SIP construction is used for new home construction, commercial buildings and on the farm use in storage, shop or office buildings. Structural Insulated Panels join high performance rigid foam insulation to Oriented Strand Board (OSB) or plywood. The thickness of foam is adjusted to increase R-Value. Regardless of the final use, building with structural insulated panels gives the owner a high-performing energy efficient building. An EPS insulated panel walls are up to 15 times more airtight than stud walls. SIP construction offers great design flexibility with larger clear spans and high vaulted ceilings.

Our pre-engineered buildings are used for livestock, equestrian, poultry, dairy or storage needs. Post frame buildings can incorporate long span trusses to provide large open areas giving you flexibility for real world use. Our post frame buildings use laminated columns that are placed in direct contact with the ground or on concrete. These laminated columns are pressure treated with preservatives to increase their longevity. EPS posts carry a 50-year warranty. Whether you choose a post frame or SIP building, it is designed to provide a high value in ease and speed of construction, quality and durability of the final building.
