INSUL (v10.0.8)
Architects and acousticians have probably had to calculate sound insulation for walls, floors, and ceilings. Manual estimates can often be far from the real result. Well, INSUL v10.0.8 from Marshall Day Acoustics can help with that. It predicts sound insulation, including STC and Rw values, in minutes. You can download the app through this article. 🔥
Version 10.0.8 is the latest update, released in July 2026. There aren’t many changes, though.
Using it is actually simple. Just select materials from the dropdown, arrange the construction, and the results appear right away. No need to tear down a wall to see how it performs.
What I like most is that each construction is shown as you work. There’s also a 1/3-octave transmission-loss graph. So you can compare several designs at once and see which one insulates best. INSUL is usually used alongside SketchUp 2026 (Windows) after designing a house.
But for architects, I think this tool is worth learning. It could become an added selling point, right?
