Blue Board as wall insulation

I plan to insulate my wood frame garage. Any issues with ripping 2" blue foam board (DOW) and friction fitting it between the 2X4 framing? Is it better to hold the edge flush to the inside or push back tight to the exterior sheathing? The plan is to heat as needed, especially when working on projects over the winter months. I do NOT anticipate keeping it at a constant temp. The interior finished wall will be 1/4 luan. The exterior is 1/2 sheathing, tyvek, and cedar clapboard.

You mean 2" blue rigid insulation ?
It is cut & inserted in wall must be tight
Or caulk any rough edges

Insulation is usually faster & easier

Blue board usually refers to drywall
