Rigid foam is a type of foam that is stiff and does not easily compress, commonly used for insulation or structural applications. Self skinning foam, on the other hand, is a type of foam that forms a dense, durable exterior skin when cured, making it ideal for applications where a smooth surface finish is desired, such as in furniture or automotive parts.

What is the difference between rigid polystyrene plastic and expanded polystyrene?
Rigid polystyrene plastic is a closed cell of light weight, rigid & foam plastic that is derived from petroleum and natural gas by products. It is hard plastic in one word. This is used to make plastic containers and insulators. On the other hand, expanded polystyrene is derived by expanding the regular foam molecules by 50 times their volume using a blowing agent (pentane gas). This is used to make packaging materials.

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.
