Polyisocyanurate (polyiso) rigid foam insulation, also known as yellow foam insulation, is one of the best products for insulating atticsbasementsgarage doorsmetal buildings (pole barns), and more. With an R value of about 6.5 per inch (R-6.5), polyiso rigid foam insulation has a higher R-value than both extruded polystyren (XPS) and expanded polystrene (EPS) rigid foam insulation with R-values of 5 (R-5) and 3.8 (R-3.8) respectively. Ken Nichols Insulation provides polyiso foam sheets of various thicknesses and with foil, gray latex, or black felt facing.

There are many benefits to using polyiso rigid foam insulation boards instead of fiberglass or cellulose insulation including the fact that foam insulation board does not easily absorb water, it can create an air seal when using foil insulation tape, and it doesn't lose its R-value through compression like fiberglass insulation may. See our prices at the top!
