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
