EPS (Energy Panel Structures) has been in business since 1981 and is now considered one of the best SIP (structural insulated panels) manufacturers in the US.
Since their move to Graettinger, IA in 1988, the company has expanded its manufacturing space three times.
Today, their main manufacturing facility totals 110,000 square feet on 8 acres.
EPS, which is 100% employee-owned, expanded once again in 2010 and 2013, purchasing manufacturing facilities in Missouri and New York.
The company offers a wide range of pre-engineered home floor plans, which all feature their structured insulated panels (SIP) product.
Energy Panel Structures Build Quality
The Structural Insulated Panels (SIPs) offered by EPS are what set the company apart from others. These high-performance building panels are used in walls, floors and roofs of residential homes.
SIPs consist of three layers:
Oriented strand board (OSB)
Closed-cell rigid foam plastic insulation
Another layer of OSB
The thickness of the foam can be adjusted to increase the R-value quickly and easily.
SIPs have a higher base R-value compared to conventional framed walls (24.7 vs 13.7). And unlike fiberglass, which can lose up to 80% of its R-value when exposed to moisture, SIPs shed water and maintain their R-values.
Thermal performance is not affected by temperature changes. In fact, R-values actually increase as temperatures drop.
Extremely low air levels of air infiltration allow for better mold and mildew prevention. SIP homes are less prone to dust mites and mold growth. It’s easier to control humidity levels, and with SIP panels, there’s no offgassing or formaldehyde to worry about.
EPS buildings, thanks to SIPs, provide long-lasting insulation that maintains its R-value for the lifespan of the home.
EPS Floor Plans
EPS has a wide variety of floor plans to choose from, but because they’re a custom builder, you can also have a custom floor plan created exactly to your specifications.
Here’s what each home package includes:
EPS R-26 SIP wall system for house and garage walls
Framing lumber for interior division walls
Engineered roof truss kit
1/2″ OSB roof sheathing
Structural Insulated Panel roof system for select designs only
Extra options are available, such as:
Premium OSB subfloor options
Floor system with 16” open web floor truss and 3/4 tongue and groove decking
Basement walls 8’ tall (EPS R33 SIP wood foundation system)
EPS R26 garage frost foundation
Home packages do not include:
Site and foundation work
Doors and windows
Essentially, EPS is supplying the building, but you have to take care of the site work and finishing touches to make your home habitable.
This is common with most pre-engineered building suppliers, and this arrangement gives you more control over the site work and the costs of prepping and finishing the building.
