Product Information

Full details

The Tamlyn Aluminium External Corner is an essential trim component for professional installers and DIYers working with fibre cement cladding. Designed to wrap around 90-degree corners, this profile ensures a sleek, professional finish while providing critical water management. While it creates a robust and aesthetically pleasing edge, users must be diligent about maintaining the specific 5mm clearance requirement to ensure the long-term integrity of the cladding system.

FAQs

What is the primary purpose of this profile?

It provides a protective and aesthetic corner finish for fibre cement cladding at 90-degree angles while managing water runoff.

Is the 5mm clearance mandatory?

Yes, the 5mm clearance is required to allow for the natural thermal expansion and contraction of fibre cement planks.

Can this be used on corners other than 90 degrees?

No, this profile is specifically engineered for 90-degree corners.

How do I cut the aluminium to size?

Use a miter saw equipped with a non-ferrous metal cutting blade for clean, accurate cuts.

Does the black finish fade over time?

The aluminium is finished for exterior durability, but like any exposed building material, it should be kept clean to preserve its appearance.

Troubleshooting

Cladding board is too tight against the corner profile

Trim the edge of the cladding board to ensure a minimum 5mm gap for expansion.

Water pooling behind the corner trim

Verify that the corner is plumb and that the building wrap/flashing behind the trim is correctly shingled to shed water.

Pros and Cons

Pros

Ensures a clean, professional finish at corner junctions
High resistance to rust and weather-related degradation
Facilitates proper water drainage to prevent moisture buildup
Easy to integrate into standard fibre cement siding installations

Cons

Requires precise measurement to maintain the 5mm clearance gap
Non-flexible material requires accurate cutting for custom angles
Visible fasteners or caulking may be required for specific looks

Setup, Compatibility & Care

To install, ensure the corner profile is securely fastened to the wall framing using appropriate corrosion-resistant screws that do not interfere with the cladding planks.

Compatibility: Designed specifically for standard fibre cement cladding systems.
Clearance: Always maintain a 5mm gap between the cladding plank and the profile body.
Sealant: Use a high-quality exterior-grade caulking in the 5mm gap if a sealed moisture-proof finish is required.
Care: Periodically inspect the corners for debris buildup or gaps in the caulking. Clean with mild soap and water using a soft brush to maintain the finish.
