Great stuff in doors

[LewPoberezny]

Has anyone filled their doors with Great Stuff or anything else to make them sound more solid when closing?

Yep, there are a number of ways to do this. I just had my painter do my doors. He used a structural foam. Basically you mix part A and B inject it into the door and about 2 minutes later it's all done.

The stuff you buy at home depot will work too. Just make sure you use the low expansion stuff. There was a posting on the old forum a number of years ago of a door that was severely distorted from using a high expansion foam.

This procedure certainly makes the car quieter and makes the doors feel more solid.

Bruce is right, go slow and layer, let each one expand and do another, take a couple of days to do it as it actually keeps exspanding for about 24 hours. It can bust the seams if you overdo it all at once...........HTH Steven

I'm thinking some extra holes to allow the foam to expand out and also make for an even fill of the gap. Not that these cars see much rain, but I had an old sunfish sailboat and the foam inside absorbed the water after awhile and became super heavy. Wondering if there is a difference in foam that would not absorb water. Even condensation. Just a thought.

Great stuff works well, go slow and in stages. The difference in the feel and sound of the door is greatly improved. I mostly put it in the areas around the steel door frame and the larger cavities, left the bottom of the door unfilled so if any moisture does get in it has a place to drain.

where would you inject and how would you lay the door when filling?

You can also use the less expanding foam made by Great Stuff. Lowe's has it in the blue labelled cans.

I use Second Skin Audio on all of my doors. Easy to work with and makes the doors heavier and a much nicer sound when closing.

My painter noted that it was a very time consuming job to work the door contours , as just a little too much pressure would push in the thin door skins. If I did it over again, I would foam fill the doors to make the outer skins more rigid, as well as make the door sound more solid when closing.

I used low expansion foam on my doors too. Only put it near the spots where there was steel structure to tie the door together and minimize that hollow sound. Really like the feel when the door closes. did it before paint so the holes got filled. you could do it later a just buy Herb's panels to cover up!

I like the sound of my doors with the foam inside. I actually drilled 1/2" holes on the inner panel to allow the foam to expand without causing pressure, filled the holes with HSRF a week later. It makes them sound more solid and more rigid for body-work. Used the same stuff between the frame and interior area in front of the doors to keep the wind/rain from coming in.
