A decorative and acoustically effective suspended ceiling and wall panel for use in interior spaces as well as roofed outdoor areas that are not directly exposed to environmental influences such as rain or pollutants.

HERADESIGN® Superfine Alpha+ provides a high sound absorption performance made possible by the innovative combination of a wood wool acoustic board with a special a non-woven acoustic fleece laminated on to the back of the panel.

Features and benefits:

• Homogeneous wood wool panels with acoustic fleece.
• Highest absorption (class A) without mineral wool insulation material.
• Less obstruction in the ceiling void making installation, maintenance, disassembly and recycling easier.
• The sound absorption performance is increased compared to a standard panel – up to class A without increasing the thickness.
• Available in 15 mm, 25 mm and 35 mm thickness and a wide range of edge details.

HERADESIGN® Alpha+ is the new product line within the successful range of wood wool acoustic panels from Knauf Ceiling Solutions. In addition to the existing product lines, the fleece-laminated HERADESIGN® Alpha+ offers the proverbial plus in acoustic efficiency, effectiveness, ecology and design options.

HERADESIGN® Alpha+ stands for highly absorbing performance properties, made possible by an innovative composite construction of wood wool acoustic panels and reverse-side laminated acoustic fleece. Thus, with HERADESIGN® Alpha+, architects and planners have at their disposal an alternative that is increasingly favoured by the market and consequential in terms of ecological building compared to other composite constructions and replaces the classic acoustic pads. 

The change from a two-layer product with a mineral wool layer to  a homogeneous product with an acoustic fleece layer achieves and ensures at least double the loading volume when  transporting the panels by truck or container, resulting in a significant reduction of CO₂ emissions.

The fleece for lamination of wood wool, corresponds with  customers’ ever increasing requirements and demands for consistent use of natural materials in composite construction.

• The fleece lamination improves the panel’s acoustic properties  without change to the existing, standard thickness, 15mm, 25mm and 35mm.
• The panel’s new design construction facilitates the choice among all edge finishes and systems.
• Ball impact resistant installation can be guaranteed in accordance with DIN 18 032 / part 3 resp. class 1A as to EN 13964  attachment D.
• Alpha+ makes possible constructions with the highest absorption, class A, without the use of inorganic fibre insulation materials. 
• The necessity for foil packaging of mineral wool for trickle protection is not required.
• The wood wool acoustic panels can be installed in one go which saves time and cost. The material can be installed in a  lengthwise as well as a crosswise traversing direction.
• Cavity remains free of loose acoustic layers, therefore installations are freely accessible.
• The flexible design structure offers advantages during disassembly.
• The flexible design simplifies the disposal or recycling.
