What is the Best Timber to use for Exterior Cladding?

Timber cladding is used in modern architectural designs all over the world to create some of the most impressive residential and commercial buildings. Since the Australian climate can be particularly tough, many people want to know what is the best timber to use for exterior cladding. 

The failure or early aging of timber cladding is typically not due to the wood species chosen. Instead, the fault is usually because the timber has not been treated correctly, installed optimally or maintained properly. 

When timber cladding suppliers understand the unique properties and suitability of each species, timber cladding can have an impressively long life. In fact, quality architectural timber should be able to withstand the harsh elements and maintain its natural beauty for years to come.

Mortlock Timber offers specially selected timber species that are suited to timber cladding, these include:

Timber species are also available in different finishes which include:

  • Shou Sugi Ban finish (charred timber)
  • Natural Oil
  • Sioox Weather Protection (weather timber look)
  • Custom Stain Options

Is your timber treated properly?

The durability and longevity of products such as timber decking and cladding can be enhanced by treating the timber. The treatment process helps the wood repel termites and resist the growth of fungi.

Although the specific process varies depending on the wood species, treating timber usually involves inserting preservatives into the timber cells via a carrier agent such as water or oil. In Australia, particular standards and minimum preservative penetration requirements must be met.

Consider natural protection: Shou Sugi Ban.

Shou sugi ban is a traditional Japanese method of charring timber with fire to make it more durable. The black carbon layer that forms on the surface of the wood protects the wood from moisture and harsh weather elements.

Although shou sugi ban was traditionally used on Japanese Cedar, Mortlock Timber has refined the process to translate on a wide range of hardwoods. Burnt Ash, Fine Sawn Jarrah and Spotted Gum are particularly suited to the shou sugi ban method because of their durability and stability. 

The shou sugi ban technique is making a modern comeback, thanks to its handmade process and striking aesthetic. Charred timber cladding is surprisingly versatile and has been used in modern architectural projects as both interior and exterior Timber wall. Far superior than black paints and stains, shou sugi ban cladding is the artisanal choice.

Want durable cladding? Design makes all the difference.

When timber cladding is exposed to the elements, it’s the design that often determines how well it performs. Timber naturally moves, expands and retracts in response to the environment. The most durable cladding designs find harmony with this phenomenon and work with the natural movements of timber rather than ignoring them.

Our Trendplank profile is a concealed fixed cladding system which has been expertly designed to allow for the natural movements of timber. The boards are installed using ‘end matching’, which is a tongue and groove profile that improves waterproofing. The Trendplank profile can be created with a wide range of hardwood timber species, allowing you to achieve the look you want. 

Using timber is less exposed areas like ceilings and soffits also reduces maintenance, with little or no exposure to rain or the suns UV rays, the timber is protected and no maintenance. For example the Aria Apartments project in Swanbourne used our Trendplank Blackbutt Timber cladding on the exterior ceiling of the communal area. Using timber in this way means timber can still be used to create warmth and atmosphere with maintenance.

Maintenance: Giving your timber a bit of love.

When coated properly, designed well and chosen suitably, timber requires little maintenance.

In exterior applications that are exposed to harsh sun, it is important to check the timber as UV light can lead to yellowing or silvering of the timber. Preserving the aesthetic integrity and restoring the natural colour of timber is easily done by regular cleaning and recoating. Although it varies from project to project, recoating exterior timber cladding every 12-18 months is recommended to preserve its appearance and natural colour.

The other option to reduce maintenance is to allow the timber to weather. This means very little maintenance even on external timber, however the colour of the timber will fade to a silver grey colour, this can sometimes reduce the maintenance from 12-18 months up to 4-5 years depending on the application and location of your project.

Take your modern architectural design to the next level with timber cladding.

Exterior timber cladding is an excellent way to elevate any residential or commercial project. Wood is one of the most environmentally friendly building materials and offers sensory beauty in a way that synthetic materials cannot compete with.
