After much research I took the plunge. My first purchase ever was pallet full of 602 kits. I tackled a whole house built at the turn of the century. Had wormy chestnut logs for floor joists. So lots of gaps and uneven areas. There was near zero insulation in the home. I did a full cavity fill on every place I could put it. Wow what a difference, immediate results. We had purchased the home in Dec 2012 and by summer 2013 had spent about $2000.00 in fuel oil with the thermostat set at 50 degrees. Just warm enough to work on the building and keep the pipes from freezing. In the fall of 2013 , I installed the foam. It is now spring of 2014 and I have used $850.00 so far in heating and will probably need an additional $150.00 to complete the year.

I kept the house at 70 degrees this winter. Which was MUCH MUCH colder then 2012-2013 winter for my area. My estimate is $3000-$4000 I saved in 1 year. It is was very easy to hook every thing up and use. I really prepped the work site, so once I started I didn't have to move stuff. I sprayed 12 sets of 602's in one day. With a lot of time going to dragging the tanks up a ladder into the attic area. I already have another house that I plan on foaming and expect to complete in one day. Great Product, Great Service. Don't hesitate to buy it. You will be hooked on it for all your remodeling . No more bugs, mice, drafts...
