High-performance building

Extreme Wall Panels

Extreme Wall Panels 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. The result is a building system that is extremely strong, energy-efficient and cost-effective.

Extreme Panel Technologies has adapted and supercharged the SIPs technology to create both a product and process that yield superior performance.

  • Zero panel off-gassing
  • ‘Red list’ chemical-free envelope
  • Panels free of dyes, formaldehyde, and hydrofluorocarbons
  • Envelopes that are moisture, fungus, carpenter ant and termite resistant
  • Consistent and comfortable user interior temperatures with vastly reduced energy consumption
  • Elimination of Draft due to poor seal and gaps
  • Reduced building interior contaminant infiltration

A Extreme’s SIP walls replace stud and batt insulation construction, creating a structural, extremely energy-efficient building envelope. SIP walls have a continuous wood surface that is crucial for a solid nail-base for both exterior and interior finishes. Interior finishes such as cabinetry, moldings, flooring, and more can be installed much easier on SIP walls than stud walls due to the continuous attachment surface. This allows for greater design flexibility for cabinet makers and finish carpenters since they are no longer constrained to expansions ending with studs.

For Extreme, it’s all about performance and quality!

  • Always begin at a corner
  • Large spans don’t require truss systems​
  • Place the first panel over the bottom plate and flush to the exterior edge of the building
  • While holding panel approximately plumb, in and out on the face, plumb the outside panel exactly vertical and nail off both sides (it will stand up easily by itself at this time)
  • After placing the proper sealant on the seams, situate the panel on the other side of the corner over its bottom plate, tight against the first panel, and nail off (at this time, the two panels are not attached to each other)
  • Align and attach the panels at the corner
  • One panel will run long and the other panel will butt up against the previous one
  • The panels are then attached with “Big SIP Screws” through the longer panel (just inside the dimensional lumber placed in the corner) and into the dimensional lumber in the second panel
  • The big SIP screws are placed approximately 3″ from the top and bottom of the wall and then at a maximum of 2 ft on center, or per the engineered detail drawings for that particular job

R-Values for Extreme Wall Panels

Insulation is one of the key components of any energy-efficient home or commercial building.  With heating and cooling accounting for 50 percent of energy use in the average home, good insulation saves thousands of dollars in utility bills over the life of a home.

Insulation is rated by R-value, which measures a material’s thermal resistance.  An insulating material with a higher R-value forms a more effective thermal barrier between the outside temperature and the conditioned space inside the home. Research funded by the U.S. Department of Energy confirms that SIP walls provide more R-value than same-sized stud walls.
