Sound deadening insulation stages and how many sq ft double cab taco

hi folks me again just trying to figure out how many square feet inside the double cab Tacomas needed indeed to install my vinyl flooring before that I need to cover some insulations inside cabin just the floor and back seats area
does anyone know what exact sq ft that I needed to buy if references I would be appreciate it folks thx again happy weekends

 

Not sure of the square footage, but as far as the stages...

from the outside

damper
decoupler
barrier layer
decoupler

(shown in reverse order below)



works well for me.

Maybe break out a tape and estimate 25% on the high side. Good dampers don't require full coverage but barrier layers do.

 

KILMAT 80 mil 36 sqft Car Sound Deadening Mat, Butyl Automotive Sound Deadener, Audio Noise Insulation and dampening

Siless Liner 157 (4 mm) mil 36 sqft Car Sound Deadening Closed Cell Foam & Heat Insulation mat - PE Foam Sound Deadener Material & Heat Barrier

I Have these are so far do you think do I needed it more of it

 

For just the floor & back seat area? That's probably close.

 

could you please tell me do I needed it more please thx

 

I dunno - been a while since I've done that.

Confucious say - man with tape measure get close enough

 

is it 36 sq ft or 56 sq ft

 

yes

 

YMMV but I was able to cover the floor and up the back wall with 30sqft of material. It was very close though so a bit more won't hurt. That was just my experience.

 

ok thx

 

How many layers are you going to add? I did this mod as well, and in my opinion, one layer is not enough. It does a decent job of quieting excess noise, but you won't get that true quietness without more layers. Also you're going to hear more noise through the firewall if you don't remove the dash and throw some layers on the inner firewall as well.

 

I used 2 packages & 2 rolls for my Xtra cab. I did it with the interior completely stripped so I was pretty thorough with my coverage.

 

Doing a couple layers in the door really cuts down on wind noise especially when you do the roof.

 

thx I'm looking forward to do it
