SIP Construction

Structural Insulated Panels or SIPs are an option when building with Eaglecrest Homes.  SIPs can be used for wall construction, roof construction, or both.  SIPs can be used with or without the structural framework of a timber frame home, as they are incredibly strong on their own.  Structural Insulated Panels are available in jumbo sizes up to 8’ x 24’, so they speed construction.

SIPs are very energy efficient as they significantly reduce thermal bridging that is common with a “stick-built’ wall system.  They provide a super tight envelope, keeping your energy dollars inside your home.  R-Values vary based on the core material and thickness.  SIPs typically have an inner and outer “skin” of 7/16” OSB, adhered to a core of insulation.  The core thickness can vary from 4-5/8” to 11-3/8”, depending on the core material.  R-Values range from 15 to 52, but are an understated measure of thermal efficiency.


Construction Expertise

  • Eaglecrest Homes’ partner Tom Waterloo built his first SIP home in 1988, and has been involved in the construction of more than thirty SIP homes over his career.
  • He is certified by SIPA, the Structural Insulated Panel Association, to instruct Architects for continuing education credit.

Construction Process

The process of building with SIPs is similar in many ways to conventional construction.  Two key differences are lead time and construction time.  Lead time can be longer, in as much as SIPs are pre-engineered.  Unlike “stick” construction, you can’t call a lumber company and have material delivered the next day.  However, because the SIPs are pre-cut to size and shape at the manufacturing plant, and shipped to the site ready to install, the on-site labor and installation time is cut.
