Planning aids

Our planning tools for your success

Finalise your construction project with the help of our tools for calculating reverberation time and determining accurate quantities! Please do not hesitate to contact our team of experts if you have any questions. We’re looking forward to your enquiry!

Quantity determination

We would be happy to help you calculate
your requirements with our quantity determination tool.

The following systems are covered by the calculator: S 3, S 3 cliq, S 3a, S 3a cliq, S 15 cliq, S 15a cliq, S 15b, S 19. The program is designed for OWAcoustic mineral tiles with module 600 x 600 mm and 625 x 625 mm or
1200 x 600 mm and 1250 x 625. Please note that the calculated values are non-binding approximations only and that deviations can occur in practice.

Reverberation time calculation

In recent years, sensitivity regarding the acoustic design of rooms has increased significantly. It is therefore important to determine the necessary product properties early on in project planning.

Plan with the OWA room acoustics calculator

When you need to select the right OWA ceiling tiles or OWA wall absorbers, our online tool is available for initial arithmetical estimations of the reverberation time. You can use this calculator to check whether the architectural acoustics in the room you are planning meet the relevant requirements.

Visualise your project with BIM/Revit

To take a virtual tour of a property even before construction starts and to get an impression of each element that is as realistic as possible, can be achieved using BIM. We offer a product library here compatible with Autodesk Revit.
