How essential is the Dyanaliner when used over Dynamat? It's be used to soundproof my car doors. Will it make a noticeable difference?

It's good stuff and will reduce all door metal rattling and nasty sound from outside

I did not use it on my car. I used it on the underside of my stainless steel kitchen sink to deaden the sound. I did three coats. It has worked great.

This product was not designed for applications such as a fridge compressor or other sources of heat. It is intended to be placed on sheet metal surfaces like that of the inside of a vehicle door as a means of absorbing vibrations, based on the heavy foil construction I would expect Dynamat to behave as heat shield and could result in the compressor to overheat. Depending on the type of the refrigerator it may be possible to place this material on the flat surfaces however some fridges need to expel heat from the exterior walls of the fridge. I would recommend that you not use Dynamat for your refrigerator. Consult your fridge manufacturer for suggestions on how you can correct your noise problem.

Austin M., you're going to have to do a little math. Measure the door panels and trunk (floor board if you're installing), all for length and width. That will tell you how much you need. I ended up getting a quantity of three, which covers the trunk sides and base, and four doors of a 2008 Impala (a large sedan). Combined with Dynamat, I never hear but the loudest cars-semis, and only after they're flanking me or right beside.

I have never used the product in an effort to make speakers sound better, I am guessing mats would have a greater effect. This stuff did help quiet the noise in the doors on a '51 street rod I own, I put some insulation in the doors as well and using the two together helped a lot!

No. This product is a reflection-absorber, not soundproofing material. For what you are discussing, you will need a different kind of product (essentially, sheets of dense rubber such as Peacemaker). No matter what you do, it's going to cost dearly, and not be particularly effective.

Mostly because of the cost, but also, because this product, like Dynomat, is a vibration dampener rather than a sound absorber. The way I figured it, if one layer of 50 mil didn't do the job, I'd put on another layer over top of the first one. Turns out, one layer does just fine. I won't do a full review here in the responses, but this is good stuff.

The remaining pieces of Dynamat from my vehicle were used to block a heat duct in my basement during the winter because the temperature is at least 65F. The Dynamat has stopped the heat exchange from the duct, totally. My suggestion is to contact Dynamat, directly because I have no experience in heating and refrigeration. The Dynamat is absolutely perfect for a sound barrier.

Hello. As a purchaser of this product, I have been asked to answer your question. This stuff is super tough. However, it has limited spring in the material. It would definitely serve as a sound barrier. I hope this helps. Good luck.

I have used this product before, I suggest that it only be used (mostly) for your car's interior. I don't know what the temperature resistance is, however, this has a tendency to be dusty if used outside on paneling, body trim, etc. It really depends on your application. If you're applying this directly on any hot engine parts, near exhaust, and so forth, I highly advise against the idea because it will definitely distort and damage the material (also a fire hazard).

I've heard that using sound deadening material will do exactly what you want for your cart. I included a link below to something that I think would be even better. You're basically adding mass in order to change the harmonic resonance, i.e., stop rattling.GTMAT 12 sqft Constrained Layer Dampener Automotive Audio Sound Dampening Sound Deadener Deadening 80mil ULTRA - Audio Deadening Installation Kit Includes: 12sqft (qty 3 - 36in X 16in sheets), Instruction Sheet, Application Roller, Degreaser, GT MAT DecalsAnd after doing this, if your cart is still too loud, look into a muffler silencer. They are cheap and easy to install and will most definitely cut the noise out. I've heard that using sound deadening material will do exactly what you want for your cart.

Made no difference in my application. However I wouldn't purchase this product again. I is very quiet, I often wonder if the one I got is defective?

I got the 39045 kit and it has an extreme amount of protectant lol. I had enough that after i used the kit i wanted it smoother and i went and got a big 3000 grit pad from autozone for like 5-6bucks and did 2 really good layerings of the protectant. I definately suggest getting another 3000 grit or 5000 grit pad with the kit and use the extra pad after the kit.

Best use is behind door panels, behind trunk liners, it can be used in headlining. But this is not a Roof replacement material. It is special aftermarket sound deadening material.

This product is to be used on top of the Dynamat so if you just use dynaliner. I don't think it will work as well.

Installation requires removal of interior trim of doors or ceiling, then cutting pieces of Dynamat to be bonded to metal sheets and re-installing the trims. Another thing is knowing where to put Dynamat, usually it is not necessary overall. In my case, I got very good results by putting it on the ceiling only.
