I live in New England.
I’ve got a basement window frame that my sump pump drain runs through. The inside of the frame is plywood, then there’s the sill gap, followed by mesh on the outside of the frame. A hole has been cut through the plywood and mesh to accommodate the 1-1/2” drain pipe.
Previous owner basically used a vacuum tube for the drain pipe, 1/4” plywood, and expanding foam as caulking. So am going to be replacing the pipe with PVC, as well as the plywood with 3/4” (coated for water resistance), and silicone caulk.
I’m looking to put insulation in the space between the plywood and the mesh screen. Should I be using styrofoam, fiberglass batts, or something else?
Thank you.

Wouldn’t that expose to insulation to the elements? Might help if we can see a picture?
