So homasote can be routered? Can it be precut on a table saw prior to placement? Thx

I'm suspect you could cut it on the table saw, but for straight cuts, the utility knife works well.  You just make a few passes and you have a clean cut with no mess.  I never actually tried to cut it with the table saw. Most of the Homasote was cut pretty much in place with minimal mess.

I will say that cutting 2" construction foam on the table saw is a bit dicey.   I tried that one day, and while it can be done, it tends to grab, makes for an interesting experience.
