Rmax Durasheath®-3 is an energy-efficient thermal insulation board composed of a closed-cell polyisocyanurate (polyiso) foam core bonded to inorganic polymer-coated glass fiber mat facers on each side. It offers energy performance and superior durability and is intended for use in exterior walls with stucco veneer, concrete sandwich panels, and many other building envelope applications, including those where an impermeable foil-faced product is not desired.
