How do you install rigid insulation?

Cut panels of rigid insulation slightly smaller than openings. Fill in gaps around rigid panels with liquid nails or any brand of construction adhesive caulking that is compatible with stryrofoam (polystyrene) or polyurethane foam, depending on what type of rigid foam you purchased. I prefer polyurethane foam and seal the perimeter edges with Great Stuff spray foam or DAP latex spray foams. That way you don't have any heat leaks around the edges of the rigid foam even if the rigid panel is between warped rafters or studs.
