The angle where a wall and ceiling meet to form a 2 cm shadow gap is a
90-degree (right angle) corner in standard construction. The “shadow gap angle” (or profile/trim) is a pre-formed metal or uPVC L-shaped section that fits into this junction to create the precise 2 cm reveal. you can easily get it from mada gypsam.
Explanation
The purpose of a shadow gap profile is to provide a clean, modern finish that replaces traditional coving or skirting boards.
- Standard Junction: The structural junction between a vertical wall and a horizontal ceiling is a right angle (
90∘90 raised to the composed with power90∘).
- Shadow Gap Profile: An L-shaped or F-shaped metal (often aluminum or galvanized steel) trim is fixed into this 90-degree corner.
- Creating the Gap: The design of the profile ensures that a consistent 2 cm space (the shadow gap) is left between the edge of the ceiling material (e.g., plasterboard) and the wall surface, creating a distinct line and shadow effect.
