This, in itself, is a huge benefit to the environment. These splines can be old lumber, engineered lumber products like I-Joists, strips of OSB called surface splines or even cam locks, which work like little deadbolt locks pinning one panel to the next. The various properties of these different splines can determine and alter the panel's stiffness. This type of engineering allows the panels to be used at different spans or under different loads. SIPs have been used successfully in virtually every conceivable climate and load condition in the world, according to Tracy.
SIPs are fully compatible with any floor or foundation system.
Once the floor is finished, the walls are ready to be tipped into place. SIPs produce true vaulted, or cathedral ceilings, and, because of the rigid insulation used in SIPs, this cost-effective space can be used as a second story or loft, since they are considered one of the most energy efficient ways to construct a home. Although exterior walls usually don't contain water lines, plumbing vents can go through SIP walls with a small amount of preparation by the manufacturer or builder, depending on local building code requirements. After these trades have had their day, panels may be finished with drywall or plaster inside, and any exterior surface, such as brick, stucco, siding, or stone. To be sure SIPs are manufactured under the most stringent of standards, each SIPA Manufacturing member is required to maintain an independent third party quality assurance program in their plant or factory, according to Tracy.
