Millboard Envello Shadow Line+ External Corner Profile - Salt Blue - 50mm x 50mm x 3050mm

Envello Shadow Line+ External Corner Profile - Salt Blue is a flexible polymer resin profile that measures 50x50x3050mm designed to finish off the external corners of a building when using Shadow Line boards. You can fix it in place using the perforated closure and 20mm screws. 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.
