New Comprehensive Manual. This Guide provides clear and easily accessible engineering design basics for structural insulated panels (SIPs). The manual captures SIP industry standards as developed and reviewed by longtime SIP professionals. Support for Engineers and Architects. This Engineering Design Guide is specifically tailored to support Design Professionals who are relatively new to SIPs. The Specification and Design Examples formalize and simplify design procedures for experienced SIP engineers and architects.
PART 1. Design Specification. 60+ pages of definitions, equations and derivations.

PART 2. Commentary. Background reference for the Design Professional seeking further understanding of the basis and limits of the Design Specification.

PART 3. Design Examples. Typical, practical applications of the Design Specification parameters.

Examples are written up in the manual, and interactive online versions are available for your own calculations (no need for downloads).
More Applications for SIPs. This new tool makes it easier to design with structural insulated panels for a wide range of structures. The Design Guide helps Design Professionals access the innovative strength, span, and loading characteristics inherent to SIPs while taking advantage of the building system’s simple and fast installation even in complicated multistory commercial structures.
