The Tamlyn Aluminium External Corner (XT-EXC-SG) is designed for contractors and homeowners installing fibre cement cladding who require a durable, professional 90-degree finish. It serves as a structural transition piece that protects corner edges while enhancing the visual appeal of the building exterior. A critical requirement for successful installation is maintaining a 5mm gap between the cladding plank and the profile to ensure adequate water drainage.

Yes, it is designed for standard fibre cement cladding, but always verify your specific board thickness to ensure it fits comfortably within the trim channel.
No, the profile comes pre-finished in Agate Grey and is ready for immediate installation.
Yes, maintaining the 5mm gap is critical for allowing moisture to escape, preventing rot and potential damage to the cladding boards.
No, you must use a blade designed for aluminium or non-ferrous metals to ensure a clean cut and prevent binding.
Each profile is 3 metres long.
An optional caulking line can be applied for added protection and a clean aesthetic, but ensure it does not block the drainage path.
Check if the cut edge of the fibre cement board has burrs or rough edges and sand smooth; ensure the trim is installed perfectly plumb.
Verify that the mandatory 5mm clearance gap is present and that no sealant is blocking the bottom of the profile channel.
To install, measure the height of the corner and cut the aluminium profile to length using a hacksaw or mitre saw with a non-ferrous metal blade. Secure the profile directly to the framing or corner stud using corrosion-resistant fasteners. Ensure the fibre cement planks are installed with a 5mm spacing from the inner flange of the trim to permit drainage.
Regarding care, the aluminium surface is low-maintenance. Periodically inspect the corners during routine house washing. Clean with a soft cloth and mild soap and water to remove dirt or debris accumulation. Avoid abrasive scrubbers that may damage the Agate Grey finish.
