|Ready to assemble Structural Insulated Panels (SIPs)
Custom manufactured and fully fabricated structural insulated panels (SIPs) are provided to enclose, insulate and make weather tight your timberframe. These panels are made up of expanded polystyrene (like Styrofoam) sandwiched between two sheets of 7/16" oriented strand board (OSB). Insulspan the supplier we use takes your timberframe's 3D CAD drawings and with computer controlled machinery pre cuts the panels to exactly fit your timber frame. All window and door openings, roof hips, valleys, wiring and plumbing chases are precut. No cutting or sizing of the panels is normally needed on the jobsite. Panels come in sizes of up to 8ft by 24ft to minimize handling and joints. Installation of the SIPs with a crane takes from 2 to 5 days on an average size home depending on the complexity.
SIPs provide much more than a quickly completed shell. Think of how warm your coffee stays in a 1/8" thick Styrofoam cup. Now imagine what a solid sheet 8" to 12" thick on the roof and 6" thick on the walls will do to lower heating and cooling bills. There are very few studs or framing members in the walls or ceilings to wick the heat through. An Oak Ridge National Laboratory report proved that a SIP home can save up to 50% on your energy costs for life of the building compared to a standard home built to the current energy code.
