Hi there

As mentioned previously, just be sure to remember that - according to the guy I spoke to - Isover make different products according to different countries.

I was hoping to get some Akustik TP-1 or similar (that's available in Germany, I'm in the UK). When I spoke to someone at Isover about this, they said there was no chance of getting TP-1. Neither was he able to tell me of an equivalent type of product in the UK range.

Good luck mate

Max

what's the density and the air flow resistivity of isover products you're looking for?are u able to get this infos?? (i actually convinced the retailer to call his supplier and find out all infos related to URSA material, so i guess you can try the same).

what are u gonna use it for?

everything depends of what you need it for....
early reflections?
Bass trap?
Really Bass freq. trap?
plus there are few aspects to consider:
how thick can you make it? (i meaa how much space can you take from the room)
how are you going to make the traps? hang, on the wall, etc etc
all these questions because it's a mix of factors that makes a material better than another.

Most likely bass-broadband absorbers. Around my desk area i can space panels max 2 inch iff going for 4 inch thicktraps. Further in the room i can go 4inch gap. I don't wanna make my panels more then 4 inch. Tough now i have realy light stuff so im considering to build a monster 12 inch tram for the backwall.

I need Isover product recommendations based on a europe based production. My eye is at the moment at what i mentioned above.

I have contacted Isover myself, all they manage to do is saying: check out the ''technicall'' pdfs off each product'' But it doesn't mention densitys nor G.F.R. So i don't even feel like asking anymore, but rather ask expierience from people who used isover stuff.

as mentioned by Max Dread before, probably in Europe there are different materials by Isover.....
the datas I know for sure are:
E100S: 44000 Rayls/m
E60S: 22000 Rayls/m
PAK 70: 6000 Rayls/m
IBR N: not specify but I know it has the same density as PAR 70 and sometimes it's easy to find than the PAR

Those are products that i can't get over here i think =O.....
Tough sonebell product i posted has

Frequentie (Hz) 125 250 500 1000 2000 4000
25 mm 0.34 0.77 0.88 0.92 1.03 1.07

Can't find GFR, nor desnity but i think these numbers will wokr very well at 4 inch. No ?

[PaulRain]

My french is not super, and my dutch it's nothing but, if I'm not wrong, those coefficients refer to a 25mm panel 250mm far from the wall.....and I will say, yes maybe the coeff are right.
But you can get much better result with a cheaper product in my opinion.

Big company, with different identities and product names in different regions.
I have been able to buy Isover High Performance Duct Cladding here in a little City on a small Island. Performance is better than 703 at bobgolds.com
You may find this stuff at industrial HVAC suppliers, rather than normal building suppliers.

Absorptiioncoëfficiënt (αs) By ISO354 for a thickness of 25mm in a space off 250 mm. Is what it says. This insulation is used for ummm i don't know the english word: Fake ceiling ?. Not your main ceiling but iff you want to lower a ceiling they make a wooden frame and put that insulation in there.

The pdf says this product is made as acoustic insulation for ''fake ceilings'' and prevent echo in rooms ? (this is realy a plain translation from what i read).

Hey DanDan, wel at the store....I saw he had isover in stock and asked him wich Types it where (what products) but he dident understand me. So i tried to explain what my main goal whas and then he stared talking bout insulation with rubberi n between (no,no no). Then he told me i can come back with a sample or something and he can get it for me. Cool guy . BTW: its not that for from me,maybe he'll deliver it 2.

Tough industrial HVAC suppliers don't gonna be bothered with me for 1 pack off insulation.....they only gone talk bizz if it,s a sh*tload off orders. Like 2, 3 trucks.

3th list has all URSA products, click on a product to see tehcnicall info (no densitys or GFR but absoprtion coefficients.

You'll see that they aint very effective.

Damn why does it get so quiet when a question is asked where OW doesn't get mentioned. Help a lost-frustrated brother out.

Well, I looked for OC and rigid Rockwool for literally a few years until I found a company who did industrial work. They were more than happy to sell 6 packs of the stuff, even during the building boom here.
Thing is, normal builders don't use rigid panels often or at all. HVAC and factory guys do. BTW I believe the European HQ of Owens Corning is in Belgium!
There are many other EU suppliers and products. e.g. ACTIS Isolation - Isolation fibre de bois SYLVACTIS
Or Homatherm etc. etc.
You could hardly be in a better place!

I've contacted homathemr but never got an anwser back.
And this place do sucks my friend, i whas watching the news yesterday and the international bank system or something ? (you know that place where people go bananas if they drop 1% or 2),warned belgium to solve their politic problems and make their economics run beter or they gone drop the value off this country. .....

DanDan ?, coudl you maybe try to contact em cuz they don't reply towards me ?.

[DanDan]

I think you will find the whole world is in the same financial toilet.
The governments have decided to have the taxpayers pay the gambling debts of the international bankers. You could put a w at the start of that last word if you wish. It is unfair, it will have to be solved in some way because the future populations of Greece, Ireland, Spain, probably Italy and Belgium, etc. etc. simply cannot pay a gambling debt that they had no hand in.
There will be a solution or a revolution.
I may end up in Belgium after the summer, so I will sort out the EU then.....
