Anyone have experience, good or bad, with the guns Great Stuff offers for their foam? I'm looking at the Model 14, $55. Aluminum body, plastic can attachment receiver, supposedly replaceable nozzle. That's the gun that shows up locally.
I'll be doing foamed-in-place sheet foam to insulate the whole floor (from the drarwlspace) - 1500 sqauare feet - and about a third of the ceiling the same way. And lthen, of course, whatever uses come up after that.
And a question about the guns in general: I see pictures of the guns being used with the can other than upside down, but one thread here said that, like the rattle cans, they need the can to be upside down to work. Can I use the gun in odd orientations, like with the gun sideways?
