PLANE14 IN BC3
PLANE14 IN – Trimless Aluminium LED Profile for Plasterboard Lighting
PLANE14 IN BC3 by TOPMET Light is an architectural aluminium LED profile designed for seamless integration between two plasterboard panels. Its trimless construction creates clean, uninterrupted lines of light, making it suitable for modern residential, commercial and hospitality interiors.
Compatible with LED strips up to 14 mm wide, PLANE14 IN can be used for both general and decorative lighting, depending on the selected light source and diffuser.
Concealed Mounting for a Minimalist Finish
The PLANE14 IN plaster-in LED profile features mounting flanges positioned behind the plasterboard. The profile is secured by driving screws through the board into the concealed flanges, reducing the amount of filler required during finishing.
Once the surface has been filled and painted, only the diffuser remains visible, creating a discreet lighting feature integrated into the surrounding architecture.
PLANE14 IN is designed for installation between two plasterboard panels, while the related PLANE14 SIDE profile is intended for installation along the edge of a single panel.
When combined with a 120 LEDs/m strip and an opal diffuser, PLANE14 IN can produce a smooth, continuous-looking line of light with reduced visibility of individual LED points.
Compatible Diffusers and Accessories
PLANE14 IN supports two system diffuser types:
- B slide-in diffuser – available in transparent, frosted and opal versions.
C3 click-in diffuser – available in transparent, opal and black versions.
The B diffuser is compatible with the integrated Slick groove, allowing it to be clicked into place as an alternative to sliding it along the profile.
Dedicated PLANE14 end caps with cable holes are also available. These accessories are shared with the PLANE14 SIDE profile, simplifying component selection across the product family.
PLANE14 IN comes in three finishes: raw aluminium, anodised and white painted RAL 9003, with lengths of 1000, 2000, 3000 and 4050 mm.
Combining concealed mounting, straightforward plasterboard finishing and versatile diffuser options, PLANE14 IN aluminium LED profile provides a practical solution for integrated architectural lighting.
