Injection Foam Insulation


Hi all,
I own a condo in Manhattan (new construction, 1 bedroom on the 3rd floor of an 8 story building with 28 units) & I am looking into adding insulation as the developer used the bare minimum! Anyway, I'm looking at two products
1) Inject-a-seal http://www.injectasealfoam.com/downloads.html
2) Tripolymer http://www.injectionfoam.com/technical_data.php
Has anyone had any experience with either product; or can anyone look at the MSDS sheets & offer their thoughts as each company claims its product is better than the others & as I'm new to this & do not fully understand the specs I'd appreciate any help anyone can offer.
Thanks in advance!

PS

I think I somehow accidentally sent this post to the webmaster as feedback on my 1st try & I apologize!!!!!

6 of one half dozen of the other. One claims an R value of 5 per inch the other claims 5.2. Five per inch is pretty much standard for extruded foam. I doubt the .2 would make an appreciable difference. I would be looking into the cost vs benefit of adding insulation to a 1 bedroom that already has minimal insulation. Perhaps your currrent insulation just needs to be air sealed better. As with any contractor, figure out which installer has better references etc and go with them.

Injection Foam Insulation


Thanks Jim,
I hate to be a pest but one other area of interest for me is fire prevention ability. I didn't understand how two such similar products could make such different claims. Tripolymer's site says it improves a walls fire rating while Inject-a-seal's site says it neither adds nor detracts from a walls fire rating (yet the inject-a-seal salesman I spoke to said it does increase the fire rating) how does one go about discerning what is true & what is BS?

Thanks again for taking the time to post a reply.

Notice the flame spread and smoke dev. ratings. Also one is 10 perms and the other 15-16 perms for water vapor. Have them add a vapor barrier paint afterward at the exterior walls unless sprayed 8" thick. http://www.kwikbuildpanels.com/pages/article_facts.html

Be safe, Gary
