Although a newer product than polystyrene, it has caught on quickly due to its high efficiency and ease of use. Polyurethane is sprayed into each panel and makes a very tight fit which will add to the rigidity of the panel when it is new giving it a higher R-Value. Pressure-injected garage doors with polyurethane foam have R-values between R-12 and R-18.
