Need Rockwool for Diy Broadband absorbers

dfer

Hi lads,

Does anyone know a local source for Rockwool RW3 preferably 50mm thick 1200 x 600mm?


Its this stuff - http://www.studiospares.com/Sound-Insulation/Rockwool-Rw3X12-1-Pack-Per-Consignmt/invt/401982


I'd rather buy local than getting it shipped from the UK if possible.

Thanks Peter but i forgot to mention im based Meath/Dublin area

no prob, it's here if you want it. I sourced it through my local hardware supplier, I think there's a distributor in the big smoke.

just out of interest what is the best type of insulation for this type of install.surely rockwool has been surpassed by now by something else?

madtheory

Who said anything about insulation? What type of install are we talking about? There are several grades of RW, hte one you choose depends on what you're doing.

Im not too sure about rockwool been surpassed from a price/preformance point of view (besides plasterboard), anyways the two type of rockwool versions you want to look out for is RW3 & RWA45 there the best for sound absorbition.


The panels im building are based on diy panels i read in a SOS mag a few years ago,

I plan to use 50mm rockwool and mabey double up the 4 corner panels to 100mm.

I've heard of people drilling holes in the frames to increase the bass absorbition, i was thinking of spacing the panels say 5-10mm from the wall, would that have a simular effect as drilling holes in the frames?

I think Chadwicks in Finglas stock it. Not 100% tho

Tell us more about your plans dfer.

A cursory look at the SOS boxes suggest to me that their bass absorbing qualities will lack far behind their mid/hi properties.

This could very easily leave you with a room with a very skewed frequency performance.

This is a very, very common occurrence in studios I've seen in Ireland.

Yes i'm aware of that Paul, it happend to me in my old house i had the place literally cover in auralex Primid tiles and it killed all the Top and mids, which is good and all but say for mixing its not ideal as nearly no person (end user) has an totally acoustic dead room. come to think of it, talking in that old room was weird like (no reverb at all), its was extremely unnatural and uncofortable, you know when you listen to a speaker that has flipped phase... that's what my ears felt like.


Anyways, the new room i'm in has the common problem in a lot of small rooms is with the low end & standing waves. My other problem is that i'm tracking and mixing (Vox, Guitar, bass, no drums), my idea would be to make it acousticaly neutral as possible. So i'm probably going to start off with 4 corner bass trap with 100mm rock wool, 1200 x 600 frames and i also have 4 x auralex lenrd bass trap too and see how that works out and go from there. Unless you guys have a better way of going about it?

Anyways check out the photos of my diy iso box - http://www.flickr.com/photos/36398372@N02/?saved=1 (for some reason i can't upload them here?)


The iso box has helped out enormously with my live/control 1 room setup, but the low end sub bass is creeping out which is adding to the over all low end standing waves problem in the room. : (

Give Gary a shout at Muzzle, he should sort you out with delivery and all.

Cheapest place I've ever come across in Dublin.

balducci

Encon in Northpark Business Park in Finglas, straight off the M50. They do slabs of rw3 and rw5. I can't remember the exact price as it was a while ago i bought them but a pack of 8 slabs was roughly €40. that was the 50mm thick stuff. they do other sizes etc. They're a direct supplier to the building trade so no middle-man costs are involved. I don't know if they are the cheapest but they were the handiest place for me and they deal with the public as well as tradesmen. Hope that helps.

i had that issue DFER - the room was so dead it was like it sucked the very exisstence out of the air .

so i got i moved all the rockwool into the corners mainly - its about a foot to 14 inches thick over 3 corners wallto ceiling . treated the relection points to side , and left the rest bare

sounds alot better now , and measures pretty well.

the thick corner fills really flattens the bass and kills the bad nodes very well .
