Relatively easy to work with, though it can be resinous.

  • Larch: Harder and denser than Douglas Fir, making it more challenging to work with. Its tendency to split needs to be considered.

  • Western Red Cedar: The easiest to work with due to its softness and fine grain. 

Appearance 

With UV exposure, all untreated timber will weather to a silvery-grey over time. Treating the timber with a quality UV protection oil can help maintain the original colour for longer if desired.

  • Douglas Fir: Unique pinky/apricot ranging to pale reddish-brown tones with defined growth rings. 

  • Larch: Warm golden to reddish-brown, with varied grain patterns and small knots.

  • Western Red Cedar: Very distinctive light brown to reddish tones. Homegrown cedar is more knotty than Canadian timber. If a surface treatment is required, the absence of resin within the timber makes it an ideal choice for painting or staining.

Cost & Availability

  • Douglas Fir: Generally, the most affordable and widely available. Our fresh sawn local Douglas Fir comes from a responsibly managed local estate in West Sussex.

  • Larch: Mid-range in cost, though high-quality larch can be more expensive. WL West Timber use British Larch for our fresh sawn cladding profiles (eg. Feather-edge) and Canadian Larch for the machined profiles (eg. TGV).

  • Western Red Cedar: The most expensive due to its durability and popularity, but its longevity may offset the higher upfront cost. We have two options for our customers: homegrown Western Red Cedar for fresh sawn cladding and Canadian Western Red Cedar for machined cladding profiles.

Lifespan 

There is a significant difference in the lifespan of different timber species, which should be taken into account in your cost-benefit analysis of the options. The longer lasting species may well justify their higher cost, as the cladding need not be replaced as frequently.

  • Douglas Fir: 15-30 years

  • Larch: At least 30 years

  • Western Red Cedar: 30-60 years

Sustainability

Last but not least, you will no doubt want to consider the sustainability and carbon footprint of your cladding. Check that your timber cladding supplier is a member of a body like Timber Development UK. Members of TDUK (like WL West) are signatories to the mandatory Responsible Purchasing Policy which is audited annually and proves the legality of the timber that the company supplies. 

WL West can source fresh sawn Douglas Fir, Larch and Western Red Cedar from well-managed British woodlands. In fact, our PEFC certified Douglas Fir comes from an estate just a few miles down the road from our HQ, making the carbon footprint of the timber very low! 

Machined cladding often comes from Canada, so although the timber is from responsibly managed forests, it does have to travel a long distance to the UK.

Which softwood cladding should you choose for your project?

If you need a balance of affordability and durability, Larch is a solid choice. If you want longevity with minimal maintenance, Western Red Cedar is the best but pricier. If budget is a key concern, Douglas Fir offers a good compromise but may require more maintenance.
