SIPS Panels are typically joined using a specialized insulated spline that extends the entire length of the panel connection. This spline is not only insulated with EPS to prevent energy loss but also reinforced with an OSB layer for added strength. The design of these splines is crucial in maintaining an airtight seal, thus eliminating cold bridging where heat could potentially escape. This method of connection is highly efficient, particularly when compared to traditional timber frame houses, as it can greatly diminish the amount of energy lost from a household, potentially leading to reduced energy expenses.
