Looking to replace deteriorating sound-proofing insulation in the engine room. You know, the heavy foamy stuff about 25mm thick.
Anyone know where to get good stuff?

Bugger. I’ve had price issues with these guys before. They sold me an anode for the Maxprop when I was under the impression it was a specialist size but then I found the same identical anode for literally half the price in Burnsco.

I got my stuff direct from pyrotech (I think thats how you spell the name). let me dig around in my files. It is good stuff. Used in industrial applications. Several different products. The foam product of various thicknesses, with a lead impreganted vinyl and a de-coupling layer. You can also get straight lead impregnated vinyl, which is ideal for filling in around holes and gaps. I use it to make protrusion seals around pipes and cables.

Pyrotek. 69 Cryers Road, East Tamaki. 0800 226 878 I'm just trying to find the actual product I used. Don't get confused with the difference between sound absorbers and noise barriers ;-) Like I said, these guys supply industry with everything. A level above SOPAC and Vybar. Edit, fairly sure we used sorberbarrier: www.pyroteknc.com/products/sorber/sorberbarrier/It is primarily a foam, with a layer of wavebar (vinyl) in it to block the low frequency noise. Has a thin layer of foam between the barrier layer and the face to 'de-couple' the sound waves, to reduce structure born vibration and noise transimittance. All the stuff we got has the special ali-silver layer on the engine side. It is all fully fireproof. I got bored one day and took to it with a blowtorch. Absolutely nothing happened. Very boring. The vinyl product is called wavebar www.pyroteknc.com/products/wavebar/wavebar/www.pyrotek.com/

Brilliant thanks.
That Sorberbarrier stuff looks like what I’ve heard about - a thick foam construction with a thin layer of something else in the middle rather than on the outside face.
I’ll def give them a call tomorrow.
And decide overnight which child to sell.

The Vybar is a superior product to that from Pyrotek, does not come apart over time. Lloyd Stephenson, Scott Lane, Dave Pachoud et al use it in the launches they build with Lotto price tags

Lloyd Stephenson, Scott Lane, Dave Pachoud et al use it in the launches they build with Lotto price tags I'm sure the Pyrotek product doesn't come apart over time either. I can't remember how long we've had it now. Possibly the 5 to 7 year period and it is fine. BUT, when I was researching all the products back in the day, I had a specific discussion with the rep from Pyrotek about it falling apart. I'm sure he said it doesn't do that. Has a particular technical name - hydrolisis I think (or something sounding like that). Yes, there are cheaper foam products that will do that. But not this one. I would think this and Vybar are on a par in that regard. But with the Pyrotek you can get it from the distributor, not a retailer like SoPak, and you can get a couple of different options, like thickness etc. In our situation we got two sheets of the sorberbarrier and a role of the wavebar, the wavebar to make gaskets, cable protusions and generally sealing difficult spots. In saying that, I couldn't comment as to why the Lotto launch builders use Vybar. Possibly it is something as simple as them already having an account with SoPac, getting other fittings from them, and getting the Vybar while they are at it?

Cause I'm bored I had a look at the product statements between Vybar and Sorberbarrier (Pyrotek). Vybar has a catagoric statement, while Pyrotek has a loose, wooly statement. So that would support CZ's comments.
VyBar® Marine is an extremely robust aluminium faced insulation with an indefinite life. VyBar® Marine does not shed fibres and will not delaminate; it is unaffected by vibration, oil, water and hydrolysis.
SorberBarrier "Engineered to resist degradation (foam rot) more than traditional accoustic foam".
I note that Vybar is a rigid (or semi regid) sheet. Which has to be a pain in the arse to install. The flexibly foam nature of SorberBarrier will win hands down on the installation aspect, being a retro-fit rather than a new build.
