At SIPS of America, structural insulated panel (SIP) systems are designed and built around customer requirements, making customization a standard part of its process.
Unlike many manufacturers that charge separately for window openings, framing, electrical boxes and other project-specific modifications, SIPS of America includes these features as a part of every project, allowing customers to receive fully customized panel systems without additional costs.
“Instead of relying on standard in-house plans, we design every panel system around the customer’s home plans,” says Mikey Mantle, sales manager and lead estimator. “Customization is where we excel.”
Electrical boxes are pre-positioned within each panel, with ¾-inch wire chases running between them to allow on-site electricians to pull wiring. The wire chases are fully connected between electrical boxes before the panels leave the factory, unlike many conventional panel systems, where electricians must cut or melt foam to create routing paths. The panels are manufactured using oriented strand board (OSB) skins in sections up to eight feet wide and 24 feet long. With individual panels covering up to 192 square feet, larger wall sections can be enclosed significantly faster than traditional framing methods.
SIPS of America injects closed-cell polyurethane foam directly into the panel to minimize voids, rather than gluing pre-formed foam to the OSB skins. The controlled pressing process increases foam density from two to 2.5 pounds per cubic foot, achieving an average R-value of 7.5 per inch. A six-inch wall panel delivers an R40 insulation value, compared with R25 for conventional EPS-based systems.
From Design Plans to Final Build
Each project begins with customers submitting their building plans. The company recommends allowing three months between placing an order and the required on-site delivery date. Based on the plans, it prepares a 3D rendering showing how the completed panel system will look, together with a total cost estimate, which serves as the contract price.

Once the pricing is approved and the project moves into contract, SIPS of America begins detailed panel engineering. Over the next four to six weeks, its in-house drafting team develops the panel layouts, incorporating project-specific details such as window and door openings, electrical boxes and wire chases before releasing the models for review.
The panels then move into production and are delivered to the site within the planned three-month timeline. While installation is carried out by the client’s contractor, SIPS of America can recommend experienced installation teams when required.
Quality Control at Every Stage
SIPS of America incorporates multiple quality control checks throughout the manufacturing process. Each morning begins with foam testing, where sample injections are weighed and evaluated to verify that the polyurethane components are balanced before production begins. It also monitors foam performance during expansion and curing to ensure consistency across panel runs.
Once manufactured, panels undergo inspection through FLIR infrared imaging technology for potential voids within the insulated core. This helps verify that the foam has expanded evenly throughout the assembly. From there, the edges are cleaned and placed on 4x4 runners and wrapped in clear plastic, ready for shipment.
These procedures are supported by a team of industry veterans, many of whom bring more than a decade of experience in SIP manufacturing. For projects requiring additional engineering, the company works with external engineering partners such as Tamarack Grove Engineering in Idaho. As per requirements, SIPS of America can also provide wet-sealed engineering calculations for projects throughout the U.S. and neighboring countries.
Looking ahead, it expects continued growth as builders increasingly evaluate alternatives to traditional stick framing. By reducing lumber requirements by 60 percent and limiting thermal bridging, SIP systems offer both construction efficiencies and improved long-term building performance.
By integrating engineering, customization and manufacturing into a single workflow, SIPS of America delivers panel systems that simplify construction, reduce installation effort and improve long-term thermal performance.
Specifying Polyurethane SIP Panels without Losing Control of the Build
Framing decisions now carry more than a material preference. They affect envelope performance, labor planning, inspection readiness and the number of field decisions left to crews under pressure. For executives funding residential developments and custom homes, including timber-frame packages, the risk is rarely the panel concept itself. It is the gap between a promising wall system and the design and shipment discipline needed to make it build cleanly.
Structural insulated panels ask buyers to commit earlier than stick framing. That timing is uncomfortable for teams accustomed to solving conflicts in the field. Door openings, window schedules, electrical paths and roof transitions must be resolved before production rather than after lumber arrives. The payoff can be substantial, but only when the manufacturer treats design coordination as part of the product. Late changes turn factory precision into rework. Loose takeoffs can erase labor savings before the panels reach the trailer.
Lead time is a separate cost line even when it never appears on an invoice. A three-month planning horizon can protect fabrication and delivery, but it also forces architects and owners to settle decisions earlier than many custom projects prefer. Effective manufacturers make that early commitment less brittle through clear models and revision checkpoints.
Thermal performance also needs a more practical reading than nominal R-value. The wall assembly has to reduce thermal bridging while keeping the enclosure tight at seams and penetrations. Polyurethane panels can offer higher insulating value per inch than common polystyrene alternatives, yet the useful question for procurement is how consistently that performance is produced. Foam density and void detection matter because small manufacturing misses become expensive once panels are enclosed in a building.
Speed should be examined with the same restraint. Large panels can shorten the framing phase, especially where repeatable wall sections or timber-frame envelopes are involved. That advantage depends on predictable labeling, edge preparation, shipment packaging and clear installation responsibility. A manufacturer that does not install can still reduce site friction if its drawings, panel sequencing, component prep and handoff notes give local contractors less improvisation. Buyers should be wary of low panel pricing that shifts cutting and box placement back to the field.
Quality control is another purchase issue, not a factory footnote. Polyurethane SIPs involve chemical ratio control and press behavior, both difficult to judge from a quote alone. The manufacturer’s process should include documented checks before injection and inspection after release from the press. Engineering support matters as well, particularly when projects need sealed calculations or location-specific review. The better decision is not simply the thickest panel or the fastest quoted lead time. It is the system that makes design intent and site assembly easier to verify.
SIPS of America is a premier choice for buyers who want polyurethane SIP manufacturing tied closely to project-specific preparation. Its wall and roof panels are built to customer plans, using polyurethane insulated cores and OSB skins, while preconfigured elements such as door bucks, window bucks, electrical boxes, conduit paths and connection components reduce site cutting. The process includes 3D panel renderings, in-house drafting review, fixed contract pricing after approval and infrared foam inspection before shipment. For projects where energy performance must be matched by buildability, it offers a disciplined, practical fit.
