It is the same as the gray. I used a router and jig to cut my patterns in homasote -- which makes a substantially bigger mess than just cutting it with a saw or blade. If I need more I will hang plastic shower curtains around my work area and wear a full face mask to cut and clean up. There is a lot of misinformation about extruded pink or blue foam panels. In free space they don't offer much of a sound barrier. But using them on top of a dense surface like plywood does absorb a lot of sound.
Thank you Iron Horse, Menards isn't in Maine, but others carry the 440 board here. $30.00 per board now, I haven't bought any in over 20 years. Cutting Homasote has never been an issue for me, just wanted to make sure I order the correct product.
