SIP Manufacturers
A complete, engineer-authored guide for builders, designers, and project teams, written by Joe Pasma, PE, with more than 40 years of SIP engineering, manufacturing, and field experience. Published July 2026, Updated September 9, 2026
About This List
This is an independent reference list of active SIP manufacturers worldwide, covering the United States, Canada, Mexico, the United Kingdom, Europe, Australia, New Zealand, and China. This list includes only companies that physically manufacture Structural Insulated Panels. Resellers, installers, and kit-only providers are excluded.
Key Takeaways
This list covers active SIP manufacturers in North America, the UK, Europe, Australia, New Zealand, and China
Most manufacturers specialize in one or two core types: EPS, GPS, or PUR/PIR
SIPA, Structural Insulated Panel Association, membership is voluntary and does not determine quality or code compliance
For North American projects, a current ICC-ES, PFS TECO, IAMPO UES, DrJ Engineering (DJEI), or CCMC code report is the most reliable indicator of third-party verification
Code compliance requirements vary significantly by country — always verify applicable standards directly with the manufacturer for your project location
The right manufacturer depends on core type, facing materials, code jurisdiction, and project-specific requirements

Why This List Exists
When builders, architects, or project teams reach out to PGS Consulting LLC, one of the first questions is usually simple: who actually makes Structural Insulated Panels in North America?
The SIP industry is more fragmented than most people expect. Dozens of companies market "SIP packages" or "SIP systems," but many do not manufacture panels themselves. They source from a third-party manufacturer and resell or repackage. That distinction matters when you are evaluating performance, code compliance, and system consistency.
This list was built through a combination of:
SIPA member directory review
ICC-ES and CCMC code report verification
Manufacturer website validation
Historical industry records
Independent research and direct confirmation
The goal is a clean, manufacturer-only reference. No resellers. No installers. No kit-only providers.

SIP Core Types: What the Differences Actually Mean
Not all SIPs are built the same. The insulation core is what separates one manufacturer's product from another, and it affects thermal performance, structural behavior, long-term durability, and cost.
EPS: Expanded Polystyrene
EPS is the most widely used core material in the SIP industry. It is cost-effective, dimensionally stable, and its R-value holds steady over the life of the building. R-values typically run from R-3.6 to R-4.5 per inch. Most builders working with SIPs for the first time will use EPS.
GPS: Graphite Polystyrene
GPS is EPS with graphite particles added. The graphite reflects radiant heat and pushes R-values up to R-4.7 to R-5.1 per inch. It installs exactly like EPS, making it a straightforward upgrade for projects targeting higher performance or net-zero certification.
PUR / PIR: Polyurethane-Based Systems
PUR and PIR cores start at R-6.0 to R-7.2 per inch. These systems experience thermal drift over time: long-term aged R-values settle between R-5.0 and R-6.5. EPS and GPS do not drift. PUR/PIR is most common in commercial applications, cold storage, and projects requiring thinner panels with maximum initial performance.
Engineer's Note
The choice of core type should always be made in the context of the full building system. Performance goals, climate zone, code requirements, and long-term cost all affect which core makes sense for a given project.
Facing Materials
OSB-Faced SIPs
Most SIPs use OSB facings on both sides. OSB is strong, well-understood, and compatible with standard framing connections.
MgO-Faced SIPs
A growing category that uses magnesium oxide board in place of traditional OSB facings. MgO boards offer different fire resistance and moisture characteristics, typically selected for applications where non-combustibility of the facing is required or enhanced durability is a priority.
How to Choose the Right SIP Manufacturer
Choosing a SIP manufacturer is a system decision, not a product decision. The differences between manufacturers are not always visible in a spec sheet or a website. They show up in engineering support, manufacturing consistency, and what happens when something does not go as planned.
Start with core type and performance requirements
Your climate zone, energy targets, and budget will narrow the field quickly. Most manufacturers produce EPS panels. Fewer produce GPS. PUR/PIR and MgO-faced systems come from a smaller subset. Once you know which core type fits your project, the list of viable manufacturers gets much shorter.
Check code compliance
Look for a current evaluation report (U.S.) or CCMC report (Canada). These are third-party documents that verify a manufacturer's panels have been tested and evaluated against code specific performance criteria. A valid code report tells you the system has been independently reviewed. Its absence means the burden of demonstrating compliance falls elsewhere.
Ask about manufacturing quality
Panel performance starts on the factory floor. Bond quality, adhesive consistency, dimensional accuracy, and quality control procedures all affect how panels perform in the field and how they hold up over decades. These are not things you can assess from a website. Asking the right questions, or working with someone who has been inside the plants, makes a meaningful difference.
Evaluate engineering and installation support
The best SIP systems come with engineering support that connects panel design to the structural loads and spans of your specific project. Manufacturers that provide clear sequencing guidance, connection details, and field support reduce errors and expensive field changes.
Match the manufacturer to your project
There is no universally "best" SIP manufacturer. The right choice is the one that fits your project's structural requirements, climate zone, installation team, code jurisdiction, and schedule. A manufacturer that is ideal for a cold-climate residential project in Minnesota may not be the right fit for a commercial build in Florida.
For a deeper look at each of these factors -- including the questions worth asking any manufacturer and the red flags Joe has seen in 40 years of plant visits -- read the full guide: How to Choose the Right SIP Manufacturer.

Talk to Joe About Your Project →Frequently Asked Questions About SIP Manufacturers
How many SIP manufacturers are there in North America?
There are roughly 40 to 45 active SIP manufacturers across the United States, Canada, and Mexico. This list includes only companies that physically manufacture SIPs, not resellers or installers.
Why are some companies not on this list?
Many companies in the SIP space are installers, kit providers, or resellers, not manufacturers. They may market SIP packages, but the panels themselves are produced by a third-party manufacturer. This list is limited to companies that actively produce SIPs.
Does SIPA membership mean a manufacturer is more reliable?
Not necessarily. SIPA membership is voluntary. Several long-standing, well-regarded manufacturers are not SIPA members. A current evaluation report or CCMC report is a more reliable indicator of third-party verification than membership status alone.
What is an ICC-ES code report and why does it matter?
An ICC-ES evaluation report is a third-party document authored by ICC-ES confirming that a manufacturer's panels have been tested and evaluated against specific code requirements. If a manufacturer has a current ICC-ES report, you have documented evidence the system has been independently reviewed. If they do not, compliance verification requires more work on the builder or engineer side.
What is the difference between EPS, GPS, and PUR/PIR SIPs?
EPS is the most common core: cost-effective, stable R-value, widely code-recognized. GPS adds graphite to boost R-value per inch without changing the installation process. PUR/PIR offers the highest initial R-value but experiences thermal drift over time, meaning long-term performance is lower than the initial rating. EPS and GPS do not drift.
How do I evaluate a SIP manufacturer I have not worked with before?
Start with three questions: Do they have a current code report? What is their quality control process? What engineering support do they provide for your project type? Working with an independent SIP consultant who has direct manufacturing experience can accelerate this evaluation considerably.
