Adding and upgrading the insulation...
A while back a gave a bit of a teaser about neoprene insulation and promised a write up later on. Here is that write up.
Let me start by saying, I absolutely love the LizardSkin Ceramic Insulation & LizardSkin Sound Deadening I put in (
Post #106). As with anything though, after a little while I think we all get used to the benefits of the things we install. Well, I got used to the level of quiet inside my Rover and now want it to be even quieter.
The LizardSkin has performed above and beyond even my highest hopes; however, the carpet padding I installed, it does preform beautifully at being carpet padding, it is soft and feels very nice but at the end of the day it is still just carpet padding and is not so great at sound insulation. Given the fact that it is a top of the line memory foam, antibacterial, and mildew/mold resistant carpet padding; I didn't think I would find anything better in that area.
So, I began researching for a product that was very soft, fire resistant, mold resistant, germ resistant, very flexible, lightweight, resilient, inexpensive, and not only extremely effective at sound deadening but also extremely effective at heat insulation.
In my research, I came across this build
Project Dino Evo. He used
1/2" thick high quality neoprene. Neoprene fit my specifications perfectly. I bought two sheets immediately. I should have bought 4 sheets to do my whole interior though, because as it stands now, I have done a bit over half of the interior (I will have the other two sheets on their way soon enough).
Those paying close attention will notice that he also laid down a vapor barrier underneath the neoprene. I hadn't thought about this, but it really got me thinking. I did quite a bit more research and found
Radiant Barrier made by EcoFoil. I was less worried about moisture given the fact that both the LizardSkin and the Neoprene are waterproof so I purchased the perforated version, but if I had it to do over again I would have purchased the
Solid or Non-Perforated Radiant Barrier. By the time everything is all glued up the perforations are pretty much not functional anyway in a vehicular application so the Solid would be a better way to go. The Solid Radiant Barrier reflects 96% of the heat back and away, while being a vapor barrier at the same time. The perforated is the same in every way, EXCEPT it lets condensation/moisture pass through so the moisture content on both sides is the same.
Anyway, I bought both the Neoprene and the Radiant Barrier, glued them together and then either placed them over the top of...or glued them to..the LizardSkin. All I have to say is, WOW what a difference! I still have some more insulating to do, but the difference is night and day! Plus the Neoprene and Radiant Barrier are both fairly inexpensive, very flexible, extremely effective, and very light in weight. To do the entire interior is probably around $300 and it all weighs about 10lbs (probably even less than that).
All in all I am very happy with how the new insulation is doing and would highly recommend trying this.
If you have any questions, feel free to ask.
