Perimeter Termite Barrier Installation
A complete and continuous barrier, as per AS 3660.1
What Is Perimeter Termite Barrier Installation?
Perimeter termite barrier installation is a critical component of termite management systems. Installed around the external perimeter of a building where wall systems meet with the concrete slab, perimeter termite systems help maintain a complete and continuous barrier.
Unlike localised termite management methods that protect individual penetrations or construction joints, perimeter termite barriers must form a complete and continuous barrier around the entire building perimeter. The termite management system should always return to where it started because termites will track around barriers in search of an opening, also making careful detailing around corners and structural columns essential to maintaining a complete and continuous system, as per AS 3660.1.
Perimeter termite barriers are typically installed following slab construction and prior to framing and work in conjunction with service penetration protection, construction joint protection and under slab termite management systems to form a complete termite management system.

Why Perimeter Protection Is Crucial
Complete & Continuous Protection
Perimeter termite barriers rely on continuity of protection around the entire building footprint. Any gaps, discontinuities or incorrectly detailed interfaces can compromise the overall termite management system and create potential concealed termite entry pathways.
Integration With Building Types
Modern construction projects incorporate a wide range of wall types including brick veneer, cladding, post frame construction and precast concrete panels. Each construction method requires a specific perimeter installation detail.
Integration With Other Termite Management Methods
Perimeter termite barriers are designed to integrate with service penetration protection, construction joint protection and underslab termite management systems to create a complete termite management system, as per AS 3660.1.
Perimeter Barrier Installation Methods
Different construction systems require different perimeter termite barrier installation methods. The installation detail selected depends on the wall construction type, framing system and architectural design requirements.
Standard Brick Veneer (250mm Sheet)
For standard brick veneer construction, a 250mm termite barrier sheet is installed beneath the external wall framing and extends into the brickwork zone.
This installation detail helps maintain continuity of termite protection around the building perimeter while allowing future termite activity to remain visible for inspection purposes.
Post Frame Brick Veneer (C-Section)
Post frame brick veneer construction commonly requires a C-Section installation detail. The termite barrier is fixed to the wall frame and folded into the brick course, forming a profile similar to the shape of the letter “C”.
This detail accommodates post frame construction methods while maintaining continuous termite protection around the building perimeter.
Cladding Systems (150mm Sheet)
For standard cladding construction, a 150mm termite barrier sheet is installed beneath the external wall framing to provide continuous perimeter termite protection.
This installation method integrates with a wide range of cladding systems and assists in maintaining continuity of termite management measures around the building envelope.
Block Work Section
Blockwork construction commonly requires a a 100mm installation detail. The termite barrier is fixed to the top of the slab on the external side of the dowel bars, ensuring the perimeter barrier is flush with the slab edge.
It is important that the slab is trowelled smoothly around the dowel bars so the termite barrier can sit nice and flat on the slab before the blocks then sit on top of the barrier.
Precast Panel Construction (L-Section)
Precast concrete panel buildings typically require an L-Section installation detail. The termite barrier is fixed to the internal face of the precast panel where the wall frame will be installed.
The barrier extends beneath the bottom plate and folds up between the wall frame and the precast panel to maintain continuity of termite protection.
The termite barrier cannot be installed beneath the precast panel itself as this would compromise the grouting integrity and structural performance of the panel installation. The L-Section detail provides an effective solution while accommodating the construction requirements of precast panel construction

What is perimeter termite barrier installation?
Perimeter termite barrier installation involves installing a termite management system around the external perimeter of a building where wall systems interface with the concrete slab. The barrier forms part of the overall termite management strategy and is designed to work in conjunction with service penetration protection, construction joint protection and under slab termite management systems.
Why must perimeter termite barriers be continuous?
Perimeter termite barriers must form a complete and continuous system around the entire building perimeter. Any gaps, discontinuities or incorrectly detailed interfaces can create breaks in the termite management system.
Termites naturally search for the path of least resistance and can track around the perimeter of a building looking for an unprotected entry point. In many ways, this is similar to finding a door in a maze. If a gap exists anywhere within the perimeter protection system, termites may eventually locate that opening and gain concealed access into the building.
Careful detailing around corners, wall junctions, columns and other structural interfaces is therefore essential to maintaining the integrity and continuity of the termite management system.
What perimeter detail is used for standard brick veneer construction?
Standard brick veneer construction typically uses a 250mm termite barrier sheet installed beneath the external wall framing and extending into the brickwork zone. This detail helps maintain continuous termite protection around the building perimeter while allowing future termite activity to remain visible for inspection.
What is a C-Section perimeter detail?
A C-Section detail is commonly used for post frame brick veneer construction. The termite barrier is fixed to the frame and folded into the brick course, forming a profile similar to the shape of the letter “C”. This installation method accommodates post frame construction while maintaining continuous perimeter protection.
What perimeter detail is used for cladding systems?
Standard cladding construction typically uses a 150mm termite barrier sheet installed beneath the external wall framing. This detail provides continuous perimeter termite protection while integrating with a wide range of cladding systems.
What is a U-Section perimeter detail?
A U-Section detail is commonly used for post frame cladding construction. The termite barrier is side fixed to the wall frame before being folded over and sandwiched between the wall frame and the external cladding system. This installation method maintains continuity of protection while accommodating post frame construction methods.
What is an L-Section perimeter detail?
An L-Section detail is commonly used for precast concrete panel construction. The termite barrier is fixed to the internal face of the precast panel where the wall frame will be installed. The barrier extends beneath the bottom plate and folds up between the frame and the precast panel to maintain continuity of termite protection.
Why can’t termite barriers be installed beneath precast concrete panels?
Installing a termite barrier beneath a precast panel can compromise the grouting integrity and structural performance of the panel installation. For this reason, perimeter termite protection is typically achieved using an L-Section detail installed to the internal face of the panel where the wall frame is constructed.
Can perimeter termite barriers be installed around steel columns?
Yes. Perimeter termite barriers can be detailed around steel columns and other structural elements. Careful cutting, fitting and sealing of the barrier system is required at these critical areas.
Do perimeter termite barriers comply with AS 3660.1?
Perimeter termite management systems are installed in accordance with manufacturer specifications, project requirements and applicable Australian Standards. AS 3660.1 provides guidance for termite management systems used in new building work and forms an important part of termite risk management throughout construction.
