3D BLACK XL is what the Perfosound-line planks are called that have a rough, rustic appearance. The XL version is the rougher-looking, bigger brother of the 3D BLACK version. The roughly brushed veneer really brings its appearance to life. A three-dimensional effect is created when the planks are finished in matt black. The structure of wider strips with corresponding grooves create a unique appearance. The holes behind the groove-pattern completely disappear in the black core. 3D BLACK XL is hardly recognizable as sound-absorbing plank. It’s equally fir for application on walls and ceilings. After mounting of the planks, they create one continuous pattern together. The grooves in the panel lead soundwaves to the back structure, where they are absorbed by mineral wool. The core of this panel is high-end MDF E1 and completely pitch-black.
