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). OSB is a vital structural part of the panel, making the panels superior to regular construction materials. 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. Building with SIPs will save you time, money and labor.


R-Value is the measure of the capacity of a material, such as insulation, to impede heat flow. Higher values indicate greater capacity. 


Panels supplied uses EPS (expanded polystyrene) for the insulating core, which has an R-Value of 4, per inch of foam. 


One must consider the 'whole system' efficiency to obtain a more accurate R-value.

BENEFITS of SIPs Construction
  • Energy cost savings > 50%


  • Build 30% faster than other methods-reduction of frame-in time allowing accelerated interior finish

  • Optimal indoor air quality; significantly quieter indoor environment

  • Minimally 2-1/2 times stronger than stick frame 

  • Additional useable interior space

  • Wind rating up to 200mph with additional construction package

  • Full 360o thermal envelope with floor, walls and roof

  • Panels are manufactured in controlled environment for quality assurance

SIPS are a new invention

SIPs were first used in the 1930's. The current configuration was developed in 1950 and has only improved in quality and design through the years.

SIPs are too expensive

Comparing the overall applied costs by adding labor costs, energy savings, job site waste, and the cost of all material together, building with SIPs is comparable or less than traditional construction.

SIPs are only for simple, prefabricated designs

SIPs can be customized for almost any building design, including rounds ones!

SIP Panels are difficult to wire

Even an unskilled electrical apprentice can wire a SIP home quickly and easily using the factory installed electrical chases.
