Questions
EPS buildings questions
Updated September 2026
What is an EPS building?
EPS stands for Energy Panel Structures. An EPS building combines structural insulated panels (SIPs) with post or steel framing, and each one is custom designed and engineered for your project.
The result is a very energy-efficient, strong building with a finish-ready shell.
What can you build with EPS?
EPS engineered packages range from single-family and multi-family homes to commercial cold storage, livestock buildings, shops and storage.
Is State Line an authorized EPS dealer?
Yes. State Line Construction is an authorized EPS dealer, so we can quote, order and build EPS packages for customers in Iowa and Nebraska.
Are EPS buildings worth the higher cost?
EPS usually costs more up front than post frame, but its insulation lowers heating and cooling costs for the life of the building. It makes the most sense for homes, offices, shops you heat and cold storage.
We will walk you through the numbers for your project before you decide.
