Spray foam insulation in doors?

[wildcattc]

Can you guys think of any problems with spraying foam insulation in the doors for a sound and thermal barrier? I would probably use low-expanding "great stuff" ...could be a shot in the dark, but I thought I would ask.

I would think there is a potential for a lot of problems down the road heaven forbid you have to fix something in the door. I would just get a good sound dampener and you will reap the same benefits but you will also be able to get in there and fix things if need be.

What is the brand of Sound dampener that you use? Dynamat is the most expensive, but reasonable on ebay.

Makes sense about needing to fix the doors.

I used Raamatt by Rick at Raamaudio.com It is very reasonably priced and does a good job. It is like $150 (at most after shipping) for 1 roll which is 62.5 sq ft.

Of Course!! Windows!! I can't do this because of the windows. I could however spray in the bottom 1/4 or so until it meets up with the window when it is fully down.

I have taken out my rear seats and most of the trim to install dynamat (or Raammat) and noticed that there are a lot of voids that can be filled in the spray foam. I think that I will probably try this to help with sound barrier. The foam is cheap enough to try it.

I do agree that even with the added step of the spray foam that dynamat is the way to go.

Doesn’t Ford use a “wet door” design? Check the bottom of your door to see if there are drain holes; there should be one in the front one in the back. Even just coating the bottom up to the window could cover up the drain holes leading to moisture being trapped in the door panel. My thoughts would be sticking to something like Dynamat.

I dont recommend it, but if you decide to do it, make sure you use open cell, non-structural foam. Closed cell foam will dent your doors!!

i can see you now. spraying the great stuff in your truck and all the seams busting loose and your panels buckling. spray some in a aluminum coke can and see what happens to it.

It takes the easiest route out, it wont buckle anything unless you're using a commercial grade, great stuff is meant for small gaps and windows. I use the stuff daily.

I seconds the RaamMat from raamaudio.com. I plan to do this within the next couple weeks. Check out the tutorial on the site for how he does the doors. He puts the butyl material on the inside of the door panel and on the inside door panel along with the ensolite (which is like a foam cloth) that deadens road noise.

only problem i can imagine would be that your window seals are not sealed. This is true of every vehicle on the road. great stuff is basicly a sponge and inside your doors it has nowhere to drain. eventually you will need new doors as a result.

is it a good idea to use spray foam for the roof and other parts other than the door?

I am at a loss as to why one would want to do this. Is your truck extremely noisy? Is it hard to warm up the interior?

Yes Ford does use "wet door" technology. I think all mfgr's do.

But what is the purpose for all this extra work and expense?

Try it on your wifes vehicle first and see what happens.
