Regarding Acoustic Foam

[ale_recording]

Hi guys! I have a quick question that i was unable to find using the search function...

I have a local suplier of foam acoustic panels (similar to auralex wedges), but they are made from standard polyurethane.

This material has no fire retardant treatment...

Now the two questions:

1) Is Standard polyurethane (with wedges design) a good idea for Highs absorption?

2) Can i go ahead and buy this stuff and the spray them with a Fire retardand product to make them safer ?

Thanks in advance for the feedback.

Best regards!

I forgot to mention.... the foam is "open cell" type and 18 kilograms per cubic meter (18kgm3) density.

Cheers.!!!

i think if the foam is not fire retardant, you should look at other products. i don't think you can easily add fire retardant to foam like you could cloth. maybe if the foam is used in enclosed applications, it could be useful. some info on why fire retardant foam is important http://en.wikipedia.org/wiki/The_Station_nightclub_fire

Glenn, thanks for your feedback!

According to a product manufactured by a Major (and respectable) paint company here in Argentina, their fire retardant can be apllied to almost anything (including foam).

Please take into consideration that i have a small rehearsal room with private use only (not commercial) and that i'm taking every necessary precaution to prevent a fire (no smoking allowed, no electrical wiring "stiking out", circuit breakers, grounding, etc).

Having said that, im not minimizing the risk of a fire in a small room in any way.. actually im very concern about this and that's why i'm asking the question regarding the fire retardand products.

I see that is use commonly for cloths.... can i assume that it will work on this foam ? (the manufacturer of the product says it does)

What do you all think ?

Anyone had experience with this type of foam before ?

P.S: Im not looking into DIY acoustic solutions at the moment, as (believe it or not) many of the materials will be more expensive than this type of foam.

Cheers!!!!

maybe the fire retardant product company has some material specs which shows it works with your intended foam product.
