Fomofoam?

Since I have decided to use a spray in insulation for my new addition which consists of engineered I-beams 12 " apart I was wondering if anyone ever used www.fomofoam.com??? They have a DIY foam kit that comes complete and ready to use, I am not a rocket scientist by any means but I figured it might be worth a try. The addition is approx. 22 X 26 and I would be filling the I-beams from below (garage underneath, master bedroom/bath above) with the spray insulation.

Any help would be appreciated - experiences? Tips/tricks?

Not sure if I would be getting in over my head on this one especially since all the permits are in my name and the town inspectors are quite strict.

Thanks in advance,
Mike.

Installing foam from underneath the floor is going to be quite difficult. First the weight of the foam will cause it to fall down before it cures. Secondly it's doubtful if you're going to get good coverage. And lastly this stuff is not inexpensive. I would recommend you use some other type of insulation, however, if you really want to try this stuff, I'll tell you how I would attempt to do it.

I would staple up a bed sheet perpendicular to the I beams about 2 feet in depth. This will allow you to fill in between the I beams without the foam falling down. Then I would continue stapling up the bed sheet every 2 feet until almost all the garage ceiling was done. The last foot I would staple up the bed sheet and pierce it with the foam applicator in each cavity between the I beams to fill in the rest of the garage ceiling. You can do the same thing with cardboard but I like using the bed sheets better.

Also buy yourself a very large bottle of acetone (nail polish remover). If you get this stuff on your hands, you must immediately remove it with the acetone. If you count to ten and then attempt to clean your hands with acetone, it will not come off. It is mandatory you wear eye goggles, gloves and a hat. After you finish before you go into your home, change your clothes. You get this stuff on your furniture, floors or walls it's going to be there for awhile. DO NOT TAKE WHAT I'M TELLING YOU HERE LIGHTLY. If some drops on the garage floor, let cure and it will scrape up. DO NOT ATTEMPT TO WIPE IT UP. Even with acetone. Once you smear this stuff, it just won't come up. You are better off letting it cure and then scraping it up. Good Luck.

DIY Foam?

Resercon,

Thank you for the response, I figured it would not be easy to apply the foam myself, all the companies state they are DIY kits but everything is always more complicated than the instructions.

What would you suggest for a DIY job on the I-beams? I posted another message about it but never really got any responses about how to do it correctly. Since the garage space is unconditioned I assume the vapor barrier needs to be up against the floor first and then the insulation added underneath. The beams are are only 12" apart and the cavities in between are pretty deep. I thought about stapling up poly as a VB but it would be almost impossible to get a good seal going in and out of each beam individually, the floor above is already glued and nailed down with new framing on top of it so it is impossible to lay the VB down above it.

I do plan on putting real hardwood floors down 3/4 ", could I put the VB under that and still insulate from underneath? If so what would be the best material to insulate with? They do not make batts that are for 12" OC that I know of and there is nothing to hold the insulation up until the sheetrocking is done.

Any comments/thoughts would be appreciated.

Mike

If you use foam you don't need a vapor barrier. In fact the foam is a qualified vapor/air barrier.

Building code in New Jersey mandates that garage ceiling be sheet rock that is fire rated. Check with your local building inspector for what is acceptable.
