Hz Dual is a screw-fixed acoustic system developed for installation on a batten system or directly onto solid substrates. The system combines high sound absorption with a smooth, seamless ceiling surface, finished with Hz Acoustic Plaster, creating a uniform architectural expression without visible joints, seams, or perforations.
Hz Dual has the same panel construction and acoustic performance as Hz Basic. The key difference is that the glass granulate board is pre-drilled, allowing the panels to be screw-fixed instead of glued. This makes the system particularly suitable for projects where mechanical fixing is required.
Best for: rooms with high acoustic requirements and mechanical fixing
Best for: rooms with increased need for sound control
Best for: sustainable projects requiring mechanical fixing
Best for: sustainable projects with very high acoustic requirements
Hz Dual is installed by screw-fixing the acoustic panels through the pre-drilled holes in the glass granulate board. This provides a stable and secure installation on a batten system or directly onto solid substrates where adhesive installation is not desirable or possible. The pre-drilled holes are subsequently covered with plugs, ensuring a uniform surface ready for finishing.
The system is suitable for both new-build and renovation projects where mechanical fixing is required in combination with a seamless ceiling surface. After installation, the panels are finished with Hz Acoustic Plaster, which covers the surface and creates the uniform final expression.
Hz Dual is used in projects where mechanical fixing is required, for example in larger developments, public institutions, and commercial projects—without compromising aesthetics or acoustic comfort.
Hz Dual acoustic panels feature pre-drilled holes in the glass granulate board, allowing the panels to be screw-fixed. This provides a robust and stable solution, particularly in projects where adhesive installation is not an option.
If you require a glued solution instead, please refer to Hz Basic – glued acoustic system for solid substrates.
The panel construction of Hz Dual corresponds to Hz Basic, ensuring identical acoustic performance. You achieve effective reduction of reverberation and noise levels – whether the panels are glued or screw-fixed.
After installation, Hz Dual is finished with Hz Acoustic Plaster, creating a smooth and uniform surface.
Both solutions are free from visible joints and can be tinted in most official NCS and RAL colors.
Hz Dual acoustic panels consist of either mineral wool or recycled textile fibres combined with a pre-treated glass granulate board. The surface is robust and allows for the integration of spotlights, lighting tracks, ventilation, and other technical installations directly into the ceiling.
The recycled variants are part of Hz Recycled: acoustic systems based on recycled materials.
Hz Dual is suitable for:
The system can be used in both dry and humid environments when correctly constructed.
Good acoustics improve both working conditions and overall wellbeing. Hz Dual effectively reduces reverberation and noise levels, creating a calm and comfortable sound environment.
At the same time, the architectural expression of the ceiling is preserved with a smooth, seamless finish that can be repaired, maintained, sanded, and transformed over time.
