D90 #497 Noise Reduction Project...!!!

Ok, so the first project with this great truck is to reduce the noise...(my ears have finally stopped bleeding from the co. trip). I am currently installing Dynamats EXTREME sound reducing pads. Have to say I thought they would be thicker! Starting in the cargo area. Not too much of a problem...yet!

Does the dynamat have a tendency to hold moisture?

I dont belive it would...it's a tar like substance with foil backing. The thing I like about it is the seams will meld together on there own even without the tape you can buy from them. I have the rear cargo area done 3/4 th's of the way and it really helps. I'll finish the rest of the cargo by the weeks ens and start the front the weekend after. The down side is this stuff isn't cheap!!

It doesn't, only the hoodliner version does.

I'm doing a similar project but concentrating on the front seat area and doing it more for heat as my truck is a ST. Will be interested in seeing your final verdict on the effect. Where are you buying the Dynamat? This stuff gets pricey!

Does the Dynemat keep the heat down as well as noise from the footwells? I've been thinking about heat reduction up there. I thought some people had good luck with foil backed acoustic mats.

I'm buying it from their web site. It was shipped really quick.

I think it will reduce the heat but I havent made it that far yet. It does reduce the noise in the cargo area. I'll keep posting updates as I go...

Jeff, I want a ride in your truck when you're done to see the difference Dynamat makes!
Trapping moisture in the footwells was my biggest reason for not using this stuff.

I did my doors and tub. I didnt do the footwells as I was convinced it would be wet and gross. I can't tell the difference other than the doors sound like a german car now

I can't verify in the Rover but I did the entire floor of my '69 Mustang that has long tube headers that basically stop right beneath your feet and it made a huge difference in both interior noise and heat.

Woody, I hope to have it all done by the October HH so you can check it out

sound proofing

I used foil faced, self adhesive, heater duct wrap. It is about 1/8" thick closed cell foam. Installed under hood, doors, under floor mats, seats, behind dash, rear tub & sides under rubber mat, basically everywhere that I could not see the material after installation. Big difference in heat & sound; panels have a "thud" when knocking them. I hose out the 90 regularly...closed cell foam does not hold water. The only problem so far (1 year) is that the foil face has peeled slightly (very thick material) when I hose out under the hood. Best part; Lowe's carries it at about $15 roll, I think I used 4 rolls total. I also replaced the vinyl under the seats with grey outdoor carpet, cut to match, using heavy duty carpet tape...love it, as it dries out quickly.

good luck
