Perforation designs
The secret to acoustic comfort with Knauf DANOLINE ceilings lies in the perforation. By punching holes in a gypsumboard, we give the material an ability to absorb sound. And add an aesthetic character to the material, too. The different geometries of the perforation holes define the degree of sound absorption and sound diffusion.
Unity perforations
The series of Unity perforations extend to the edge of the tile. This means that the finished ceiling surfaces appears smooth and unified surface – thus the name Unity. The Unity series offers a range of perforation geometries to cater to your design specifications.
