If you’re working with steel framing, understanding thermal break tape is critical — especially in Perth builds. While it might seem like a small detail, it plays a major role in preventing condensation, improving energy efficiency, and meeting compliance requirements.
In this guide, we explain what thermal break tape is, where to use it, and why it’s becoming standard practice across WA construction projects.
—What Is Thermal Break Tape?
Thermal break tape is a self-adhesive insulating strip applied between steel framing and external cladding materials. Its main purpose is to reduce heat transfer and prevent condensation forming inside wall systems.
- Acts as a barrier between hot and cold surfaces
- Reduces thermal bridging through steel studs
- Helps prevent moisture build-up inside walls
It’s most commonly used in steel frame construction where metal can conduct temperature rapidly.
—Why Thermal Break Tape Is Important in Perth
Perth’s climate creates the perfect conditions for condensation issues — hot days followed by cooler nights can cause moisture to form inside wall systems.
- Prevents internal condensation in external walls
- Improves overall thermal performance
- Helps meet NCC and energy efficiency requirements
- Protects internal linings like plasterboard
Without a proper thermal break, you risk long-term damage such as mould, corrosion, and reduced insulation performance.
—Where Should You Use Thermal Break Tape?
Thermal break tape is typically installed in external wall systems, especially when using steel framing.
Common Applications
- Behind external cladding (fibre cement, metal sheeting)
- On steel studs and tracks
- In wall systems exposed to temperature variation
It works alongside your wall system, including insulation and internal linings like: Plasterboard Products
—Thermal Break Tape vs Sarking: What’s the Difference?
These two products are often confused but serve different purposes.
- Thermal Break Tape: Applied directly to framing to stop thermal bridging
- Sarking: Installed as a reflective membrane for moisture and air control
For best results, both are often used together in a complete wall system.
—How to Install Thermal Break Tape
Installation is straightforward but needs to be done correctly for maximum performance.
Basic Installation Steps
- Ensure steel framing is clean and dry
- Apply tape directly to studs and tracks
- Press firmly to ensure full adhesion
- Install cladding over the top
Consistency is key — gaps or missed sections can reduce effectiveness.
—What to Look for When Choosing Thermal Break Tape
Not all tapes are the same. Quality matters, especially in commercial or high-performance builds.
- Strong adhesive backing
- UV resistance (if exposed during install)
- Suitable thickness for compliance
- Compatibility with your wall system
It’s also important to match it with your framing system, such as: Steel Framing Products
—How Thermal Break Tape Works with Insulation
Thermal break tape and insulation work together to improve overall thermal performance.
- Tape reduces heat transfer through framing
- Insulation controls internal temperature
- Combined system improves energy efficiency

—Final Thoughts
Thermal break tape might seem like a minor addition, but it plays a major role in protecting your build. In Perth conditions, it’s essential for preventing condensation, improving energy efficiency, and ensuring your wall systems perform long-term.
When used correctly alongside insulation and quality materials, it helps deliver a stronger, more durable build — which is exactly what every project needs.
