Last time I bought it was just shy of R80/ 25mm sheet...that was many moons ago.

I paid around R1700 for 10 x 50mm panels (including delivery)about 2 years ago

Rather diy tube traps than flat panels

Isotherm is not too bad actually, I just did my entire listening room floor to ceiling with acoustic panels with 50mm Isotherm.

For HF reflections it certainly did the trick.

Isotherm needs to be placed far from a wall for usable results and then preferably with a membrane or perf sheet.

To be sure, have you modeled the sabins of the absorption to get to where you want to be? It's somewhat rare to need specific HF/MF absorption that doesn't also extend a bit lower.

You only need to do a third of the surfaces, making sure first reflections are covered. Too much and it sounds like the inside of a vacuum.
