Incorrect Installation

Correct Installation

1. Use Click PVC

For areas exposed to direct sunlight, use Click PVC in accordance with DUMA®’s recommended installation system.

Do not use Tracker, as it may compromise installation stability.

2. Maintain Proper Batten Spacing

Follow the recommended batten spacing:

✔ 30 cm for areas exposed to direct sunlight. ✔ 40 cm for areas not exposed to direct sunlight.

Proper spacing helps minimize the risk of sagging.

4. Ensure Profile Joints Are Positioned Above the Battens

When joining two profiles:

✔ Ensure both profile ends meet directly above a batten. ✔ Secure the Click PVC on both sides of the joint using screws.  

This method helps keep the joints strong and stable.
