Test thermal and acoustic options in-house while the design is still open. When the project needs final verification, your consultant starts from a clearer assembly.
Test as many wall options as you need before you commit to one.
Every result comes from the same deterministic engine, whether you run it once or fifty times.
See the plansCreate the assembly from individual layers, materials and thicknesses.
Get U-value, Rw, C, Ctr and a dew-point check as you build.
Test alternative materials or thicknesses in the current assembly before you commit to the specification.
Generate a professional PDF report ready for your project file.
No specialist software. Runs in your browser.
No account required.
U-value, Rw and a dew-point check, calculated as you finish the layer stack.
No account required.
Test different assembly configurations and see how changes in materials and thicknesses affect thermal and acoustic performance.
Choose the solution based on calculated performance, not on the first layer stack you happen to try.
No account required.
Generate a professional calculation report for the selected assembly and keep the result with your project's technical documentation.
No account required.
Test assembly options before the client meeting, not after.
Spot dew-point risk or a weak acoustic layer early, before it reaches the site.
Run quick Rw checks on early options, then spend your time on the detailed work.
See the calculated values of an assembly before you order materials.
Show specifiers exactly how your product performs in a full assembly, not just in isolation.

Early-access pricing is currently available while ThermAcoustic PRO continues to expand.
Architects, building engineers, acoustic specialists, contractors and building-material manufacturers who need to calculate or document the performance of a building element.
The U-value with a steady-state dew-point check, airborne sound insulation (Rw, C, Ctr) for the same wall assembly. Roofs, floors and impact sound (Ln,w) are coming soon.
Yes. Free has no time limit and no account is needed. It uses the common material database, and PDF exports are watermarked and limited to 3 per day.
Yes. Edit the layers, materials and thicknesses and the results update. Professional and Business plans can also save and reload assemblies.
Yes. Business users can create custom materials and use them in their assemblies. Free and Professional accounts calculate from the built-in material database.
Yes. Saving and reloading calculations is available with Professional and Business.
Yes. Every plan includes PDF export. The Free plan is watermarked (3/day); Professional and Business include watermark-free PDF reports, subject to the applicable plan limits.
The generated report is designed to provide clear supporting calculation documentation for the selected assembly. Whether it is sufficient for a specific project, authority or contractual requirement depends on the applicable project requirements.
No specialist software - ThermAcoustic PRO runs in the browser. It is designed for technically informed building professionals; a basic understanding of construction assemblies and building performance is recommended.
You can cancel at any time through the billing portal. Cancellation takes effect at the end of the current billing period, and there are no refunds for partial periods.
