Insulation - Foam spray vs. regular insulation

it is the best there is. nothing comes close. also better for pests. Fiberglass is nesting material for mice and squirrels and the like.

Just get a cat.

I answered this in another thread regarding the same subject. I had a problem because I was an opera singer and it drove my next door neighbor (in a large condo building) nuts. I explored the options and ended up using the fiberglass foam to fill the common wall between the living room and bed alcove. It was amazing. I could sing as loud as possible, and he couldn't hear a thing. Also, I couldn't hear him shouting at his lunatic girlfriend, so it was great for us all. I highly recommend it. Make sure you use a company familiar with the product and the mode of installation. It requires many holes in the wall and making sure it is properly loaded between the studs (which are probably wood in your place).

Good luck!

There is no such thing as fiberglass foam. There is fiberglass insulation which is installed in panels or "blown in" OR there is foam. There is no combination of the two. For heavier sound insulation it could well be better to use blown in fiberglass. But make no mistake, it is not foam. If your goal is insulation for temperature, then go with spray foam. If you want to save money go with fiberglass or cellulose. If you want to mitigate sound, this is a different conversation. The opera singer's results are not typical and you cannot really depend on any of these insulations to truly mitigate sound beyond a moderate amount.

Ooh, "guy" with cat vs. opera singer.

Guywithcat, you don't know your ass from a hole in the ground. Whatever it was, it was Fiberglass and it was blown in and not installed in panels. I was told it was "foam." And it worked. Don't you have better things to do than demonstrate your ignorance?

Go play with your pussy, moron.

I had sprayed foam (sprayed on as a liquid, expands slightly, dries solid) done in ceiling, wall, and foundation crawl space areas in a house upstate, and it's great stuff. Provides excellent insulation, and some sound deadening properties (though if you're really trying to solve a sound issue, there is significant additional work to be done). It also solved the problem of mice and bugs getting in through the foundation walls.

Potential problems:
*It's more expensive, and not something to try to cut corners on (it's very messy, so you want a professional installer who isn't a slob, and if not done right, doesn't provide the right R value).
* If you're filling wall and ceiling spaces, all wiring and plumbing must be installed before spraying.
* You will never be able to snake a new wire through the foamed walls if you need to make later electrical changes.

Given that energy costs are unlikely to drop, I felt the expense would be well offset by the long-term energy savings.

You go, fieldschester!!!!!

we did pink batts on an exterior wall......wish we did spray foam. The only issue is its such a small job....probably wouldn't have been worth the setup/tear down....

what foam insulation gives you is an air seal. the R-value is only 7 per inch with closed cell foam, but the air seal is what stops noise and temperature intrusion.

the other option could be poly-iso board with foam around the edges if you want to save. Poly iso is basically sheets of pre-formed foam that can be cut and molded. cheaper, more work.

What's worse than a girl with cat? A guy with a cat? PATHETIC.....................
