Buildings & E-houses
Modular E-Houses for Power Distribution, Analyzers, and Control Systems constructed from self-supporting Structural Insulated Panels (SIP) or with integral structural steel frames, available with packaged HVAC, pressurization, and purge ventilation systems.
get in touch
Our System Integration & Fabrication group constructs these custom building enclosures from powder-coated Structural Insulated Panels assembled on a structural steel base frame.
For small buildings, these panels provide an integral structural enclosure. Where required for larger buildings or unique project specifications, these panels tightly integrate with an independent structural steel frame or skeleton.
Our panels can be constructed in a range of thicknesses from 2″ to 8″ or can be sandwiched in multiple layers to meet the most demanding energy efficiency specifications.
Upgraded painting and coating systems, removable transoms and bulkhead panels, purged and pressurized HVAC for Hazardous Locations, and custom interior electrical systems are just a few of the optional design elements that our shop can incorporate into your building.
