working with auralex mineral fiber

[aquaman]

Anyone worked with Auralex Mineral Fiber? I was thinking of buying some because it seems the best mix of price, effectiveness and ease of purchase. I hope to construct a small partition to record vocals in and cut down on wall reflections. I have read, I believe on the Auralex site, that it can work in place of foam but they don't say what it's like to work with. Any ideas?
Thanks.

i imagine it will just be like any other mineral wool product... it will most likely sag and will not support its own weight unless secured in a wood frame...
