ICC-ES Evaluation Report
ICC-ES ESR-5510.
Independent evaluation. Defined performance.

BOXWAY Structural Insulated Panels have been evaluated by ICC Evaluation Service for structural and fire-related properties under the applicable IBC, IRC and IECC requirements listed in ESR-5510.
What an evaluation report is
ICC Evaluation Service is an independent body that reviews building products against the International Codes. An evaluation report documents how a product was tested and evaluated, the values it achieved, and the conditions under which those values apply. Building officials use evaluation reports as evidence when reviewing permit applications.
For BOXWAY, ESR-5510 turns the panel system into something a code official, engineer or lender can look up and check, instead of taking our word for it.
