Can Ceiling tiles be used for bass Trap?

Hello, this is my first post on this forum, I just got a quick question, in my quest for Cheap/good materials to make acoustic traps I came across with this material: http://www.lowes.com/lowes/lkn?action=p ... lpage=none has anyone try to put a few of this together and make a trap? The material seems to be more dense than 703 or 705 and its cheaper, it comes in 5/8 thicknes, the plan its to put 3 tiles together frame them and wrap with fabric, Im I just wasting my time here? thank you..

Ceiling tile material is typically similar to 703/705 - usually a mineral fiber of moderate density. However, I would think that the tiles would be more expensive than if you just bought the raw FG or mineral fiber boards? Also, depending on how they're faced (on both sides) might affect (for good or bad) their performance as "bass traps". That aside, there'd be nothing wrong with making "bass traps" out of them. Strapping three of them together would give you almost 2". IMO and depending on where/how you plan to mount them in the room, you might consider at least 6 of them to get close to 4" thick.

Thank you for the reply in my area the 703/705 are about $99 for 6 pieces 24x48x2 but this title its $36 for 24x48x5/8, but there is some def. differences between the two, the 703/705 its lighter/a lot less dence, thats were my questions come in at, the 703 needs to 4''(according to all I have read in this forum) to be a Bass trap, well since the ceiling titles material its more dense can it be thinner? or does it still adhere to the same reflect/absorb diameters regarless of the density? The ceiling title has its disavantages, a mayor one its weith if I have to put 4-6 of them together I will be looking at around 6-8Lb were the 703 I will be looking at maybe 1lb. thank you again for the reply and for taking the time to read thru this crazy idea...

:) vegas4ever That's a strange link. When I enter it from Belgium, they ask for a ZIP code to direct me to a local store. :) I only saw a picture with 2 guys and 2 girls (looking good but not as bass trap I assume) So I just entered an arbitrary 5 digit number and got lucky. I have the feeling Jeff confused these tiles with other ones I assume. This are these cheap cardboard like feeling (poetic license) Armstrong tiles. I don't think that's a good choice for this purpose, no matter how many you combine. I never tested that, but know them (sold worldwide) and listen to my instincts now. Just stick to the known traditional materials. We do have here (and probably in US) ceiling tiles which should work perfectly, but not those ones.

Eric's thoughts on the matter are probably more accurate than mine. :oops: Now that I think about it, even the mineral fiber tiles at home improvement stores can often be of relatively low density. If you stack enough of them together, you might get some good low-end performance out of them. But at that point, you're probably better off spending your money on the raw materials - and, therefore, you can expect better performance for the $$...

thank you again.. just one more question, Im pretty sure this has been cover already but what about the owen cornings R-15 roll stuff? any good? Thats stuff its dirt cheap compare to the 703.

Rolled insulation (like the "pink stuff" or equivalent) typically has a density on the order of < 1 lb/ft³. This is inferior, in many respects, to something like 703/705 in terms of effectiveness for treating low-end problems. However, in thicknesses greater than 12", uncompressed, can be useful. If you want to compress it and use several layers, it will provide better performance, but then it becomes difficult to make it look like anything presentable. :? And, again, by time you get enough to compress and layer, you're probably getting into the neighborhood of buying 703 or 705 outright for the same $$.
