Doghouse sound proofing looks great

When we pulled the RV out of storage yesterday one thing we did was inspect the engine and that gave us a chance to look at the doghouse sound proofing we installed last year.

It was a piece of cake to install and does a wonderful job keeping the engine noise out of the RV.

We used American Mat sound proofing foam, cut to the right size with scissors and/or a box cutter. The foam people recommend those electric carving knifes but we don't have one.

You can read about and buy the foam here.

To adhere it to the dog house we used an automotive headliner spray adhesive that we bought at an auto parts store. It has been on a whole year and through the heat of summer use and the freezing cold of Colorado winters it has held.

The first pic. shows a side view. The foam is pretty thick.


The second pic shows more of a front view. You can see at the top where the foam is compressed a little from fitting on the dog house seal. We trimmed that off this year for a better fit.

2018 Update - The soundproofing is still intact but is starting to dry out and shed fine particles. I checked the left over material in the basement and it is doing the same thing. So the question is do we try and get it off as it seems to be stuck on good and will probably make a royal mess or just leave it. It doesn't seem to be doing as good a job as before at quieting the noise.
