Extremely strong, energy efficient and cost effective.

‍Supreme Insulated Panel Systems SIPS panels are available in 4’ x 8’ (1220mm x 2440mm),
4’ x 9’ (1220mm x 2745mm), 4’ x 10’ (1220 x 2050mm) and 4’ x 24’ (1220 x 7315mm)

Thicknesses of the panels vary from 2” (50mm) – 12.25” (312mm). The thickness of the panel
specified depends on application and desired thermal efficiency or R-Value.

How does the structural insulated panel design and fabrication process work?


The construction of a SIP home or commercial building begins with the construction documents. Once the construction documents are in the hands of an Extreme professional, they are converted to SIP shop drawings that give the dimensions of each individual panel. The shop drawings are reviewed by the builder, engineer, the building owner, and other involved parties. Once the shop drawings are finalized, the SIPs are fabricated and shipped to the job site for installation.

How strong are Structural Insulated Panels?

The structural characteristics of SIPs are similar to that of a steel I-Beam. The MGO skins act as the flange of the I-beam, while the rigid foam core provides the web. This design gives SIPs an advantage at handling in plane compressive loads. SIPs can be engineered for most applications.

What is the R Value of Structural Insulated Panels?


R-values for SIPs depend on the thickness of the SIP and the type of core material that is used. Static R-values, rate the effectiveness of insulating material. However, they do not accurately describe how products perform in a real world setting. When fiberglass or other types of insulation are installed, they are installed around structural members made of wood or metal which have a very poor insulating value. Field installed insulation materials are also prone to installation imperfections. The Department of Energy’s Oak Ridge National Laboratory has studied and tested the performance of entire wall assemblies in large sections. The resulting whole-wall R-value data reveals that a 4.5” SIP wall rated at R14 outperformed a 2”x6” wall with R-19 fiberglass insulation.
