Kingspan’s versatile 300 Series Minor Rib panels are suitable for exterior applications in commercial and industrial buildings, as well as interior walls, partitions and suspended ceilings in cooler/freezer applications. The 42-inch-wide panels are available in 10- to 48-foot lengths and a wide range of colors and thicknesses (2 to 6 inches). The panel’s polyisocyanurate core is chemically bonded to non-permeable steel facings to provide continuous insulation and retain insulating values over time. R-values range from 16 to 49, and improved side joinery offers excellent foam-to-foam contact for full thermal seals. The exterior profile provides a clean, flat appearance and ensures excellent sealing of vapor barriers.
