automotive sound deadner heat shield

[Deleted User]

I have a carpet kit coming from Bob, and am wondering what other Hudson folks suggest I use under it for automotive sound deadener / heat shield.



Suggestions? Sources?

JC Whitney sells both adhesive and non-adhesive mats for heat relection. Prices are reasonable.

Prices are less reasonable, but better quality is Dynamat Extreme and Dynamat Liner. Do the search on the internet for "Dynamat". I don't use anything less.

Is it all adhesive? What did you use for the floor, doors, ceiling? It does seem expensive, but I only want to do this once, and I want to do it "right"



For now, only the carpet will be permanent. I am just putting the rest back together until this winter, when I hope to have the fabric I need to have the interior redone.

It's all adhesive backed. The Dynamat Extreme is a good heat shield. The DynaLiner is a good sound deadener and insulator. You can do as much or as little as you want, but minimum, would be to use the Dynamat Extreme on the floorboard, trunk, firewall, along with the insulator additionally on the firewall. To go further, the roof, doors, inside quarters, sides of trunk could be added.

I reccommend buying the roller they offer to aid in installation. All of this can be cut with a razor blade, utility knife, scissors, whatever. Difficult pieces can be made by utilizing a cardboard or paper template beforehand. Good weekend project.

Oh, don't forget, you still need to leave the cover plates for the Master Cylinder and the transmission hole accessible. Also, I have thought about cutting out a "door" in the carpert, and stitching around the 3-sided flap to eliminate having to pull the carpet all the way back out of the way during maintenance time.

I've used this on 4 cars with excellent results.

Thanks for the information. I also plan on using black enamel paint on the floor to seal things up a bit. I like your idea, but now I just have to find the time to work it out Thanks again.

Do it Walt's way and save a pile. This is how I did my car and 12 years later it's still quiet. It now shows 130,000 miles in 12 years. Clean the area good and wash it with a rag with brake kleen and dry. Get roofing heavy tar paper. Make a pattern out of heavy paper were you will be applying the tar paper, then cut tar paper like pattern, brush on a good undercoating and apply tar paper. You can do this for every part of the car but not the roof. When I give a ride to some one they say, boy this car is quiet.

You don't need to get dynamat and pay dynamat prices...basically what it is is Butyl Rubber. You can get it at your local hardware store adhesive backed...it's made for roofing...they sell it in like 50 yard rolls at $70 but if you did your whole car it would be cheaper.... you can get a lesser "trimming" quantity of the stuff for about $15.



The other insulation is upholstery insulation and that can go under a carpet and looks like a sheet of lint (sort of) and can be purchased at upholsetery supply houses in rolls. I used both, both do work.

HETers that subscribe to Auto Restorer have seen this product used on a '46 Ford coupe.



It isn't cheap but it is a spray on product.

I used the product from insulation4less in my '81 AMC's headliner. When it snows overnight and then I drive 44 miles into work, the snow and ice are still there. I used 3M spray adhesive and laid it all over the floor and door panels and roof on my '51 sedan. I believe that it has a better db level than the standard dynamat. It all boils down to how much you want to spend and how much research you want to do on all of the different products out there. There are many! Good luck with your choice.

Try "Peel and Seal" as a cheaper alternative to Dynamat... for sound deadening you don't have to cover everything but why not? Double up in problem areas and come back with a more traditional (and cheaper) insulation (modern equivalents for jute work well).
