Millboard Envello Board and Batten Square Corner Profile - Jarrah - 50mm x 50mm x 3050mm

Millboard Envello Board and Batten Square Corner Profile - Jarrah is a premium trim designed for modern cladding projects using Envello Board and Batten cladding to finish both internal and external corner connections, for both vertical and horizontal installations. These corner profiles will help conceal exposed corners and protect against insects or rodents entering through gaps in the cladding while allowing for airflow. It replicates the look and feel of real wood, but is 100% wood-free, resists fading, warping, and splintering, and free from the risks of rotting or attracting insects and pests like real wood or wood composite. Resilient Lastane layer chemically melded to the core refers to a durable outer surface that provides protection and resilience. Millboard cladding is UK-made, reflecting British craftsmanship, innovation, and quality.

Incorporate these profiles into architectural features such as window surrounds, door frames, or column wraps. They enhance the overall aesthetics and durability of these elements. If you’re installing wall panels or wainscoting indoors, these profiles can be used to create sharp corners and edges. They add a polished look to your interior spaces. These profiles can be used for accent walls, reception areas, or feature walls. They withstand wear and tear while maintaining a sophisticated appearance. The square corner trim provides protection to the edges of your cladding system. It shields the exposed edges from impact, moisture, and wear.
