Hi Everyone,

For those who don´t know, I live in Buenos Aires Argentina, and here everything is too expensive and hard to find, umm..

I am planning to build some corner bass traps. As rigid fiberglass is so expensive here, I came up with the following idea..



Just in case there´s any trouble with the image, I´ll explain..
I plan to make a "layered" bass trap, across 24" inches of the corner between walls, 6" inch thick multilayer.

1) First Layer, the highest density fiberglass I could get
100kg/m3 (Sorry, I´m on metric). I guess it´s just a bit over 6pcf. This layer is only manufactured in 20mm ( about 0.8")

2) Second layer, a less dense fiberglass, much thicker though..
50Kg/m3, 70mm (roughly 3pcf, 2.7")

3) Third layer: (I need special feed back on this one, please!)
As the 2 first layers are so expensive for me, and just add 3.5" (90mm) together, I wass thinking of getting fluffy fiberglass, make a frame (wood and metalic "mosquito" wire mesh) and compress as much fluffy fiber in there, to complete my 6" total (3 layer summed). What do you think about this? It´s a nonsense?
Should I forget about the wire mesh and just stuff the fluffy fiberglass in the air gap between the rigid panel and the wall corner?
Any idea?

I would really aprreciate your help guys,
thanks in advance

Best Regards

Yes, that's what I'd do.

Thanks for the advice.
I really apreciate sharing with us all the "know-how".

Fantastic for the DIY VLG (Do it yourself, Very Low Budget. Just inventing new acronyms, heh!)
