Random ask - anyone in central PA have experience with installing spray foam? Freezing in my office again (sits over a garage) - so I'm on the hunt for an installer.
Surface mount only.Works great. Only drawback would make any future electrical or plumbing work extremely difficult where the foam resides.
I wouldn't do it. The substrate and the chemicals have minimum temps which are difficult to hit in the winter. Cellulous under your floor (above garage ceiling) would probably be cheaper and you can do it now. The other issue is the air leaks at the kneewalls (I'm assuming your office is a truss cavity and cold air getting underneath the floor from the sides.
You could probably install the blocking yourself yourself by cutting pieces of foam and using SPF kit to set it. I work in a third floor poorly finished attic and I can sometimes feel drafts coming in from bottom of the walls. Right now I'm almost sweating because we had to convert the space into one large by-pass damper for our zoned system.Thanks - I think you hit the problem. I had rockwool installed in the garage ceiling a few years back. It's didn't make much of a difference unfortunately.
I was thinking spray foam to seal the knee wall and overhang, but wanted to talk to someone before I wasted a bunch more money.
Sorry what's SPF kit? (My google searches return sunscreen).You could probably install the blocking yourself yourself by cutting pieces of foam and using SPF kit to set it.

Looks like the new model is 1000w only? oops.I think I would buy one of those radiant heat dishes and aim it at myself.
cost less than 7cents an hour for me on low.. and high will melt you out of your chair at 5ft.
Yeah - I had read that some installers could botch the mix, and that it off-gases while it cures. (I watch a bit of Mike Holmes, and it seems popular in Canada). That was the reason I held off the first time - plus is was cold, and the contractor fit me in.In a living space, I would not use foam. Too many variables, specially when it comes to mixing the chemicals, if the installer gets the mix wrong, it will be a disaster and can even be dangerous to occupant health.
Use fiberglass bats and blown in insulation. These are proven and have no health or air quality risks.
You can buy a spray foam kit at HD, Lowes, Grainger, etc.. Just cut the rigid foam to match the floor joist spacing and tack it in with the spray foam. Otherwise you gotta pile up the insulation above the depth of the floor joistSorry what's SPF kit? (My google searches return sunscreen).
Last time I tried to build a foam "cover" for my attic access it was a disaster. The adhesive I used wouldn't stick, and ended up using metal duct work tape. (I later learned that using the wrong glue could melt the foam). It was a mess - wife was pissed foam shavings everywhere. I measured wrong, and couldn't figure out how to cut the foam. (I had to cut it in the home depot isle just to get it home). So my insulation DIY game is sadly limited, to say the least.
Thanks...appreciate it.You can buy a spray foam kit at HD, Lowes, Grainger, etc.. Just cut the rigid foam to match the floor joist spacing and tack it in with the spray foam. Otherwise you gotta pile up the insulation above the depth of the floor joist
I had a heat pump installed a few years back and it made a big difference, but the floor is still cold in January / Feb.I think I would buy one of those radiant heat dishes and aim it at myself.
