What's the best way to cut 1-1/2" or 2" styrofoam sheets? *I don't

Table saw works fine with any decently sharp blade. Did two 16' square
rooms a while back with 1 1/2" 4 x 8 foam board (green) sliced to 16"
wide to go between furring strips. Table saw has the standard Delta
dust collector, no mess in the shop. Cut edges were perfectly flat and
clean. The cut went about as fast as could be fed through the blade,
maybe took 10 seconds. For round access holes, the hole saw did well
enough. Based on that seems any sharp toothed cutting tool ought to
work fine.
