The Murus Company, Inc. has been manufacturing Structural Insulating Panels (SIPs) since 1987. Located in scenic Mansfield Pennsylvania, we take great pride in our commitment to quality and to the provision of excellence in product and workmanship. Murus uses only the highest quality materials and the most advanced technologies to bring you the absolute best in Structural Insulating Panels. Polyurethane, EPS, and GPS structural insulated panels for walls, roofs and floors in residential and light commercial construction applications, in various lengths, skin material configurations, and thicknesses. Murus Structural Insulated Panels (SIPs) are ideal for Green Building projects, as they are environmentally friendly and are proven to significantly reduce heating and cooling expenses. SIPs consist of a rigid foam insulation core that is bonded between two layers of rigid sheathing, referred to as "skins." Murus SIPs are manufactured with rated skins and are capable of supporting axial and transverse loads. Oriented strand board (OSB) is the most widely used skin material for structural applications due to its competitive cost, availability of sizes, and volume produced. OSB is produced from fast growing, renewable trees which reduce the strain on the nation's forests. Murus SIPs offer superior insulating values- better than any other commonly available insulation, and better than other building systems that are plagued by thermal bridging, and breaks, and air infiltration. Our system provides more R-Value per inch and virtually eliminates energy robbing air infiltration. Our system reduces wall thickness and reduces the cost of wider plates and nailers, window and door extension jambs, and nets more floor space. Murus SIPs create the most comfortable structure possible, and can save 50 percent or more in heating and cooling costs over conventional construction. From your very first contact with the Murus staff, right through delivery and installation of our structural insulating panels, we offer outstanding technical support and professional client services. Murus envisions a time when Structural Insulating Panels (SIPs) are the conventional construction method of architects, design professionals, engineers, builders, and home buyers. We are proud to stand at the forefront of this movement. SIPs are rapidly finding their way into the mainstream building community because of their time-, cost-, and energy-saving value.
