Structural insulated panel Alternative to wood light frame Closed panel system combines structure and insulation Manufactured to specifications in shop and delivered to site ready to assemble Reduces on site construction time, allows for the use of less skilled labor Relatively small market share

Basics of panel system Expanded polystyrene core Extruded polystyrene (XEPS) and polyisocyanurate (ISO) may also be used 1/2 inch plywood or OSB facing each side Panel laminated to insulation core Structural grade adhesive Applied under pressure Used primarily in building envelope Proprietary product - each manufacturer specific details Manufacturer develops shop drawings based on architectural drawings Fabricated after approval by architect and constructor
