Spray-in Foam Insulation?
Question:I was wondering what the pro's opinions are on using spray-in foam insulation. I would be using it to insulate concrete basement walls between 2x4 stud walls that I framed. I have about 120 feet of 8' wall to insulate.
Some websites I visited recommend having this professionally done. I have also located a couple sites that sell DIY kits. Two of these are Tiger Foam (www.tigerfoam.com) and FoamPower HandiFoam (www.foampower.com).
Anybody have experience with the DIY foam kits? Is spraying the 1" layer sufficient to drywall over? Thanks for any info!
Answers:
I work for one of the manufacturers of DIY foam kits and I can tell you that we have sold numerous units for this application. As a matter of fact, our video was shot using a basement wall as the substrate. Go to our website and view it...

1" thickness will give you an R factor of 7.7 of the non-fire rated foam, and 6.5 of the fire rated foam. This will reduce condensation and provide you with some insulation value. However, the Dept. of Energy recommends R-11 to R-19 (depending on the zone and the type of heat). So you would either need more foam or finish off the foam with another (less expensive) type of insulation material. The 1" of foam would provide the monolithic seal you are looking for.
Our product is avaialble through distributors. One of them sells on-line at
www.bestmaterials.com and another currently has product on ebay at an excellent price. Look Up item Numbers 180117375385 for our System 15 and number 180117373134 for our System 50.
Also, so you know, Tigerfoam, Betterfoam, Fomofoam, Powerfoam, Foampower, these are all the same people. This company is websites and a warehouse - they are not the manufacturer. The manufacturer is a company named Fomo Products - look up the website - you will see the product looks the same but the company addresses are different. And be careful with what they say you can do with the foam - - get a second opinion.
I hope this information is helpful for you...
dont really understand why you are insulating basement walls. they are concrete and underground so most of your warmth is not lost in this way, most of your heat is lost threw windows and your attic. most people finish concrete walls by attaching 2x4's to the walls and sheeting over with sheetrock. there you are done no insulation required.
