Counter battens are narrower and shallower compared to standard battens, measuring 19mm in width and 38mm in depth. They are installed perpendicular to the regular battens and serve multiple functions, including creating an air gap between the roofing material and the underlayment, improving ventilation, and providing additional support for the roof covering.

Features:

1. Ventilation Enhancement: Installed above the primary battens, counter battens help promote air circulation underneath the roofing material, reducing moisture buildup and helping regulate temperatures.
2. Dimensional Accuracy: Cut precisely to 19mm width and 38mm depth, ensuring compatibility and alignment with the primary battens to provide stable support.
3. Material Durability: Manufactured from high-quality timber or treated wood, ensuring durability and resistance against weather elements for extended use.
4. Secondary Support: They act as a secondary support structure for the roof covering, reinforcing the primary battens and contributing to the overall structural integrity.
