The insulating spray foam I have used is Touch ‘n Foam.
For this job, I have Professional System 200. It is made-up of a 2-component polyurethane spray foam system that is portable and disposable, good for an estimated 200 feet (or less), and dries in 60 seconds.
The kit includes 2 cylinders of components A & B, attached hoses, nozzles, gloves, safety glasses, wrench, O-ring lubricant, instructions and a video.
The company says it has an R-value of 5.4 per inch, is closed cell with no ozone depleting chemicals
That was a great vid. Timing couldn’t be better for me as I’m considering foaming my attic. Will done BG. Thank you.
Use a good respirator, not a paper mask. I hurt the next day for the little I did w/out my respirator.
