I used rockwool.
I considered it, but fibreglass is just that much more efficient for the same thickness.
Do you think there is a market for these? I would be able to make them to custom sizes and fabric trim.
Not really, no. There are a number of companies and quite a few individuals doing them and no-one is really making a fortune from them. Thing is, when people start looking at them, they discover that they can make them themselves. The only real advantage you can offer over a DIY one is a professional looking product (e.g. Genesis acoustics offer them with art or photo prints on the fabric).
Your studio is looking good Alan. A nice big room... but also means more acoustic treatment hey!
Yup, but far fewer problems with standing waves, which tend to be the real issue. ?
I also have a tin roof and I installed Onduline on top of the iron.
Thanks - Looking into it now. Looks like a great alternative to zinc - waterproof, lightweight and higher STCs. I'll probably install straight to joists though, to avoid the possibility of creating a triple-leaf system between ceiling, zinc and Onduline. I'm also looking into Magnesium Oxide (MgO) ceiling boards, which seem to offer performance double the conventional gypsum boards for the same thickness. Fortunately, it's a quiet area, so I don't have to go too nuts. Basically I have to stop the noise of my neighbour's sheep. ?
1) Is that dean's body really that small?? I thought they were ES335 sized ???
Just fractionally wider than an LP. More like an ES339. ES335s are too big for me - I'm only little.
2) Is that a ridgeback? (Does he/she provide vocal accompaniment?) ?
Yup, and thankfully, no, he doesn't join in, but will often sit on my drumming feet or rest his chin on my arms while I'm trying to play in an attempt to get attention.
