Statement: Murus understands that not all structural insulated panels (SIPs) are created equal. Not all companies enjoy the Murus reputation for quality, innovation, and service. More and more architects, engineers, builders, and homeowners are turning to Murus SIPs—the most technologically advanced building system available. Murus structural insulated panels (SIPs) create a continuous, whole-wall system that prevents energy-sapping thermal breaks found in traditional framing. Murus SIPs are so highly energy efficient that smaller, less expensive heating and cooling equipment may be used for further savings. Structural Insulated Panels are available with many different r-values.
