I have 36 sq. feet of dynamat extreme on order now. I have a couple of questions though. Is this enough to do the entire cab and do I also need to add dynaliner afterwards? Trying to get everything I need on hand. Thanks in advance, Steve

 

Is that a roll? I don't remember how many square feet was in a roll but I used about 1.5 rolls on my 48 and I did the entire cab...

 

its not enough.. the floor alone is 5x5, so 25 sq ft.

I used just 100sq ft for everything.. , roof, doors, back wall, floor, kick panel to the cowl seam.. had about 2 sqft left over.

I used 80 mil Rattle Trap (from ebay), this was for noise suppression

then I used a foil backed foam insulation, 2 rolls of 48sqft each. (4ftx12ft)

then we layed the jute carpet pad over that, and the carpet on top

I used about 36 sq. ft. of Dynamat on the floor and firewall of my '56. (The roof and rear wall were completed by the previous owner.) I can't remember the exact amount of Dynaliner that I used because I didn't cover everything with the Dynaliner. You can look at the pics in my gallery to see exactly what I did.

 

Instead of thinking, I found an old post of mine right after I did the project:

I bought the bulk pack (36 sq. ft.) of Dynamat Extreme and used it to cover the entire floor and firewall of my '56. All 36 square feet of the package was used to cover EVERYTHING. (There are pics in my gallery) I purchased the Dynamat from Amazon for $138.00 and shipping was free. I also used the 1/4" Dynaliner to help with heat and sound issues. I believe I bought two -12 square feet packages for around $40 per package. The combination of the two really made a difference in terms of heat insulation and sound proofing. I really couldn't believe how much of a difference it made!!! I split a second bulk pack with my neighbor and am going to install the Dynamat in my doors this spring.

From the Dynamat website:

You can apply Dynamat in patches (25-50% area coverage) to keep a specific panel from resonating or you can apply it over an entire area (such as the floor, doors, or trunk) to create a sound barrier and vibration damper.

Even a small amount of Dynamat can cause profound noise reduction. For example, applying Dynamat to the doors of your vehicle can reduce road noise from 3-6 dB. Complete coverage of an average vehicle can reduce road noise 9, 12 even as much as 18 dB.

 

Thanks for the info guys. I should have the Cab back from paint next week, so now the fun begins. I'm ordering more dyna mat today. Steve
