This year, ‘resiliency’ emerged in the building landscape as more than a buzzword. Many regions around the world are increasingly subject to the rigors of various impacts, including extreme weather, population shifts, disease, power or communication disruptions, and financial shocks.
Insulation is a critical component to specify when designing a functional, cost-effective, and energy-efficient building. One method to insulate a building is by installing 50 to 152 mm (2 to 6 in.) of rigid foam insulation on the exterior side of the wall framing.
Plastic foams for thermal insulation have been available for more than 70 years. Extruded polystyrene (XPS) was introduced in 1943, followed by expanded polystyrene (EPS) in 1950, and polyisocyanurate (polyiso) in 1954.
