slimjim Posted August 10, 2011 Share Posted August 10, 2011 Just picked up my sound deadening stuff from my friend Paul who owns Classic Acoustics. http://www.build.co.uk/company_409669.htm (Their own web site should be up by the end of next week) He makes sound proof rooms for a living and also does all the sound proofing for JCB's Lucky me has been given a LOAD of stuff. Two HUGE sheets of "AG-Barrier FO12(PVC Based)"... which to you and me is Dynamat. And a LOAD of "Type O Acoustic duct liner" which is AMAZING sound deadening stuff. Paul says that he can accommodate ANY sound deadening needs. So if you guys want some, mention me and he will sort you out. For what he gave me (Including a load of DECENT glue) he said he would charge £90 for people to fetch it. Working this out with dynamat prices it would be close to £800! ring em... 01952 587360, Ask for Paul, tell him James with the 350Z sent ya Quote Link to comment Share on other sites More sharing options...
Coppz Posted August 10, 2011 Share Posted August 10, 2011 Heavy ? I like the sound of a soundproof (bombproof maybe) room.. Quote Link to comment Share on other sites More sharing options...
slimjim Posted August 10, 2011 Author Share Posted August 10, 2011 Heavy ? I like the sound of a soundproof (bombproof maybe) room.. The stuff is actually pretty light. But I am looking for good sound and road noise deadening, so I am happy to trade that for the weight. Wouldn't be putting the subs, comps and amps in if I was worried about weight Quote Link to comment Share on other sites More sharing options...
Chris`I Posted August 10, 2011 Share Posted August 10, 2011 The only heavy part tends to be for dampening the metal panels and you dont need to do a huge amount of them. A lot of the noise in the Zed comes from sound reverberating around the cabin space which I found that soft foam works quite well and doesnt weight much at all. Spoke to an Alfa technician the other day about rattles in the new car and he said they usually just stuff the areas of trim with soft foam type material too to stop them Quote Link to comment Share on other sites More sharing options...
slimjim Posted August 10, 2011 Author Share Posted August 10, 2011 Heard from a few bods that a little of this mat goes a long way if it is being used for stopping panels reverberating. Just a few strips makes a HUGE difference. Obviously I will be doing the door skins (inner and outer) fully. But the rest can just be lots of strategically places strips. Can't wait to get my hands dirty with it now... but I have to wait till my dents come out of the doors on Tuesday before I can do them.

Spoke to an Alfa technician the other day about rattles in the new car and he said they usually just stuff the areas of trim with soft foam type material too to stop them MLV I believe is heavier than the butyl based dampening mats? Wish I had luck with foam, didn't seem to make any odds for me (Second skin luxury liner has ccf and mlv). If you're after road noise deadening, you can probably do a better job than I did and get some luxury liner in the wheel wells/inside of the dash area. I found that you couldn't fit luxury liner around the spare as it pushed it up just a little bit too far Don't expect miracles though, the amount you have to add and how thorough you have to be for any significant difference just wasn't worth it for me.

slimjim Posted August 10, 2011 Author Share Posted August 10, 2011 I hear what you are saying RisingPower. Took most of the car apart to fit the bits and bobs I needed too, so I might as well chuck a load of this in while it is all apart. Was going to try to put some in the spare wheel ... Thought I might get away with it but I might not from your experience Suppose I could raise everything else up a bit too Quote Link to comment Share on other sites More sharing options...

Thought I might get away with it but I might not from your experience Suppose I could raise everything else up a bit too I put a layer of damplifier second skin down, then tried to put a layer of luxury liner on top. It didn't work, it was just ever so slightly too thick Damplifier is fine down there though and tbh, I think it helps more with drone than road noise. It's a pain, because that is where a lot of noise comes from. If you can get some in the dash area/wheel wells, that would be interesting Quote Link to comment Share on other sites More sharing options...
