I’ve been trying to get ahold for of Don from SDS to no avail and noticed today that his website was “down for maintenance”.

Well Don finally emailed me back:

“Chris,

I've retired and SDS will not be selling any more materials. Sorry. I'll refund your payment.”



Looks like the provider of the best CLD tiles out there has gone out of business.

Don’t mean to sidetrack the CLD dialogue

But has anyone figured out the Velcro Don was selling. I tried the 3m Dual Lock product (both 250/400 and 400/400 versions) but it doesn’t come close to the strength of the Velcro from SDS.
I was trying to figure out the same thing. Here is a older screenshot saying what type of Velcro works.

I found the same stuff here- https://www.itapestore.com/velcrotapehookloopacrylicadhesive.aspx

I ordered it, but haven't tried it yet

Can the lux liner pro work inside a door? It’s pretty heavy... but if you use the correct adhesive I think it can work?

Or is there a better product to use?

I found this forum and thread after going to SDS this weekend to place an order for a personal project. I've never ordered any of this type of product before, so unfortunately I don't have any experience for comparison. But, I like doing projects right the first time, regardless of cost, so SDS seemed like the right place to go. I'll be pausing my project until a general consensus is found regarding comparable alternatives. It seems to me that some of the products are easily replaced (MLV/CCF/HMF) but the CLD tiles and velcro were the best available on the net.

I'm hoping this thread can stay on topic and focused on finding comparable alternatives to SDS so we can press on with our projects. On that note, perhaps this for the velcro:
High-Heat Acrylic 3M Brand Hook & Loop (PSA)

Unfortunately I have nothing for comparison so there's no point in me purchasing it. If anybody is willing to sell me a few pieces of velcro and/or 1 CLD tile so I can have something for comparison, please PM me and I'll start purchasing possible alternatives for testing.

Thanks

RRWWS: So how did that Velcro compare?

I figured that but some people wouldn't be able to get that through their head.

What ever happened to SDS?

I actually met Don at his house way back in the day and we added all of his products on my old del sol. Such a great guy.

Don closed up shop/retired from the sound treatment industry.
I don't believe it was ever said out loud. Don stated that he retired.
I saved the materials lists for the Camry and Avalon from the SDS site before it went down. It doesn't look like this is available on the archive.org backup. Hopefully someone will find it useful
