Environmental Practices

At Ultimate Construction, We Believe in Building Green in Order to Preserve the Earth’s Natural Resources

We strive to make our homes energy-efficient, to practice green building techniques, and to be responsible stewards of the environment.

We use superior products such as Structural Insulated Panel Systems (SIPS) to ensure that our homes and commercial spaces are energy-efficient and more comfortable. Our innovative designs and building practices help preserve the environment and protect our building sites by leaving nature preserves and wildlife habitats undisturbed.

EPS Structural Insulated Panels (SIPs)

SIPs Provide an Extremely Durable, Strong, and Energy-Efficient Building Option

SIPs are engineered panels used to construct walls, ceilings, and floors as a replacement for traditional framing lumber and insulation. They are easy to install, have higher insulating properties, and can lead to fewer drafts and a decrease in operating costs.

SIP usage reduces energy bills as much as 50 to 60 percent. Plus, structural insulated panels are extremely airtight and make it easier to control indoor air quality and heating, ventilation, and A/C systems.



Interior Comfort

People spend 90% of their time indoors — it’s essential that your environment remain safe and pollutant-free.

SIP homes offer superior air quality control, as the tight building envelope prevents contaminants and allergens from entering through incoming air. Controlling ventilation also filters out impurities and dehumidifies incoming air to prevent mold growth.



Exterior Style

Because an EPS home is built with Structural Insulated Panels, it offers plenty of options for exterior finishes. You can choose traditional wood or vinyl siding—or brick and stone. Exterior finishings not only add a decorative touch to your new home but also protect it from the elements over its lifetime.

General SIPs Construction FAQs

What are Structural Insulated Panels (SIPs), and how does Ultimate Construction use them?

Structural Insulated Panels (SIPs) are high-performance building components used in walls, roofs, and floors to improve energy efficiency and structural strength. Ultimate Construction uses SIPs to build homes and commercial buildings that are energy-efficient, durable, and faster to complete than traditional builds.

Are SIPs more energy-efficient than traditional framing?

Yes, SIPs are significantly more energy-efficient than traditional wood framing. Their solid insulation core helps eliminate air leaks and thermal bridging, leading to reduced heating and cooling costs.

Can SIPs be used for both residential and commercial construction?

Absolutely. Ultimate Construction uses SIPs in both residential and commercial projects, delivering energy savings, increased indoor comfort, and long-term durability.

How long do SIPs structures last?

SIPs structures are built to last, offering similar or greater longevity than traditional framed buildings. With proper installation and maintenance, SIPs buildings can stand strong for decades.

Are SIPs environmentally friendly?

Yes, SIPs are considered environmentally friendly due to their high insulation value, reduced construction waste, and potential to lower energy consumption over the life of the building.

Shouse Construction

Shed + House = Shouse!

For residential buildings, our post-frame and SIPs structures combine unmatched performance and value. Other building types cannot match Ultimate Construction ‘Shouses’ custom design—nor will they last as long or perform as well in extreme weather conditions.

We’re ready to get started on your building project!
