SIP Panel Engineering

Structural Insulated Panels, commonly called SIPs, were first introduced in the 1930s and have evolved into an economical and energy efficient means of building. Panels are made with a variety of skin materials (OSB, treated plywood, fiber-cement board, or metal) that sandwich rigid foam insulation. Structural insulated panels (SIPs) are a high performance building system for residential and light commercial construction. The panels consist of an insulating foam core sandwiched between two structural facings, typically oriented strand board (OSB). SIPs are manufactured under factory controlled conditions and can be fabricated to fit nearly any building design. SIP Panel engineering save time and money because they are framing, sheathing and insulation all in one. Strength is another advantage when it comes to SIP panel engineering. In terms of impact resistance, the SIPs we use are successfully lab tested for over 200 mph winds. The continuous bonding of insulation offers incredible strength and resistance to impact. Vertical and horizontal stress loads are tested to be up to two times stronger than conventional stud walls. SIPs resist up to 6,000 pounds per foot, which results in structures that are stronger, straighter, taller, and wider than with other construction means.

SIP panel engineering behaves similarly to a wide flange steel column in that the foam core acts as the web and the sheathing responds as the flanges. Under axial loads, the sheathing responds similarly to a slender column, and the foam core acts as continuous bracing preventing the panels from buckling. Just as wide flange sections increase in strength with increased depth, thicker cores result in stronger panels in compression and bending. Our SIPs are incredibly strong and lightweight and can reduce or even eliminate the need for an internal steel grid, making them preferable to building. Our SIP panel engineering provides engineers, contractors and building owners with unmatched flexibility for a broad range of applications.

Buildings constructed with SIP panel engineering generally costs about the same as building with wood frame construction when you factor in the labor savings resulting from shorter construction time and less job-site waste. Other savings are realized because smaller heating and cooling systems are required with SIP construction. Our team knows all the properties of our SIPs and can help you put together buildings of all sizes and structure types. We can offer technical assistance for your engineer or engineer the structure ourselves. Structural Panel engineering successfully addresses environmental forces such as hurricanes, tropical moisture, termites, etc. Each of our homes are designed with this and many more common sense attributes to reach our objectives: beauty, safety and economy.

For any structure designed with SIPs, Greenwood Engineering prefers to be the Engineer of Record, thus responsible for the entire structural design and analysis. Greenwood Engineering recognizes that SIP construction is not the same as stick framing, and different methods and designs should be used. Contractors and manufacturers familiar with SIPs are consistently pleased that our engineers understand construction methods that simplify SIP installation. But we provide more than highly advanced structural insulated panels. Simply tell us your job requirements, and we can help you design the best performance package for your facility, helping you stay on budget and on time.
