Insulation question

I just wanted to know what type of insulation is being used for these bass traps??? http://www.johnlsayers.com/HR/index1.htm Im thinking of building some in the near future and wanted to get all of the materials together....

Aloha and welcome to the forum, Mr Layz! Any chance you could please:

Edit your profile to include your location. This is very important, because this is a worldwide resource, and as such, material costs and availability vary widely. For example, masonry is cheaper than gypsum in some parts of the globe, whereas it's the exact opposite in other regions.

You'll probably get more of a response by doing so and this will really come in handy two or three posts down the road. It's also part of the forum guidelines: http://www.johnlsayers.com/phpBB2/viewtopic.php?t=3231 Thanks! :wink: Regarding your question; I was given this direction:

What you need to ask for is either rigid fiberglass, such as Owens Corning 703 (un-faced) or rockwool, mineral wool, somewhere between 2 to 4 pounds per cubic foot density; Johns Manville and Knauf also make similar products. Steve (Knightfly)

Hope this helps, Aloha 8)

Okay that does help because I didnt know if it was something like the pink insulation like you find in houses or what, and I will change my profile... Thanks

another option that performs quite well at a very good price is Ultratouch Acoustic Cotton. The specsfor this product show that it is provides pretty flat absorption to under 100Hz. If you can find a local distributorso that you don't have to pay shipping, the cost isn't much more than normal fluffy fiberglass.

Thanks for the input, im going to call a few places I found with the locator on that site and see how much it would cost.... Good looking out
