Stop waiting on an external consultant
to find out if your assembly meets the requirements.
Architects, engineers, construction companies, and building materials manufacturers use ThermAcoustic Pro to test thermal and acoustic performance in-house - the moment they need an answer, not on someone else's schedule.
Hiring an external expert
- Per-report fees add up fast across a project
- Days of turnaround for a single system
- One system tested per report
- Pay again for every revision
ThermAcoustic Pro - Business
- $79/month for up to 40 reports - under $2 each
- Results the moment you calculate
- Test unlimited system variations
- Revise and re-export at no extra cost
Test as many wall, roof, and floor systems as you need before you commit to one - no waiting, no per-report invoice.
Every result comes from the same validated engine - ±5% of lab-measured accuracy, whether you run it once or fifty times.

Build
Create the assembly from individual layers, materials and thicknesses.
Calculate
Get U-value, Rw, impact sound and condensation risk instantly.
Compare
Test alternative materials or thicknesses, compare up to 4 assemblies side by side - or calculate multiple project positions (POS1 wall, POS2 floor, POS3 roof) at once.
Document
Generate a professional PDF report ready for your project file.
No specialist software. Runs in your browser.
Build the assembly.
Get all the results instantly.
U-value, Rw, impact sound and condensation risk - calculated the moment you finish the layer stack.
- Thermal performance - U-value and condensation risk (Glaser method)
- Acoustic performance - Rw and impact sound, with C and Ctr correction terms
- No separate calculation pass - results update as you build
Compare
before you commit.
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 configuration you happen to test.
- Compare up to 4 assemblies side by side
- Test alternative materials and thicknesses for one assembly
- Calculate multiple positions of the same project at once - e.g. POS1 wall, POS2 floor, POS3 roof
- Evaluate thermal and acoustic results together
- Identify the assembly that best fits your project requirements
Once you have the right assembly,
document it.
Generate a professional calculation report for the selected assembly and keep the result with your project's technical documentation.
- Clear assembly description
- Calculated thermal and acoustic results
- Professional PDF report
- Ready to keep as supporting calculation documentation

Architects & Project Designers
Compare 4 assembly options before the client meeting - not after.
Building Engineers
Catch a condensation risk or Rw shortfall before it reaches the site, not after.
Acoustic Specialists
Run the routine Rw/Lnw checks in-house, and save consultancy time for the cases that need it.
Contractors
Confirm the assembly meets spec before you order materials - not after.
Building Material Manufacturers
Show specifiers exactly how your product performs in a full assembly, not just in isolation.
Built on validated acoustic engineering.
Not guesswork.
What makes the acoustic calculation reliable isn't the formula alone - it's the combination. Sound transmission loss is predicted using the mass-law and critical-frequency approach for simple partitions, and more refined models for multi-layer, lined, and composite constructions, built on EN ISO 12354-1 and EN ISO 12354-2 methodology. Those models are continually checked and adjusted against real laboratory measurements, which is what keeps the predictions accurate across a wide range of real-world wall, floor, and roof buildups.
Good to know: like any acoustic prediction tool, ThermAcoustic Pro is not a substitute for laboratory test data. Use it to compare options and lock in a design with confidence - then validate the final, certification-critical assembly against tested data.

Common questions.
Straight answers.
Who is ThermAcoustic PRO for?
Architects, building engineers, acoustic specialists, contractors and building-material manufacturers who need to calculate, compare or document the performance of building assemblies.
What can I calculate?
Thermal performance (U-value, R-value, condensation / vapour diffusion), airborne sound insulation (Rw, R'w) and impact sound (Lw, L'nw) - all from the same assembly.
Can I compare different assembly options?
Yes. You can build, modify and compare alternative assemblies - Professional and Business plans compare up to four side by side.
Can I use my own materials?
Yes. Business users can create custom materials and use them in their assemblies. Free and Professional accounts calculate from the built-in material database.
Can I save my calculations?
Yes. Saving and reloading calculations is available with Professional and Business.
Can I generate a report?
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.
Can the report be used as part of project documentation?
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.
Which standards and calculation methods does ThermAcoustic PRO use?
Thermal calculations follow EN ISO 6946. Acoustic calculations follow EN 12354 / EN ISO 12354-1 and 12354-2 (airborne and impact sound insulation), with single-number ratings derived per ISO 717-1 and ISO 717-2. Condensation analysis follows the Glaser method per EN 13788. These methods are checked and adjusted against real laboratory measurements, which is what keeps the predictions accurate and credible across real-world wall, floor, and roof buildups.
Do I need specialist software or engineering experience?
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.
What happens if I cancel my subscription?
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.
