condensed fiberglass info/where to buy thread

[giraffe]

i'm trying to make this a one stop shop for fiberglass info, because wadeing through this crap sucks

feel free to add, but let's keep it as information heavy as possible.

Here you will find NRC ratings for just about any insulation or absorbtion product on the market... shows ratings for each thickness... thought this might help a few people out...

They've got a bunch of locations scattered across Maryland and Virginia. They were helpful, cheerful, and highly professional -- and that did not change when I told them I only wanted two packages of material.

Ottawa Fibre products, specifically the OFI-48 and OFI-64 (http://www.ofigroup.com/) are supposed to be extremely similar to the OC 700 series.

These OFI products are available through ISOFAB at several locations:

A good friend of mine works for Patene's which is a building suppy company here in Ontario. They dont rep Owens Corning, but they carry what he thinks is a similar product Roxul RXL40. A semi-rigid insulation which comes in 24x48" pieces of thickness 2, 3 or 4". Apparently their min. order would be one bag which contains 64, 48, or 32 sq.ft respectively. This is what I plan to buy when Im ready.

Seriously, I'm no expert, but the data clearly shows that rigid fiberglass and rockwool do a pretty darn good job absorbing down to the 125 to 150hz range. I'm not sure what you consider the "low mid and bass range," but rigid fiberglass clearly does more than "reduce the reflection of upper midrange and high frequencies." Sounds like you are describing the performance of foam.

On Ethan's site, he explains: "705-FRK that is four inches thick and spaced 16 inches away from the wall can be quite effective to frequencies below 125 Hz." He also has data showing that higher density provides better absorption at the lower frequencies.

Check out Table 1 on Ethan's site (it lists absoprtion coefficients):

http://www.ethanwiner.com/acoustics.html

Check out Page 2 on this website for rock wool absorption coefficients:

http://www.fibrexinsulations.com/pdf...uationFire.pdf

I do believe that sealed bass traps like those described (and manufactured) by Ethan provide absorption below 150hz, but stating that rigid fiberglass panels only absorb the upper-mid and high frequencies is just plain wrong.

Good idea. For rockwool in Canada, (or possibly elsewhere) see www.Roxul.com The Safe n' Sound product is the best.

This is the best overall solution!
the stuff is soundproof with just one sheet Comparable to over eight sheets of drywall.
this stuff has some special threads or something that convert sound to heat then there is a metal sheet laminated between the qypsum to stop the heat.
THX certified
check out the specs @ www.quietrockonline.com and don't forget to mention supertech I'm gonna need more!!!
thanks for the info on the doors too.


rock on

I am affiliated with the site. I hope this post is helpful to those of you looking for an easier way to get the materials you need.

helpful thread here: http://homerecording.com/bbs/showthread.php?t=147777

I purchased useful panels to hold the fiberglass from www.modularacoustics.com, then purchased Roxul Safe n Sound from Home Depot. Very affordable solution, and good guy to work with.

spi-co.com

Here's a clickable link...
SPI
P.S. Here's a map of their locations...


Cheers..

[emergencyexit]

SPI didn't make me buy in 12 packs. They were fully willing to break open packs and sell by single panels. I happened to have bought 20 anyway though.

Ben

Any price and thickness info would be awesome... Thanks

[giraffe]

i think 703 was about 1.15 a square foot?
many equivalent products are much cheaper.

1260 2" (51mm) A 6.0 pcf (96 kg/m3)
0.25 0.85 1.15 1.10 1.04 1.06 1.05

that's what i got, for about .60 cents a square foot

by comparison
703, plain 2" (51mm) on wall 3.0 pcf (48 kg/m3)
0.17 0.86 1.14 1.07 1.02 0.98 1.00

unfaced 703 is about twice as expensive.

An off-site, but parallel thread: http://www.musicplayer.com/cgi-bin/u...6;t=001246;p=1

[Kasey]

this is a marvelous thread... im having trouble finding the pricings for a lot of this insulation though.

[Kasey]

which is better from Roxul, AFB or Safe?? you keep saying "safe n' sound"..but im not seeing that

[bpape]

Either is fine. I prefer the RHT80 for bass control duties.

[Jonk]

Hey everybody,

My first post here. Lot's of good info concerning where to buy rigid fiberglass and rockwool.

I'm out in California, a couple hours away from S.F. so I checked the SPI there and they're prices seem pretty high. The 8 pcf 2" 2'X4' panels of Roxul are $.70 a square foot.

I mentioned that I'd heard about someone in Oklahoma (Scottgman) getting it for $.39 a square foot, and the guy said that's lower than they get it at cost.

Anyway, does anybody know of a good place to get Mineral Wool close to the Bay Area? I'd even be willing to pay more that .39 a sq. foot, but I think I can do better than .70. I need a lot of it.

At 125Hz it has an NRC of .97, and from 250Hz upwards its NRC is above 1.0. Also, this stuff is completely safe - it contains no dangerous fibers or particles and causes absolutley NO skin irritation whatsoever. It is 100% percent safe.
Not enough you say? Well, each natural fiber of UltraTouch is saturated with a natural fire retardant (borates) giving UltraTouch insulation a Class-A fire rating. UltraTouch also contains active mold inhibitors and acts as an excellent pest, mold and mildew inhibitor.

You can check this stuff out here:
UltraTouch

And here is a place you can order the stuff:
UltraTouch Prices

I have no idea what shipping would be like on this stuff, but if you go to the Bonded Logic website and click "Find a Distributor", just follow the instructions and you should be able to find a supplier in your area.


Just giving ya'll a heads up!

EDIT: Forgot to mention, in the prices link that I gave, the R-13 is a 3.5" thickness, and the R-19 is a 5.5" thickness.

stufffffffff

How many fiberglass panels do you think i can make for $50? I was gonna spend $100 but i had some unexpected bills to pay. I wanna get the fiberglass panels first, and then i wanna get some auralex foam.

(p.s. Giraffe you misspelled "where" in the title )

Do you think Safe n' Sound is best for panels?

i think i paid .60 cents a square foot for (hold on)

1260 2" (51mm) A 6.0 pcf (96 kg/m3) 0.25 0.85 1.15 1.10 1.04 1.06 1.05
(it's rockwool)
at http://www.spi-co.com/servicecenterdirectory.mv

and it only comes in 2*4 pannels so...
you do the math.
p.s. i do reccomend the 1260
