That knife works well...used one this weekend on ICF wiring. After
looking at the hot knife, I wondered if a soldering iron with a piece
of 10 gauge copper wire wouldn't do the same thing...never tried...mabe
I will.

If you go the glueing route...you might want to check out their
foam-2-foam adhesive...just don't get it on yourself...DAMHIKT I must
of used 5 cases this summer while building my new home. It's truely
amazing stuff. Much like great stuff, but not the same.

Another source for the foam adhesive is:

I've not used this brand, but Windlock says on their site that they
will only sell to "qualified" contractors, FWIW.

Good luck,

Darwin

Hey,

Does anyone have any ideas on how to cut a 3-inch wide and 1-inch deep
trench into the face of a panel of EPS foam insulation?

It should travel vertically up and down the 8-foot high face.

Any ideas welcome.

Hot wire or hot knife is what is done on job sites. You can use a soldering
gun and a template to guide it.

Open the window and put a fn as it will stink and smoke a bit.

You can use woodworking tools, but then you will have dust all over.
