ABOUT ENERGY PANEL STRUCTURES 

EPS Buildings started when...

Energy Panel Structures (EPS) was established in 1981 when MacArthur Company took a different course after 68 years of making insulated pipe, and concentrated on a new product: insulated wall panels.  EPS' Structural Insulated Panels (SIPs) are high-performance building panels used in exterior walls, roofs, and floors.  The panels are made by sandwiching a core of either Expanded Polystyrene, or Neopore between two skins of oriented strand board (OSB).  Among other benefits, SIPs are up to 15-times more airtight than traditional construction, and help to deter insects and pests with Borate mixed in it's core.  EPS is 100% employee Owned and 100% Quality Committed.
