Timber vs. Steel Framing: Which is Best for Your Home Build?

Making the Right Choice with Easyway Building Brokers

When planning your dream home, one of the most important decisions you’ll face is what type of framing to use. Timber and steel are the two most common framing materials in Australia, and each comes with its own strengths, weaknesses, and cost considerations.

At Easyway Building Brokers, we make the process simple by helping you compare your options and find the best fit for your budget, climate, and design goals. Let’s break down the key differences between timber and steel framing so you can make an informed decision.

🏠 TIMBER FRAMING: THE TRADITIONAL CHOICE

Timber has been the go-to framing material for Australian homes for decades. It’s widely available, easy to work with, and provides a natural, sturdy foundation for construction.

✅ Pros of Timber Framing:

✔️ Cost-Effective – Generally cheaper than steel, making it a budget-friendly option.
✔️ Easier to Work With – Builders and tradies are highly familiar with timber, reducing labour costs.
✔️ Energy Efficient – Timber is a natural insulator, helping to regulate indoor temperatures.
✔️ Eco-Friendly – Sustainable timber sources are available, reducing environmental impact.
✔️ Easier Modifications – Alterations or extensions can be done more easily compared to steel.

❌ Cons of Timber Framing:

❌ Termite Risk – If untreated, timber is vulnerable to termites and pests.
❌ Prone to Moisture Damage – Timber can warp or rot in humid or wet conditions if not properly maintained.
❌ Fire Risk – Though treated timber is more resistant, it’s still combustible.

🏗️ STEEL FRAMING: THE MODERN ALTERNATIVE

Steel framing has gained popularity for its durability, precision, and resistance to environmental threats. It’s commonly used in larger builds or areas prone to termites and harsh weather conditions.

✅ Pros of Steel Framing:

✔️ Strong & Durable – Steel doesn’t warp, twist, or shrink over time.
✔️ Termite & Pest Resistant – Unlike timber, steel is not a food source for termites.
✔️ Fire-Resistant – Steel frames do not catch fire, making them safer in bushfire-prone areas.
✔️ Ideal for Large & Complex Designs – Steel is stronger and can support larger open-plan layouts.
✔️ Moisture-Resistant – Perfect for humid and coastal regions where timber may struggle.

❌ Cons of Steel Framing:

❌ Higher Initial Cost – Steel framing materials and installation tend to be more expensive.
❌ Thermal Conductivity – Steel conducts heat and cold more easily, potentially affecting insulation.
❌ More Specialised Construction – Requires trained builders and specific tools, which can increase labour costs.

Choosing the Right Option for Your Build

The best framing choice for your home depends on your priorities:
✔️ If budget and flexibility are key, timber is an excellent, cost-effective choice.
✔️ If durability and resistance to pests or fire are top concerns, steel is worth the investment.
✔️ If you’re building in a coastal or humid area, steel’s moisture resistance makes it a safer bet.
✔️ If you want an eco-friendly home, sustainably sourced timber can be a greener option.

🌳 The Advantages of Timber Framing

Timber has long been a popular choice for home framing in Australia, offering a range of practical, aesthetic, and environmental benefits. Whether you’re building a new home or considering your options for renovations, timber framing provides versatility, cost-efficiency, and natural durability.

✅ 1. Cost-Effective & Readily Available

Timber is generally more affordable than steel, making it a great option for those looking to build on a budget. It is also widely available in Australia, reducing transportation costs and ensuring quick supply for construction projects.

✅ 2. Easier to Work With & Modify

One of the biggest advantages of timber is its flexibility in construction:

Simple to cut, shape, and install – reducing labour costs.

Easier to modify – Extensions, renovations, and modifications are simpler compared to steel.

Can be nailed directly – Unlike steel, timber allows for easy attachment of skirting boards, architraves, and fittings without the need for special fasteners.

✅ 3. Naturally Insulating & Energy Efficient

Timber provides natural thermal insulation, helping to keep your home warmer in winter and cooler in summer. Unlike steel, which conducts heat and cold, timber helps maintain a stable indoor temperature, leading to lower energy bills over time.

✅ 4. Environmentally Friendly & Sustainable

Timber is a renewable resource, making it one of the most sustainable building materials available. Many Australian suppliers offer sustainably sourced timber, ensuring responsible forestry practices. Plus, timber stores carbon dioxide, helping to reduce the home’s overall carbon footprint.

✅ 5. Minimal Expansion & Contraction

Unlike steel, which expands and contracts significantly with temperature changes, timber experiences minimal movement. This helps reduce the risk of:

Cracks in plasterboard and cornices

Visible screw heads on skirting boards and architraves

Structural stress from ongoing thermal expansion

✅ 6. Quieter & Less Prone to Noise Transfer

Timber absorbs sound more effectively than steel, resulting in a quieter, more comfortable living space. Steel frames, on the other hand, can produce popping or creaking noises as they expand and contract with temperature changes.

🌡️ How Steel Expands and Contracts with Temperature

Steel is highly responsive to temperature variations – when it heats up, it expands, and when it cools down, it contracts. This thermal movement can cause issues in homes framed with steel, particularly in climates with extreme temperature changes.

🔹 What Happens?

Steel can lengthen and shrink slightly as temperatures fluctuate, leading to small shifts in the structure.

These movements can cause plasterboard and cornices to crack over time, particularly at joints.

If the frame expands unevenly due to temperature differences across the structure, gaps may form, leading to visible imperfections in the walls and ceilings.

📌 Why Timber Doesn’t Have This Issue

Timber also expands and contracts, but at a much lower rate than steel.

Unlike steel, timber absorbs and releases moisture, which helps balance structural movement more gradually.

🔩 Why Screws Are Used for Skirting Boards & Architraves in Steel-Framed Homes

Due to the movement caused by temperature changes, certain elements in a steel-framed home require different installation methods. Skirting boards, architraves, and trims cannot be attached with small nails as they might in a timber-framed home.

🔹 Why?

Small nails don’t hold well in steel and are more likely to loosen over time due to movement.

Instead, screws are used to secure skirting boards and architraves, as they provide a stronger grip on the steel framework.

However, over time, the constant thermal expansion and contraction of steel can cause screw heads to become more visible, affecting the aesthetic of the interior finishes.

Workaround Solutions:

Countersinking screw heads and applying filler can help hide them, but movement may still cause them to resurface over time.

Using flexible adhesives alongside screws can help absorb movement and reduce visible damage.
