Re: Spray Foam or Batts

Ok, I stand corrected, there is a DIY foam kit. Someone sent me a link to this.

So, it is available but up front cost is still expensive. Using their estimator, I estimated 240 SF (3x8x10). Came out to $931 for spray foam vs ~$140 for R-19 fiberglass.

I believe even the local hardware stores carry it. Our contractor got it through a big box store I thought. He used the stuff for our sunroom outside walls. It is expensive, but I think it's worth it.

Wow, yeah, that IS expensive!

In any case, regarding future wiring, if you'd be running new wires in from the top you could glue a raceway like this »www.cableorganizer.com/surface-r···ards.htm behind the drywall, with a length centered in every second or third stud cavity. As long as you decided to put your new drop right between the studs you'd hit the open side of the raceway.

I think it's cheaper if you get it locally. Ours wasn't nearly that expensive.

There are MANY DIY foam kits. Not sure how you estimated 240 SF as the OP didn't give any dimensions other than

The framing is 2x4 so not a huge amount of space.



which would rule out R-19 batts. On the other hand, foam is around R-7 per inch, so the 3.5" thick wall cavity would be R-24.5 if filled with foam versus R-13 with batts.

You're right, OP never gave dimensions. I was giving a cost comparison for X amount of wall space, I wasn't trying to give him a job estimate. You can pull those knickers out of your bum now.

Instead of throwing insults why not behave in a civil manner. Your cost comparison was missing in many details. This is not just about dollars. Foam accomplishes a number of things which batts do not including more R-value in the available space as well as the vapor issue. There are others as previous posters have indicated. Just looking at the dollars per cubic foot of insulation without regard to any other factors is totally worthless!

If the shoe fits, wear it. When you come across as pompous, as you still are, don't act so indignant when you get called out for it. I'm sure the OP is a big boy and can read through all the comments and make an educated decision by what everybody has posted. For some people cost is a major factor. I believe others have covered those "other factors" and will continue to do so. To single out my post and claim it is "totally worthless". Well played.

Before you make that purchase visit the EPA website about spray polyurethane foam. If you don't know what to prepare for this could be the most expensive mistake you could ever make. Also read what the CDC has to say about it. These products placed in untrained hands could place you in the ER for pulmonary distress.
