SS is more massive, well engineered and very effective. RAAMmat BXTI is crap. BXTII is really quite good, but is thin and may require double-layering in places to get the same performance as SS. I do really like the BXTII product though and will continue ordering it as I need it.
Cascade ...can't comment but I recall they they use similar technologies as the others, while still trying to be as light as possible. Effectiveness? <shrug>
I can attest to the great quality of the Second Skin stuff, Ant sent me some samples and it REALLY is a SUPERIOR product to damn near everything else I have used before...I think it beats dynamat extreme like a wife that wont make you a sammich
No love for BXTII, huh? At least it doesn't turn your hands black with goo anymore. BXTI had a serious issue with this. I don't know, I like BXTII's properites. I also LOVE Don's cld tiles but sometimes they are just too damn thick. BXTII seems to work in concert with cld tiles.
I have never used SS. Yet, BXT2 was very effective and priced right for my install

I can't speak about the Sound/function difference. But I just (15 min ago) finished installing ~80 sq ft of Second Skin Damplifer (the black stuff on special) in my Tundra. My only other experiences are Raamat BXT (original) and some no-name stuff years ago.
The SS is MUCH cleaner, no residue on my hands.
The thicker foil is harder to work with and follow sheetmetal contours. But I'm sure the function is better. But it's the first time I've gotten cut from the foil layer while installing.
bxt is signifacantly cheaper and works better than most but if your not satisfied just add another layer!
Fair to assume you mean BXTII not I? Because I would agree with II but I think I is a waste. Like most asphalt-based products. There is no visco-elastic properties in asphalt-based products if I recall.
Thanks for the link to sound deadener show room; after visiting there I understand all that's involved (regarding auto sound control- I already knew quite a bit about recording studio/home theatre applications). I found it especially useful information that you don't need to apply constrained layer damper to every square inch of a panel like most people do. I've seen a few install threads on other (vehicle specific) forums where guys talk about doubling or tripling up on Dynamat, then putting the foam layer on and think they did great job. Now I realize that they left out the most important layer: the mass loaded vinyl(or other suitable sound barrier). They put on the decoupler but nothing is decoupled from anything!
It is weaker than either SS products HOWEVER it is close to Damplifier. $99 for 36 sq feet though, and flat packed, not rolled. I hate rolled deadener because you KNOW it isn't Butyl.
Rolled material can be butyl.
But, the foil is usually 2 mils thick, and the butyl is a low grade roofing type.I'd never use rolled mat again since they are simply roofing tape resold to unknowing customers as a vibration damper, simply because it looks similar..
Yes, I get it; the point being, is there some information on the site that is worthy of ridicule? I'm trying to learn about this stuff and appreciate knowing if some info is bogus or not, and why.
I can promise you that I've done everything possible to make certain that the information on the site is consistent with my understanding of the pertinent science. I'm not a scientist or NVH engineer, but I have spent the past 5 years studying the discipline and discussed the topic extensively with many who are. If any of it is worthy of ridicule, it is an error or oversight and am always very happy to learn.
Rudeboy knows his stuff, and the info on the site for SDS is solid. The products and info on the site goes to show that Don spent the last 5 years testing this stuff (the old SDS site was reviews and tests of other companies before he started selling his own stuff)
I have recently used both SDS tiles, Second Skin SPL tiles, and Second Skin damplifier in a single car.
I also have experience with older Second Skin stuff, current and older (assphault and aluminum) Elemental Designs stuff.
1. I like the sheets and tiles better than rolls. Easier to work with, lay out without sticking down, move around, etc.
2. Dont waste money on the ED stuff
3. While I like the Second Skin damplifier, the SPL tiles are too thick on foil, and d not conform well to ANY changes in elevations. Any bumps, ridges, dips, divots, dimples, etc. It really hurts the SPL tiles.
4. The SDS tiles are noticeably thicker than Damplifier, but again, noticeably thinner and easier to work with than SPL tiles.
5. The extra thickness on the SS tiles made it much harder to cut to smaller pieces when needed as well. The SDS tiles were easier, but less so than regular damplifier.
6. All will still cut your fingers if you arent careful. Trust me.
Until Don started selling SDS stuff the Damplifier and Damplifier pro were some of the best you could buy. Cascade stuff goes above and beyond simple cld products, and has a line of stuff that is amazing as well.
At this time I choose to support Don and SDS, and have yet to be disappointed in quality, shipping times, or general service and help that he has provided.
He went so far as to shoot me info on another clients car (same as the one I was doing) and let me know what worked and didnt, where to pay attention, etc. This is the kind of info that you only get from knowing the product and cars, install methods, and simply caring about customers.
