I finally finished and installed my Ultratouch cloud over my drumkit.

Just built a 5'x6' frame out of 1x5's, attached chickenwire, stapled burlap over that, sprayed with FireStop, laid R19 in and mounted the whole thing on the ceiling above the kit.

No objective testing but its very noticeable how much clearer and crisper my cymbals and drums in general are in the overheads.

Have you used that on Ultratouch Cotton? I just don't believe it would work on ultratouch unless someone has actually used it on ultratouch.

Just Imagine trying to cut a dense 8" thick cottonball with strings and jean material mixed in. Everytime you hit a string or jean material you end up tearing all of the cotton around it.

Hello everyone, I've been lurking here for like ten years! Now I'm completing my studio build here in France and I'm using Isoa cotton insulation. I followed the manufacturers recomendation and used one of these to cut the insulation which I bought in 2 inch and also 8inch thickness:


It's a disc cutter with a 9" blade which I had already bought for house renovation. It works a treat and cuts really fast, no more frustrated hacking with a knife!

I've made 34" face corner chunks and am making 2 inch panel traps. I'll post up some pics when I get a chance.

Cheers

PS I think you'll find my absorber design rather novel ;)

Thank you for the tip Driller!

I used a regular circular saw with a plywood blade to cut my Ultratouch. It worked just fine. Pop a chaulk line on both sides, cut first side then turn over and cut again. Pull apart. The secret is to hold the saw over the stuff so it doesn't compress the insulation.

Driller, you saved me SO much work with that recommendation of a disc cutter. It worked so well!

Best $49 bucks I ever spent on a project, thanks!
