Structural Insulated Panels (SIPs) (also know 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 foam core construction eliminates the voids in walls common with standard fiberglass insulation. For these reasons, air temperature and quality are easily controlled which allows heating and cooling costs to be drastically reduced.

SIPs insulated panels can be used as walls, floors and roofs and can be combined to create a total construction system or they can be used as individual components such as using only wall panels but using conventional roof construction.  We can precut 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.

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.

What is Oriented Strand Board (OSB)?

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.
