The Tamlyn Aluminium Bottom Vent Strip (XT-BVS-38MM) is an essential component for professional contractors and DIY enthusiasts installing fibre cement cladding systems, providing critical ventilation and pest protection. By facilitating continuous airflow behind the cladding, it helps prevent moisture buildup and structural degradation, though users must strictly adhere to specific installation heights and ground clearances to ensure code compliance and long-term durability.

This model is specifically engineered for 38mm battens; using it with other sizes may compromise the fit and structural alignment.
If installation is less than 150mm from the ground, you must paint the rear of the bottom cladding plank to prevent moisture absorption.
No, it is constructed from aluminium, which is naturally corrosion-resistant, making it ideal for exterior cladding applications.
The 10mm gap is necessary to ensure air can freely enter the cavity behind the cladding, which is essential for the moisture management system to work.
Yes, the vent strip is designed to act as a physical barrier to prevent vermin and insects from entering the cavity while still allowing air passage.
Check the 10mm gap beneath the profile; ensure no sealant or debris has bridged the gap between the cladding and the strip.
Verify that the installation is at least 150mm from the ground and ensure the rear of the plank has been painted for moisture protection if near the terrain limit.
For proper setup, ensure your 38mm battens are securely fastened and leveled before mounting the vent strip. Align the profile flush with the base of the battens and secure it using corrosion-resistant fasteners compatible with aluminium. When installing, always maintain a minimum clearance of 50mm from horizontal surfaces like roofs or balconies to ensure the airflow path remains unobstructed. Maintenance is minimal: perform an annual visual inspection to ensure the mesh has not been clogged by dust or debris. If dirt buildup is noted, a light spray from a garden hose or gentle brushing is sufficient to restore full airflow efficiency.
