Product Information
Full details
The Aluminium Top Vent Strip (25mm) is an essential component for professional installers and DIY builders working with fibre cement cladding systems, providing critical ventilation to prevent moisture build-up behind exterior walls. It excels at maintaining continuous airflow and acting as a physical barrier against pests and debris, though users should ensure their specific cladding thickness matches the 25mm profile requirement to guarantee a flush finish.

FAQs
Can I use this for wood siding?
This product is engineered specifically for fibre cement cladding systems; check with your siding manufacturer for compatibility with other materials.
Is the 25mm size adjustable?
No, the profile is fixed. It is intended for systems where a 25mm gap is specified.
Does it need to be painted?
Aluminium is naturally corrosion-resistant, but it can be painted to match your siding color if desired using an appropriate metal primer and exterior-grade paint.
How do I cut the aluminium to size?
You can use standard tin snips or a metal-cutting chop saw with an aluminium-specific blade.
What is the primary purpose of this strip?
It serves as a ventilation bridge, allowing air to escape from the cladding cavity while preventing pests and debris from entering.
Troubleshooting
Strip does not sit flush against the cladding.
Check for underlying debris between the cladding and the strip; remove any fasteners that may be preventing a flat contact surface.
Airflow seems restricted.
Verify that the ventilation holes have not been accidentally blocked by flashing, trim, or excessive paint application during final finishing.
Pros and Cons
Pros
- Prevents structural damage caused by trapped moisture
- High-grade corrosion-resistant aluminium material
- Provides a clean, professional finish to cladding edges
- Simple, intuitive installation process
- Effective at excluding common household pests
Cons
- Specific to 25mm cavity requirements
- Aluminium can be sharp when cut; requires gloves
- Must be installed level to ensure consistent ventilation
Setup, Compatibility & Care
To install, ensure the cladding is cut to the appropriate length. Secure the strip along the top edge of the cladding panel, ensuring it is firmly fastened through the pre-drilled flange areas. Ensure there is no obstruction at the vent holes.
Compatibility: This strip is designed for systems utilizing a 25mm gap.
Care: Periodically inspect the vents during annual home maintenance to ensure the holes remain clear of paint or debris. If the strip becomes clogged with exterior paint or heavy dust buildup, gently brush it clean with a soft-bristled brush to maintain airflow.
