Polystyrene and polyurethane are the most common materials used in making foam board.
Foam board insulation is a great alternative to the very common fiberglass batt insulation that is in most of our homes.
These are panels of rigid foam sold in 4 by 8 foot sheets in a variety of thicknesses from 1 4 to 2 inches it is also sold in large bundled panels joined at the ends accordion style for use as an exterior sheathing material.
Rigid foam insulation uses one of three materials.
Insulated foam sheets are also used as an insulated sheathing underlayment for exterior siding.
