Found national chain sells 703 rigid fiberglass

[ap]

It's called Specialty Products and Insulation Company. They have stores in CA, OR, WA, etc., but are mostly concentrated in the south.

woo hoo, just picked some 703 up in columbus. thanks man, they are not in the phone book.

[mixsit]

Thanks AP.

[Ethan Winer]

Fabulous AP, thanks very much. This will help a lot of people!

Watch how quickly I propogate this around the other audio newsgroups and web forums...

Yahoo.

Finally a supplier in Idaho.

[tomleblanc]

how much do they charge? Since they're national I figure it'd be relatively constant from store to store. For those of you who've already bought it from SPI, how much did it cost?

[dejacky]

yeah, what are their prices? And can't I get this stuff at my local Lowes or Home Depot?

And can't I get this stuff at my local Lowes or Home Depot?

-LOL!

If I remeber correctly, the 703 type was around $.63/sqrft for the 1" and $.92 for the 2". I think they have to special order 705- can't remember anything about the price.

[dejacky]

-LOL!

is that sarcasm insinuating a NO?

I am planning on picking up some 703 and creating the fabric covered panels.

Anyone know what type of fabric that would enhace the soundproofing qualities of the 703....Cotton vs. Wool vs. Nylon..etc

[knightfly]

Dejacky, LOL has two meanings in "net-speak" - either Lots Of Luck, or Laughing Out Loud

In this case, either would apply. The HD's and Lowes I've been in have almost NOTHING that's useful in acoustic treatment - most of their insulation materials are one type or another of Closed Cell foam, which is totally useless in acoustic treatment, because absorption works by air entering the absorption material and experiencing friction losses as it passes through the fibers of the material. The thicker and denser the material (up to a point) the better it works. Closed Cell means that no air can pass, so no absorption happens acoustically.

Standard fiberglass insulation batts do some good, but are nowhere near as dense as the compressed, semi-rigid fiberglass such as Owens Corning's 700 series; Knauf, Johns Manville, and Insulco also offer similar products in various parts of the world, but NONE of them are offered to home-owner types, so aren't available in that type of store in most cases.

This is the first "chain" type offering I've seen, and I've been moderating at two different sites for over a year. Everyone else has had to check the local yellow pages for commercial insulation contractors and BEG them to sell in smaller than truckload quantities.

AP has done us all a HUUUUGE favor by posting this - Ethan and I have linked to it on our other "haunts" to make sure everyone sees it - Thanks, AP, we all owe you... Steve

I don't think I can afford that fabric I have a big area to cover. I was thinking wool mainly because it is pretty fire resistant and I can get tons for real cheap. I am just not sure how well it will work compared to other materials.

[ob]

I saw somewhere on the net that a guy used garden fabric/weed barrier. Don't know how well that works.

With the fabric, you are trying to accomplish a couple things: Keeping the fiberglass fibers in, and not putting a reflective surface on your fiberglass, which will reduce your absorption results. When you say wool, are you talking about burlap? Or more of a solid sheet?

I called the atlanta dealer and this is what I was told for pricing on the 703


0.68/sq foot 1"
1.05/sq foot 2"

sheets are 4'x2' so each sheet is 8 sq feet. So the 1" is 5.44 per sheet and the 2" is 8.40 per sheet. I am pretty sure these prices are the same throughout the company. So I hope that helps! Good luck to everyone and happy sound treating!

[foreverdown]

someone has talked about burlap to cover these... any suggestions on where to get that in a stylish color? haha grey would do fine... or black or actually color doesn't matter at all. Just as long as it didn't once house potatoes.

[fucanay]

I called the SF location today and they want $1.80 sq/ft for 2" and $1.55 for 1". I guess the prices do vary quite a bit.

[notbradsohner]

psh, just in your case................................everything is more expensive in cali.

[dejacky]

Still,
these prices are not bad at all considering buying pre-made traps costs considerably more... right?

[Randy5235]

bump! this should stay close to the top maybe a sticky?

[imissthewar]

I live in Iowa, do these people ship?

[dejacky]

Which type of cheaply-priced fiberglass material is best suited for "sound proofing" a room in a house so that it blocks loud noises like Bass drum on drumsets and bass guitars so one doesn't annoy neighbors in nearby houses?

[pdlstl]

I bought 2" Johns-Manville rigid fiberglass. Same thing as 703 only specs out slightly better.

To cover, I bought inexpensive un-bleached muslin. My Auralex is charcoal/burgandy. I found a lady in Arizona who is cutting and tie-dyeing my muslin. Instead of the typical "round" tie-dye, she's doing it in "stripes". I think it's going to look nice.

Just my 2¢...

[dejacky]

pdlstl link please to what you specifically got form them?

No need to go to that extreme. Simple muslin or wool would work just as well. If you wanna increase high freq diffusion, put painter's plastic over the fiberglass before you cover with fabric.
