Make sure that your builder knows how to protect spray foam. Otherwise you're putting a massive fire hazard in the walls. The reason I advocate against spray foam is that contractors are terrible on the whole. They do the bare minimum. So I don't expect them to treat the foam. Take hardi siding. You're supposed to flash behind ever joint. Most don't. So now you get water infiltration. Then you go to Hardi. They won't stand by the warranty because of improper installation. http://www.industrialproducts.com/industrial_products_blog/does-your-spray-foam-insulation-need-a-thermal-or-ignition-barrier/ http://www.industrialproducts.com/industrial_products_blog/d...

>Make sure that your builder knows how to protect spray foam. Otherwise you're putting a massive fire hazard in the walls. The drywall is the only barrier you need since it is the fire proofing for all your framing and insulation. Only when the spray foam is not protected is there a need to cover it with fireproofing. If it is in a location where there is no open flame then fire retardant is not necessary. Please educate yourself about spray foam from the following links. http://www.demilec.com/ http://www.demilec.com/ https://www.cufca.ca/ https://www.cufca.ca/ >The reason I advocate against spray foam is that contractors are terrible on the whole. I hope your advocating against all insulation because installing Fiberglass Bat Insulation is done improperly also. How accurate is the blown in insulation in the attic? We could advocate in not building houses at all because contractors are terrible on the whole. Maybe you should advocate that the consumer educate themselves so they understand what the difference between a good job and a bad job is. The biggest problem with contractors these days are people want to pay as little as possible. The contractor therefore has to cut corners (do the bare minimum)to make the job profitable which can lead to problems down the road where you might not have the R-Value you expected. When you nickle and dime people trying to make a living the results can be less than optimal and that goes for any industry. The benefits of spray foam are many, it can increase the structural integrity of a framed wall %200, mold and mildew free, not a food source for bugs or animals, better R-Value than traditional batting insulation or blown in and best of all it pays for itself and can significantly reduce your energy bill from DAY 1.

  I do most of my own work for this reason. Again, if you want it, you have to be there to supervise the contractor. You have to know what to look for. You have to keep them accountable. Essentially you are your own general contractor. Tuck into the Internet a lot.
