OSB SIPs
Structural Insulating Panels (SIPs) are a composite building material consisting of a panel of insulating material, usually foam, sandwiched between two wooden layers. The wood can be oriented strand board (OSB) or plywood. Sometimes more exotic materials, such as sheet metal or concrete board, are substituted for the wooden layers. SIPs replace several components found in conventionally framed buildings including studs, joists and insulation. SIPs are most commonly used to construct exterior walls and roofs but may have other applications, such as insulated ceilings beneath conventionally framed roof truss systems.
Structural Insulating Panels have a history dating back to the 1940s when structural wall panels were first invented. Over the years the technologies and materials incorporated in SIPs have improved. In addition, computerized CNC cutting machines allow SIP panels to be factory manufactured and then cut to the exact size needed for construction, providing a certain level of prefabrication not seen in conventional construction.
Panels for Walls and Roofs
Homes using SIP panel construction tend to have a very tight envelope. Air infiltration, or draftiness, is eliminated and the walls themselves have a very high insulating quality. SIPs may cost more than conventional framing, but because they bring extreme energy efficiency to buildings, they lower operating costs. SIP panels are often combined with post and beam construction where the panels drape the frame creating an extremely durable and energy efficient structure. Trilogy Partners utilizes SIP panels in all of its Timber Frame and Post and Beam homes.
