Full details

This Tamlyn Aluminium Vertical Trim (XT-VERT-MB) is designed for professional contractors and DIY enthusiasts installing fibre cement cladding panels who need a clean, architectural finish. Its primary benefit is providing a secure, seamless connection point for panels that works in both vertical and horizontal orientations, though installers must be prepared to maintain a strict 5mm clearance to ensure proper system performance.

FAQs

Can I use this trim with wood siding?

This trim is specifically designed for fibre cement cladding systems. While it may physically fit other materials, it is optimized for the dimensions and movement characteristics of fibre cement.

Is the black finish paintable?

The high-quality aluminium finish is designed to be durable as-is, but if you choose to paint it, ensure you use a primer suitable for aluminium surfaces.

Does the 5mm gap apply to all climates?

Yes, the 5mm clearance is a standard requirement to accommodate the thermal expansion and contraction cycles of fibre cement materials.

How do I cut the 3-meter trim?

Use a standard chop saw equipped with a fine-tooth blade designed for cutting non-ferrous metals like aluminium.

Do I have to use caulk?

While the caulk is optional, it is highly recommended in areas with heavy rainfall to ensure the cladding system remains fully weather-resistant.

Troubleshooting

Trim feels loose after installation

Ensure that the cladding planks are securely fastened to the studs and that the 5mm gap is not exceeded, which could lead to play within the profile.

Water pooling near the trim

Verify that your caulking line is intact and that there are no obstructions in the channel preventing water from flowing downward.

Difficulty inserting cladding into the channel

Check the cladding board edge for factory defects or debris; ensure the 5mm clearance requirement is being strictly observed.

Pros and Cons

Pros

  • High-quality, corrosion-resistant aluminium material
  • Dual-use design for vertical or horizontal application
  • Creates a professional, clean transition between panels
  • Long 3-meter length reduces need for multiple segments

Cons

  • Requires precise 5mm clearance measurement
  • Installation must be accurate to ensure proper water drainage
  • Optional caulking adds an extra step to the installation process

Setup, Compatibility & Care

To ensure proper installation, follow these guidelines:

  1. Clearance: You must maintain a minimum 5mm gap between the edge of the fibre cement planks and the internal face of the profile. This allows for thermal expansion and proper movement.
  2. Drainage: For maximum weather protection, apply a high-quality, paintable exterior sealant in an optional caulking line to ensure that any water running down the cladding is directed away from the wall substrate.
  3. Cutting: Use a metal-cutting blade on a miter saw to trim the 3-meter profiles to size to ensure a clean, burr-free edge.
  4. Maintenance: Periodically inspect the caulk line for cracks or degradation. The aluminium itself can be cleaned using a mild soap and water solution to remove dirt or debris buildup.
