Aluminium shadow joint profile CR-8
8 mm shadow joint between two plasterboard panels on ceilings or walls — clean decorative lines and stable joint geometry.
The CR-8 aluminium profile creates a narrow shadow gap between plasterboard sheets in the plane of the ceiling or wall. This solution is used to create fine decorative lines that add depth to the surface and highlight modern interior architecture. An 8 mm joint is a popular detail for projects in minimalist, modern, and hi-tech styles.
