Weatherboard vs. brick: a look at the pros and cons of each

Material

Weatherboard cladding is available in various materials, the most popular being timber. A variety of native species of wood are used to construct Australian timber weatherboards, including spruce, cypress pine, blackbutt, flooded rose gum and jarrah.

Brick has an unmistakable reddish-orange colour, with various types and styles available. The most common type of brick used in Australian house construction is the standard burnt clay brick, made from natural clay or clay mixed with other materials such as shale. The clay is moulded into shape, usually a rectangular block and then fired in a kiln until the brick is hardened and reaches the required strength.

Price

A notable difference between the two materials is cost. Bricks are more expensive upfront as they take longer to lay. You can expect much less upkeep and maintenance in return for this higher cost. Weatherboard is significantly cheaper up front but requires continual maintenance, such as regular painting and repair work.

A budget friendly option

Weatherboard is a much more budget-friendly option than brick, with prices available to suit all budgets. Prices for timber weatherboards can range from around $7 per linear metre for a baltic pine panel all the way to around $85 per linear metre for a cedar panel. A weatherboard supplier should be able to recommend the best type of timber weatherboard to use for your budget and project.

A sustainable choice

Weatherboard cladding is inherently sustainable, making it an essential consideration. Both timber weatherboards and fibre cement weatherboards are frequently crafted from materials that are 100% recyclable, although specific products may vary in this regard. 

Timber weatherboards, in particular, are sometimes sourced from sustainable forests or reclaimed wood, further enhancing their eco-friendly appeal. Furthermore, when compared to alternative weatherboard options like aluminium, timber weatherboards consume less energy during the manufacturing process.

Suited to Australian weather conditions

Weatherboard is well suited to the Australian climate due to its natural thermal insulation, breathability, and durability. The cladding's breathability allows for proper ventilation and moisture control while not stopping mould and decay; these properties help prevent its growth and speed.

Additionally, the weatherboard used in Australia is designed to withstand harsh weather, including extreme temperatures, UV exposure, and moisture. These properties help ensure long-term protection of the material.

Continuous maintenance is required

While the tasks involved in maintaining weatherboard boards are relatively simple, they need to be carried out regularly. Failing to do so can lead to weatherboard slats rotting, decaying, warping and being susceptible to pest infestations.

To protect against pest infestations, remember to treat your weatherboard slats regularly, particularly if they're timber; aim to treat them at least once every ten years. To protect against rot and decay, keep an eye on your gutters and drain pipes to minimise moisture getting into your weatherboard.

Lack of insulation from the material

Timber weatherboard panels have lower thermal mass compared to bricks, which reduces their ability to store and release heat efficiently. Also, weatherboard materials tend to have higher thermal conductivity, making it easier for heat to transfer through each panel. Any gaps and joints in weatherboard cladding can also contribute to heat loss or gain.

As we mentioned, weatherboard can range from $7 per linear metre to $85 per linear metre. The price is dependent on the supplier, the size of the panel and the type of timber. You can also expect to pay around $50-$120 per hour for an experienced cladding professional.

Highly durable

Bricks are renowned for their durability, making them an excellent choice for the Australian climate. They can withstand extreme weather conditions, including intense heat, UV radiation, heavy rain, and strong winds. This resilience ensures that brick provides long-lasting protection for your home against harsh elements, reducing the risk of damage and the need for frequent repairs.

Fire resistant

Australia's landscape is prone to bushfires, particularly in certain regions. Bricks offer significant fire resistance, providing a protective barrier that helps prevent the spread of flames and reduces the vulnerability of your home to fire damage. Brick is a non-combustible material, providing added peace of mind and enhanced safety for homeowners, particularly in areas prone to bushfires.

Low maintenance costs

Bricks require minimal maintenance, making them a practical choice for homeowners. Unlike other materials that may deteriorate or require regular painting or sealing, bricks retain their structural integrity and colour over time with little upkeep. They are resistant to rot, decay, and pests, reducing the need for frequent repairs or treatments.

Long term cost-effectiveness

Bricks provide a high level of long-term cost-effectiveness for homeowners. While the initial investment in bricks may be higher than other building materials, their durable nature and low maintenance requirements can result in savings over time.

High upfront cost

While you can save money over time, the high upfront cost of bricks can be a disadvantage. The cost can vary significantly based on several factors, including the type of brick selected, such as clay bricks or concrete bricks, the size of the bricks, and the quality or aesthetic features desired. At the time of writing, the cost of 1000 clay bricks ranges from $1250 to $2000.

Prices for clay bricks are usually expressed per 1000 bricks and have risen significantly over recent years due to market conditions. Remember that the cost per brick doesn't include additional expenses such as mortar, skilled labour for installation, or any other materials required for the brickwork.

Time-consuming construction process

A time-consuming construction process isn't necessarily a concern if the brick construction time fits with your prospective timeline. However, it's essential to keep in mind that the construction of a brick house or exterior will take longer than if you were to use weatherboard cladding for the same build.

The installation and building process with brick involves several stages, including site preparation, foundation work, brick laying, mortar application, and curing. The time required for each stage can vary based on factors such as the project's size, the design's complexity, and weather conditions.

Bricks can vary in cost depending on the type of brick you choose, the amount, the quality and the individual supplier. As mentioned above, you can expect to pay between $1250 - $2000 for 1000 common clay bricks. For a professional bricklayer, expect to pay between $50 - $120 per hour.

When it comes to deciding between weatherboard and brick for your project, there are a few factors to consider. Weatherboard offers affordability, sustainability, and design versatility, but it does require regular maintenance and may have lower insulation capabilities. On the other hand, brick provides high durability, fire resistance, and low maintenance, albeit with a higher upfront cost. Take into account your budget, long-term maintenance needs, insulation requirements, and the local climate when making your decision. It's advisable to consult with a professional for personalised advice regarding your desired building project.
