Rockwool

Hi. I'm about to make some acoustic panels for my home studio but am confused about the type of Rockwool I should use. I thought I'd come here and hopefully get some advice from you lovely people.

I'm thinking of either of these:

https://www.wickes.co.uk/Rockwool-S...Jq6sfjgWrQ2XE59rObMaAmG6EALw_wcB&gclsrc=aw.ds

or: https://www.ikoustic.co.uk/products/acoustic-underlay/rockwool-acoustic-mineral-wool-rw3-100mm-60kgm³

Which would be the best as acoustic treatment or should I be looking for something else?

Thanks for any advice - it'll be much appreciated.

Cheers

Scott
 
From what I can see on those pages, they appear to be identical products - at least as far as sound insulation and dimension goes. One is a 6-pack, the other a 4-pack, hence the price difference.
 
The Wickes product looks like it'll do the job.
Have you looked on Studiospares.com? They changed hands recently, but they used to offer acoustic rockwool slabs.
Probably the same product as Wickes.
 
My last project studio during covid used the wicked product, but this onehttps://www.wickes.co.uk/Rockwool-Sound-Insulation-Slab---50-x-600mm-x-1-2m/p/148841 this is the 50mm version. 4” is useful when you want that thickness, but cutting it neatly to 2” if you need a hang on wall panel is less wasteful. The thicker stuff is good for deep cavities of course, and quicker than stacking two layers. Product wise, it’s exactly the same products that I’ve used many times before but a pretty decent price, which wicked are not for some things. My local wickes never had that much in stock.

there are lots of products but rock wool is probably the most versatile. I still like foam for absorption of annoying HF but it runs out of steam quickly performance wise, but it’s still useful. Rockwell is also easy to shape but very crumbly.
 
Thanks for the replies folks - much appreciated. I think I’ll go for the Wickes stuff then.
Thanks again:)
 
The pink fluffy stuff performs better for absorption than rockwool and it's cheaper. You only have to run the lengths vertically in frames.

Just sayin...

I’d like to see the specs on that. It takes mass to absorb bass frequencies and unless you have some way of compressing the “pink fluffy stuff” it’s going to take a crapload more of it, i.e., much thicker panels, for the same absorption. (I’m assuming the Wickes product is equivalent to the Rockwool (née Roxul) brand available in NA.)

From my understanding it takes mass to isolate sound waves, not to absorb them. Rockwool can be somewhat reflective at certain frequencies...

I myself have like 20 rockwool panels and a whole ceiling in my drum room filled with it. I took the advice on forums for those treatments over the last decade. Recent testing has found more efficient methods. Not that they are not effective and worth using, but there are better ways.

I now am remodeling my studio and treatments. Likely a $18,000 project. The only real repurpose for my existing rockwool is to stop resonance in a double wall between control room and an isolation room. I have hired John Brandt to consult and design my control room as well as his advice on my isolation rooms. All of my new treatments in my CAD drawings include wide-band absorption, limp bag absorbers, membrane absorbers, a cloud and diffusors. None of it includes any rockwool.

I would suggest taking the time to visit his site to get detailed information from his resources page. He is very accessible to respond to direct questions as well, without having to pay him. Here is a link to JH Brandt's website. I am also posting an invite link to his Discord forum. Always best to have the most knowledge you can find before spending your $$!

Cheers!

When I was researching this Jimmy, I came across companies who were specialising in sound treatment for lots of different situations and buildings especially. A lot of them used perforated materials to treat the sound instead of and with some kind of absorbing material.

Sounds very interesting! Perforated materials instead? That seems odd to me but hey, if it tests out to be true...

Companies that specialize in 'selling' acoustical treatment, or design appropriate treatments for small spaces- or for large buildings? There is a huge difference between a small room and a hall. Aslo a huge diference in the purpose any room is being used for. I may have misunderstood your point...



Egg cartons are still used by people that have not access to modern techniques. Not everyone is up to date with the latest options and test results. I have learned more about acoustic treatment in the last two years than I did the decade before. I only share what I find to be the most useful now.

Well I thought, have the perforated material at the front or face of an acoustic panel, so that you disintegrate the sound waves before they hit the absorbing material. Be a lot more effective I thought. I did see something similar by one company, so not the only one it appears. But in my case the perforated material apparently is very expensive and requires a quantity purchase.

Here is one version......... Thomann

You may find this of interest in acoustic panels. They explain if you read down the page............. UK Company

Esmono booths have a perforated inner steel wall, over some black fabric, over the rockwool. Then a solid outer steel wall.
 
From 3 decades of recording and listening to any advice I have found on internet as well as direct contact with some 'better than I had' studios. have learned a shit ton. More in the last couple years have made clear to me what works with tried and true methods and testing.

Bottom line that I have learned is that simple panels and bass traps will work to a degree. We can sense the room is better. What is not addressed by most is actually testing what is wrong with the room to begin with. Adding simple panels may improve what you hear. Anything is better than nothing, but knowing what actually works by testing and knowing what your particular room is doing to fuck you, is most important.

In my case with my control room, was that the room modes were making it impossible to get anything accurate below 80hz. I am changing my room size and treating to make this a non issue.

Calculate room modes first with the dimensions or your room. JH Brandt has a room mode calculator free to use. From there you can know what you need in your particular space. Just throwing up haphazard panels get you something. But what is that something? We do not know without first understanding why...
 
You are most likely correct Jimmy. But everybody may agree......the best music is from the past.

So whatever they used worked just fine apparently.
