Enercept SIP Fire Rating

SIP Fire Rating

This home, located in North Dakota, caught on fire while the owner was on vacation. The walls were constructed using Enercept Structural Insulated Panels; they used trusses for the roof. Although most of the home sustained extensive damage, the exterior SIP walls remained standing with little damage.


Before Fire


After Fire


Enercept SIPs are included in the SIPA Fire Rating.

SIPA-Structural Insulated Panel Fire Performance

SIP Wall and Roof R-Value Charts
There is more to insulating than the R-Values of a wall…Building with SIPS means less air infiltration – no thermal bridging, and a more energy efficient home.


What are R-Values?

The measure of the capacity of a material, such as insulation, to impede heat flow, with increasing values indicating a greater capacity.

The overall R-Value for standard 6 ½” Enercept Wall Panel is about 25

  • 6″ SIPS wall panel has an R-Value of about 25
  • 10″ SIPS roof panel has an R-value of about 40

Enercept uses expanded polystyrene (EPS) for it’s insulating core.   EPS has an R-Value of 4 per inch of foam.

Code Approvals


The International Code Council (ICC) was established in 1994 as a non profit organization dedicated to developing a single set of comprehensive and coordinated national model construction codes. The ICC is a merger of Building Officials and Code Administrators International, Inc. (BOCA), International Conference of Building Officials (ICBO), and Southern Building Code Congress International, Inc. (SBCCI). These organizations previously developed three separate sets of codes and have now combined creating the International Code Council (ICC) and developing codes without regional limitations.

Enercept has been tested and meets their requirements – see ES Report #ESR-1780 ICC Evaluation Service, Inc.


Enercept 8′ wide Jumbo Panels have been tested and meet the requirements of NTA, Inc.  Enercept Jumbo Panels are included in the Structural Insulated Panel Association (SIPA) Report.  You can download a copy of Enercept’s NTA Listing Report here:  ENR012012-21 Listing Report 2017-03-09.
