Factory-made panels
SIPs are fabricated under factory-controlled conditions and configured for the project’s planned layout, openings, and connections.

EPS Buildings
Big Twig Homes is an authorized EPS dealer. EPS building packages cover commercial, agricultural, equestrian, shop, storage, multi-family, and related applications. Start with the use—then the written quote names the structural system, because not every EPS building uses SIPs. EPS proposals take about 4-5 weeks.

Start with the purpose
The use informs the design.
The quote defines the system.
EPS organizes its building options across residential, commercial, cold-storage, livestock, shop/storage, and multi-family applications. Big Twig helps define your material needs and coordinate delivery. Your builder manages construction and its schedule.
SIP building education
When a SIP system is the right fit, design the whole envelope.
Structural insulated panels are a high-performance building system made with an insulating core between structural facings. SIPA describes their use in residential and light-commercial construction; EPS offers SIP products alongside other building systems. The applicable quoted system is selected for your building.
Design and engineering
Panel layouts, structural support, shop drawings, interfaces, and the selected assembly need to be resolved before manufacturing.
Handling and installation
Access, unloading equipment, foundations, dry storage, panel lifting, sealing, and assembly sequence should be coordinated with the builder.
Ventilation and systems
A tight envelope needs planned ventilation and mechanical design. Heating, cooling, moisture, and trade coordination are whole-building decisions.
Educational context from the Structural Insulated Panel Association and SIPA design guidance. This is general information, not an EPS system specification, engineering approval, or SIPA endorsement.

01
Commercial & community
Retail, office, hospitality, worship, and education spaces. Start with the dedicated commercial buildings page, then share occupancy and layout needs.
02
Industrial & governmental
Discuss the intended use, equipment, clearances, and project requirements so the applicable engineered package can be evaluated.
03
Agricultural & equestrian
Livestock, horse facilities, and farm buildings. Explore horse barn kits and insulated equestrian buildings, then coordinate ventilation with your professionals.
04
Shop & storage
Equipment, workspace, or storage applications. EPS offers solid-core insulated, post-frame, and ladder-frame options; the quote identifies your system.
05
Cold storage
Coolers, freezers, and temperature-controlled spaces require a coordinated building envelope and mechanical design for the intended use.
06
Residential & mixed use
Single-family SIP homes, multi-family and duplex packages, cabins, and home/shop designs. A shouse is a home/shop application; its residential and shop assemblies may differ.

FAQ
Questions people ask before they request a package estimate.
What is an EPS building package?
An EPS building package is a material package for commercial, agricultural, equestrian, shop, storage, multi-family, and related applications. Big Twig helps define your material needs and coordinate delivery. Your builder manages construction and its schedule.
Do all EPS buildings use SIPs?
No. Application and structure are different decisions. A workshop, barn, or commercial building does not automatically use the same SIP assembly as a home. EPS describes insulated, post-frame, ladder-frame, and other project-specific solutions. The written quote names the system for your building.
Who constructs an EPS building?
Customers select and hire their own builder. Big Twig supplies the material package, design guidance, technical support, and delivery coordination. Your builder manages construction, trades, permits, and the completion schedule.
What should I start with—commercial, a horse barn, or multi-family?
Commercial buildings, horse barns, and multi-family packages have dedicated pages. Use this hub to compare applications, then open the line that matches your project. Shop, storage, cold storage, and mixed-use buildings can also be discussed from this page.
How do I request an EPS building estimate?
Use the free-estimate form and choose EPS Buildings as the product pathway. Describe the intended use so we can discuss the right quoted assembly. Big Twig does not publish a universal square-foot price.
