Hz FLEX – FLEXIBLE ACOUSTIC SYSTEM FOR CURVED CEILINGS

Flexible acoustic panels for curved ceilings – low build-up

Hz Flex is an acoustic system based on a flexible foam panel, glued directly onto curved ceilings where flat acoustic panels cannot follow the surface. The panel is finished with reinforcement mesh and Hz Acoustic Plaster 03, so the result is a homogeneous, seamless acoustic ceiling whatever the curvature. At only 20 mm thick, Hz Flex suits projects with limited ceiling height or listed-building requirements.

INSTALLATION GUIDE

How to install Hz Flex acoustic panels

Preparing the substrate

The substrate must be clean and free of loose particles. Unlike Hz Basic and Hz Dual, Hz Flex does not require a level substrate.

Gluing the panels

The foam panels are glued onto the substrate and shaped to the ceiling’s geometry.

Acoustic plaster as the finish

Hz Acoustic Plaster 03 covers the whole surface. The ceiling is homogeneous and white.

Technical integrations

Spotlights, lighting and curtain tracks are integrated during installation.

THE DECISIVE FINISH

Hz Acoustic Plaster – the seamless finish

Hz Acoustic Plaster 03 ties Hz Flex together. It is applied to the reinforced foam layer and is acoustically transparent; sound passes freely through to the foam panel.

The surface is sanded smooth and homogeneous – also on curved surfaces, where traditional acoustic panels cannot follow the substrate. The result is an acoustic ceiling that looks like an ordinary plastered ceiling, whatever the shape behind it.

Like the rest of Hz Acoustic’s systems, Hz Acoustic Plaster 03 can be maintained, repaired locally and sanded again, so the ceiling keeps its even appearance for years.

FAQ

Frequently asked questions about Hz Flex acoustic panels

Do you have a question that is not answered below?
See our general FAQ or contact us directly.

Yes, that is what the system is for. The flexible Hz Flex foam panels adapt to convex, concave and double-curved surfaces, where flat acoustic panels such as Hz Basic cannot follow the substrate in the same way.

Hz Basic uses rigid mineral wool panels for level substrates. Hz Flex uses flexible foam that can be shaped to curved surfaces, and has a lower build-up height (20 mm against Hz Basic’s 29-49 mm).

No, Hz Flex is used exclusively with Hz Acoustic Plaster 03. If you want the textured finish (Hz Acoustic Plaster 09), we recommend Hz Basic.

Yes, particularly on projects where the aim is to preserve ceiling height and any special details such as beams or cornices. We recommend Hz Basic, Hz Dual or Hz Plus where ceiling height allows, as these systems give a better acoustic effect.

Yes. One of the big advantages of Hz Acoustic Plaster 03 is local repair. Damage can be repaired locally, and the ceiling can even be transformed completely in a different color. Read more in our general FAQ.

PROJECTS

Hz Flex in practice

Hz Flex is chosen on projects where the shape of the ceiling, or the wish to preserve ceiling height, has set the terms – from listed buildings with exposed beams to modern apartments with concrete ceilings and rooms with curved, organic forms. Below is a selection of projects where flexible acoustic panels have created a seamless acoustic ceiling whatever the substrate.
