A Structural Insulated Panel, or SIP, is a composite building material. It consists of an insulating rigid core sandwiched between two layers of structural panels, and is often used in floors, walls, and roofs for either residential or light commercial buildings.
SIPs were added to the International Residential Code, or IRC, in 2009. The code specifies applicability limits and production materials (core, facing, adhesive, lumber, screws, and nails). Section R610 of the 2015 IRC requires that all Structural Insulated Panels be manufactured under a quality control program verified by an approved third-party quality assurance agency. Each Structural Insulated Panel must be identified by a certificate of inspection or grade mark issued by the approved quality assurance agency as part of a certification program to ensure code compliance.
NTA can provide testing for:
Our ‘Engineered Design of SIP Panels’ white paper offers all the most current design practices for working with SIPs (you can read the Design Guide here). NTA is accredited by International Accreditation Service (IAS), under ISO/IEC 17025 to test, ISO/IEC 17020 to inspect, and ISO/IEC17065 to certify SIPs. In fact, the DIY Network chose NTA to perform SIP testing for the television series “Deconstruction”!
In 2009, NTA partnered with the Structural Insulation Panel Association, or SIPA, to design a comprehensive certification code report for their members. NTA can issue a report showing code compliance for your Structural Insulated Panel. While the IRC covers only SIPs used in walls, with a thickness of 4-1/2 or 6-1/2 inches and a span of 8 to 12 feet, NTA can provide alternate certification for SIPs used in floors and roofing, as well as spans exceeding 12 feet. Our SIP certification program is highly customizable (learn about our SIP Certification Program here). We work with and certify SIPs that utilize a variety of facing, core materials, and adhesive bonding systems. We offer additional code compliance testing and certification for:
