I plan to use this in a project to create a insulation box for an attic whole house fan in the winter. Will this work?

I plan to use this to box in my whole house fan to prevent heat from going theough the fan louvers and into the attic. This is a big problem in cold northeast. I plan yo create a 36”x36l box with a cap and just glue it togther. Just taking the cap off in the warmer weather months. Will this work and any issues using in an attic space?
Asked by: VoidNY
I think it will. I'd use the adhesive made for foam board, and maybe add a few finishing nails, or something similar to hold it together, while the adhesive sets up.
