Structural Insulated Panels (SIPs) (also known as Stress Panels or Sandwich Panels)  have emerged as a unique alternative building technology for the construction of high-tech, energy-efficient building envelopes. SIPs insulated panels are constructed using a high performance rigid foam core laminated between two layers of Oriented Strand Board (OSB). This lamination is done under pressure with a commercial grade urethane glue.
The unique foam core construction of the SIPs panels eliminates the voids in walls common with standard fiberglass insulation, which enables air temperature and air quality to be easily controlled, drastically reducing the heating and cooling costs for the homeowner.
SIPs insulated panels can be used as walls, floors and roof systems. They can be used as individual components of the building, or combined they make a total building system that is highly energy efficient. We can pre-cut openings for windows and doors in our manufacturing plant, or cut them on site to allow for complete customization of your project. The panels are then delivered to your job site ready for assembly.

The idea of SIPs insulated panel construction is not a new concept. As early as 1935, The Forest Products Lab built the first in a series of experimental SIP’s homes. Then in 1952, Alden P. Dow built homes in Midland, MI. This type of building concept continues to increase in popularity.

What is Oriented Strand Board (OSB)?

OSB manufacturing began in 1981. OSB panels consist of layered mats. Exterior surface layers consist of strands aligned in the long panel direction: inner layers consist of cross or randomly aligned strands. These large mats are then subjected to intense heat and pressure to become a “master” panel, then cut to size. OSB, as a performance-based structural use panel, is recognized by all the major US model code agencies through the adoption of DOC PS2-92 Wood-Based Structural Use Panels.
