Sound Deadening

[85_Ranger4x4]

What does a person look for in what to get?

Any idea how many square foot a standard cab first gen is? I am thinking 18 sq ft should catch it pretty easily...

Not looking for soundbooth quality just to kill some road/gravel noise. I see some is waterproof which is appealing, it almost seems like the stock stuff holds moisture.

I think Rangers are pretty quiet inside I had a regular cab 4wd, 4.0
I now have a super cab 5-speed 4.0 it's even quieter I'm pretty happy with that

I'm not up on the technique, but there's definitely a time and place for butyl/dynamat type products versus mass loaded vinyl. I think you typically place a layer of dynamat or similar on the vibrating metal to change the frequency, where MLV is used to block external noises transmitted through the air.

I am replacing a floor pan in my '85 so I will be losing the stock stuff on half the floor. Its already gone actually, it came up with a shop vac from my rusty floor pan.

I am going to remove the stock insulation stuff on the rest of the cab floor, bedline or somehow seal the floor and then start over with new sound deadening and new carpet.

I have seen butyl and some kind of closed cell foam... don't really know what I am looking at.

Its a "Custom" truck with minimal plastic trim and no insulation anywhere aside from under the carpet so I don't think it will ever be really quiet. I am taking something away, I would like to put something back.

For size I figure 5x5 would probably get me kind of close, comes out at 25 square feet. Figure in the dip in the floor pans and tranny hump 36 would probably catch it. Torn if I want to rip the dash out and do the firewall too.

That is actually the one I was looking at. I only remember seeing the aluminum backed stuff (dynamat probably) on the car tv shows.

Then I found:

Then I saw the second stuff was waterproof. I was wondering how they compared is all.

Closed cell foam can be used on top of a layer of CLD as I understand it. You'd use it in places where MLV would be too heavy, like the roof.

Or at least, that's how I understand it. Still wrapping my head around this stuff.

It gets confusing.

I have a steel headliner (low trim level) so the roof is a nonissue.

I found this stuff for a little cheaper:

Same thickness but a little lighter. I see in the comments someone asks if that makes a difference and they say it does.

Conundrum... having a base model truck with a basically steel interior (steel roof and rear bulkhead, just vinyl panels on doors) should I go with the better stuff to get as much benefit as possible or save $10 and get the .2lb lighter per square foot stuff and probably not be able to tell the difference because the rest of the truck will make so much noise?

I do like the smaller sheet size of the Kilmat.

The floor is the main thing I want to do. Depending on extra I might do some of the rear bulkhead and doors. It .sounds like people are doing crew cab fullsizes with 36 square feet.

I did find this stuff is more for vibration, closed cell foam is more for heat.

Walmart sells Hushmat at great prices.

I know I’m late to this. But I’ve use fatmat for years now with great results. Usually a 50sqft roll is more than enough to do the entire cab.

I’ve used Noico as well. For the little price difference. I like fatmat better. Sticks better. And seems to dampen the drone better

 

[85_Ranger4x4]

I have the noico but winter hit before I could get it put in.

For what little it worth it is neat looking stuff.

I'd personally steer clear of using ANY sound deadening products or vinyl insulation-backing on the floor pans, but that's just me.. Doors, roof, kick panels, rear section of the cab, and forward/upper floor pans or interior firewall would be fair game, but anywhere water could collect I'd stay away from..
