TOPPERFO® Bubble are acoustic panels with different hole diameters. Plasterboard ceilings with different hole sizes have been on the market for years. What is new and different with Topperfo® Bubble is that the panels can be dismantled individually and there are two different hole patterns. Topperfo® Bubble #2 with an αw value of 0.5 and Topperfo® Bubble#3 with an αw value of 0.7 with a thickness of 56mm. Both versions are available in all finishes, natural wood veneer, RAL/NCS varnish and melamine/laminate decors. Also available in all fire classes.
