Our DWP05 Inner 12mm Width single flange LED plasterboard profile is great for making smooth, trimless lines of light on walls and ceilings. This aluminum extrusion is made to be plastered in, so the channel is hidden under the drywall for a clean, modern effect. Measuring 36.0mm wide and 11.3mm deep, the 12.2 mm inner channel perfectly fits LED strips up to 12mm wide. The unique single flange design allows you to plaster right up to the light opening for a flush surface finish. Made from durable 6063-T5 anodized aluminum, it ensures excellent heat dissipation and includes a frosted diffuser for a smooth line of light.
Why Choose This inner 12mm LED plasterboard profile?
- Seamless integration lighting: The aluminum profile that goes into the plaster hides fully, so there are no apparent borders.
- LED lights without dots: Use with high-density LED strips to get smooth, steady light.
- Strong and resistant to heat: The extruded aluminum channel acts as a heat sink to make the LEDs last longer.
- Simple to put together: Just screw it in or attach it to plasterboard, cover the flange with plaster, and paint. Next, put in the LED strip and snap on the diffuser.
- Minimalist look: Great for modern interiors that require a smooth, clean finish without big trims.
- Great for wall wash profile and cove lighting channel designs.
