They used to advertise this as Ultratouch denim. Don't know why they changed the description to natural.

You can order the Ultra Touch in small rolls from Home Depot. You have to peel the foil off the back - easy. The thicker stuff comes in very large batts.

I suspect a different supplier. Ultra Touch is a brand name.

OP asked for 1/2". HD sells 2.5". It's the only source of 1/2" I know of. Works GREAT for lining inside of compression drivers like JBL two inchers. I lined the entire back pots on mine with this stuff, to a great improvement in fidelity. I don't think you could get a better improvement for the money spent.

They no longer call it denim or cotton, either. In any event, I had great results with it.

The Ultratouch radiant barrier is 3/8 w/ foil back. The foil can be peeled off. I'm pretty sure that's what Pano mentioned.

Oh. I see. But while it would be easy to peel the foil off, in my application, I couldn't afford the stray fibers lifting off the base matt (due to tearing off the backing) interfering with the diaphrams. The source I cited had a smooth surface.

For base cabinets, I used the HD 2.5 inch stuff. No need to tear off backing.

Yeah, that's the stuff. I can understand not wanting to disturb the fibers.
Could you leave the foil on the back and place it against the back cap?

Wasn't there a thread somewhere else here in DIY ? Where ubiquitous F'glass House Insulation was claimed to be pretty well every bit as sonically effective, as the shredded clothes/cotton stuff from Home Depot? Only a bit unpleasant to deal with, being the basic detractor.
Nothing really changes does It ?
