Hi,
after a little introducing, here is my first question for my coming studio in Australia…

I did buy all the Acoustic Fields construction plans, because yes, as many others and for a budget reason (also because I like doing things with my hands), I will construct everything myself.

My first question is about your foam and a substitute. Because to be honest, when I saw the international shipping rates, I almost had a heart attack ! thanx ups :))

So in Australia, I found a manufacturer called Fletcher Insulation, and they make a product called Pink Soundbreak :
http://insulation.com.au/produ…..oundbreak/
I know you’re not fan of Roxul, 703, and other things of this kind, but at this moment Fletcher’s Pink Soundbreak is the best thing I found in Australia. It does not mean that there is no something better, but I don’t know if foam closes as possible as Acoustic Fields one does exist in Australia, and I also don’t know if the value Material R-value m²K/W R1.7 for 60mm is good or not in order to make acoustic panels and basstraps (I know, it does not mean anything about the frequency attenuation straightness)…
Hope is not a non-sense to use that substitute,but would you like to enlighten me please ?

Thanks
Greg

Hi Greg, Substitutes can be used in different regions of the world where shipping costs can be higher. I looked at the specifications section of what you sent me, but could not find any absorbent coefficients. I found BTU retention numbers but need to know the amount of absorption that occurs from frequencies starting at 125 Hz. – 4,000 Hz. I would look for another source of products that have these numbers.

Hi Dennis
thank you to answer so quickly

yes, that’s what I thought about the specification, it is very difficult to find product with complete specifictaion.
I will begin by asking them at Fletcher Insulation if they have more numbers, especially absorbtion corfficient or sabin…

and I will continue to look at something else over there.

another question, is it a good idea to constrain more glass wool into the 2″ foam space you specify, like, let say 4″ of wool ?
will it help absorbtion by compensating a poor wool coefficient or destroy it ? I think it is bad because of the needful air wich disappear inside the wool but I prefer to ask…

Hi Greg, There are numerous options for fill materials. Regardless of material used, I still need the coefficients.

Of course… I asked Fletcher and waiting for a positive answer.
I am also asking here and there, and find many other product, without any specification except the size… Should we deduce they are ashamed of the performance ? Maybe…
Still scanning the web…

Hi Greg, I do not know their reasons for not posting the coefficients. However, I do see this a lot from companies that offer building insulation product types. This is one of the reasons I designed and created my own technologies that have been tested and certified by nationally recognized laboratories.

and this is one of the reasons I would prefer to work with your product 😉

but the shipping price can unfortunately not reach an acceptable level for my budget, for 10 foam packs it is the same price than a full 20 feet container shipment… it’s too bad…
maybe you can send internationnal parcels by simple postal system rather than UPS ? or not, I can understand it is not interesting for you…
anyway, I think there’s an international market for your foam, at least me :)))

Hi Greg, We ship products to Australia every month. Sometimes we can piggy back orders to save freight costs. Go to info@acousticfields.com and send me your exact ship to address. Let me see what I can do for you.
