Company Overview

SIP Supply since 2003SIP Supply, LLC is a polyurethane (PUR) panel technology patent holder for high-quality structural insulated panels and owns the premium brand, Greenix®.  We have been serving the construction industry, government and military sectors since 2003.   A Greenix Panel provides premium thermal efficiency, structural integrity and design flexibility.

SIP Supply's specialty is fulfilling large volume orders by utilizing our network of high-production manufacturing facilities in Georgia, Tennessee, Mississippi, Missouri, Kansas, Virginia, Minnesota and California, and yet we continue to remain price competitive for single dwelling projects and Greenix Homes SIP Kits.

SIP Supply was the first company in the industry to produce an AIA-accredited continuing education course for polyurethane structural insulated panels, "The Features, Benefits & Applications of Building with Structural Insulated Panels (SIPs)." The course can still be purchased at our website.   

Our affiliation with the Mil-Spec Group provides government clients with the ability to fulfill their obligations to contract with companies designated as "minority-owned" and/or "service-disabled veteran owned small business."  SIP Supply and Mil-Spec Group work together closely to ensure the most comprehensive approach possible to meet client needs.
