Structural Insulated Panel System Chapter 15
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
Structural behavior • Panel behaves like an I-Section under axial and lateral loads
Advantages of SIPS • Panelization eliminates insulation subtrade • Air retarders generally unnecessary • Reduced on-site waste • Energy efficiency
Limitations of SIPS • Electrical chases pre-routed, requiring careful coordination • Absolutely square foundation and panels required for successful installation • Potential for termite and insect damage to wood and insulation • Long term performance of structure depends on performance of adhesives
