What is the best continuous insulation system?
The best continuous insulation system is the one that performs across all eight best practices an architect has to defend on a commercial project: thermal efficiency, structural integrity, fastener retention, durability, fire resistance, building health, environmental impact, and ease of installation. A system that wins on thermal efficiency but fails the ASCE fastener-retention standard is not a defensible specification. The right method is to score each system across all eight best practices, then choose the system that clears every threshold for your project’s program, code path, and energy targets.
If you are evaluating continuous insulation right now, you are really choosing among five approaches: an integrated composite metal hybrid building enclosure system (SMARTci®), a composite metal hybrid continuous insulation framing system (GreenGirt CMH™), a generic 16-gauge steel Z-girt, a perforated thermal metal Z-girt, or an FRP-only Z-girt. Two of those five meet the criteria across all eight best practices, and both are part of Advanced Architectural Products’ portfolio of building enclosure systems: SMARTci® building enclosure systems and the GreenGirt CMH™ continuous insulation system. Think of this as a continuous insulation specifier’s guide: it gives you the framework to compare the best continuous insulation systems for commercial construction yourself, so the choice is yours to defend, not ours to assert.
Is there one best continuous insulation system?
Yes, when you evaluate across all eight best practices. SMARTci® and GreenGirt CMH™ are the only two systems in the market that clear every threshold: up to 99 percent whole-system thermal efficiency, permanent steel-to-steel fastener retention, project-specific engineering, and NFPA 285 compliance. Every other system wins on one or two practices but carries a documented weakness: generic steel loses on thermal efficiency; perforated thermal metal gives back thermal gains to creep; FRP-only fails the ASCE fastener-retention standard.
The difficulty is that every manufacturer can point to a best practice where their system leads. A perforated metal Z-girt brochure promotes with thermal numbers, an FRP Z-girt brochure with a static R-value, a steel Z-girt on first cost. None of that answers whether the system holds up across fire resistance, fastener retention, durability, and environmental impact all at once.
A real comparison scores each system across all eight best practices. That turns a continuous insulation comparison into something you can defend with an owner or code official. The matrix below lets you verify this yourself.
What are the criteria for selecting a continuous insulation system?
Score every continuous insulation system against eight best practices: (1) thermal efficiency, (2) structural integrity, (3) fastener retention, (4) durability, (5) fire resistance, (6) building health, (7) environmental impact, and (8) ease of installation. These are the same eight best practices A2P’s engineering best-practices library is organized around, and they map one-to-one to the questions a commercial project forces you to answer.
Use this list as your continuous insulation system evaluation criteria, or continuous insulation system selection criteria, whichever your spec calls it. For each best practice, there is one question to ask the manufacturer and one place to dig deeper.
- Thermal efficiency. Whole-system, lifetime R-value retention, not the label value of the board. Thermal bridging and thermal bypass at every transition. Ask: What is the as-built effective R-value across the full assembly, including every penetration, transition, and fastener? Dig deeper: thermal efficiency best practices, the thermal bypass deep-dive, and thermal window framing for the window-opening case.
- Structural integrity. Load capacity for the cladding and the wind and seismic environment. Deflection and cantilever behavior under sustained and live loads. Ask: Does the manufacturer perform project-specific finite element analysis? Dig deeper: structural integrity best practices.
- Fastener retention. Permanent steel-to-steel connections that meet the ASCE durability standard. Ask: Does the cladding fastener land in a Z-girt that meets ASCE durability criteria, or one ASCE flags for connection failure? Dig deeper: fastener retention best practices.
- Durability. Creep behavior under sustained load. Material stability at temperature extremes. Z-girt service life measured against the building’s service life. Ask: What is the documented service life, and is it backed by third-party engineering reports? Dig deeper: durability best practices.
- Fire resistance. NFPA 285 wall-configuration coverage. ASTM E84 surface burning characteristics. Ask: Is the specific cladding-and-insulation assembly you are specifying confirmed against an NFPA 285 tested assembly or a documented Engineering Judgment? Dig deeper: fire resistance best practices.
- Building health. Air- and water-tightness. Condensation control and vapor management at transitions. Indoor environmental quality. Ask: Is the assembly air- and water-tight in the as-built condition? Dig deeper: building health best practices and the thermal bypass deep-dive for the air-leakage detail.
- Environmental impact. Published EPDs. Declare Label compliance. Living Building Challenge Red List Free status. Halogen- and bromine-free composition. LEED v5 credit support. Ask: Are the EPD, Declare Label, and Red-List-free documents public, or do you have to request them? Dig deeper: environmental impact best practices.
- Ease of installation. Progressive, stack-and-go assembly. Integrated insulation retention. Field-constructable details. Ask: Can the system be installed without supplemental fasteners or coordination breaks between trades? Dig deeper: ease of installation best practices.
All eight apply on every commercial wall. That is the purpose of A2P’s engineering best practices hub: none of these best practices is optional.
How do SMARTci®, GreenGirt CMH™, steel, perforated thermal metal, and FRP-only Z-girts compare?
Across the eight best practices, SMARTci® and GreenGirt CMH™ clear every threshold: up to 99 percent whole-system thermal efficiency, permanent steel-to-steel fastener retention, project-specific engineering, NFPA 285 and ASTM E84 fire compliance, and published environmental documentation. Generic steel Z-girts hold fastener retention but lose thermal efficiency to conductivity. Perforated thermal metal Z-girts land around 70 to 80 percent thermal efficiency and are susceptible to creep. FRP-only Z-girts post a high static R-value but carry the ASCE fastener-durability concern and limited fire-test coverage.
The condensed matrix below summarizes each best practice across all five systems. Every cell traces to a verified A2P source, a published test standard, or a third-party report. The full comparison chart with footnoted citations lives on the full continuous insulation systems comparison page.
| Best Practice | SMARTci® | GreenGirt CMH™ | Steel Z-Girt (16-gauge) | Perforated Thermal Metal Z-Girt | FRP-only Z-Girt |
|---|---|---|---|---|---|
| 1. Thermal efficiency | Highest in market; up to 99% whole-system | High; up to 99% whole-system | Lowest; highly conductive | ~70–80% | High static R, degrades under creep |
| 2. Structural integrity | Project-specific FEA on every project (on request) | Same | Catalog product | Catalog product | Catalog product |
| 3. Fastener retention | Steel-reinforced flanges; permanent steel-to-steel | Same | Solid steel; permanent | Permanent where steel intact | Temporary; screws creep |
| 4. Durability (creep) | ASTM D2990; eliminates creep | Same | Steel resists creep | Susceptible at polymer break | Susceptible to creep |

| 6. Building health | Only system air- & water-tight without caulk or tape, with foil-faced polyiso | No self-seal at framing | No self-seal | No self-seal | No self-seal |
| 7. Environmental impact | CMH framing is Declare/Red List Free/EPD, halogen- & bromine-free; insulation varies | Same | Generic steel is Red List Free | Polymer break often not Red List Free | Often not halogen-/Red List Free |
| 8. Ease of installation | Stack-and-go; ThermaLock™ holds insulation without stick pins in most configurations | Stack-and-go; ThermaLock™ (most configurations) | No progressive system | No integrated retention | No progressive system |
The SMARTci® whole-wall performance is documented in the third-party DrJ Technical Evaluation Report (TER 1501-06).
How much thermal performance does each system actually keep?
Independent 3D thermal modeling by Morrison Hershfield/Stantec, run to ASHRAE and CSA standards and accounting for every fastener, puts GreenGirt CMH™ and SMARTci® at up to 99 percent whole-system thermal efficiency over the building’s service life; both eliminate the through-insulation metal and through-fasteners that cause thermal bridging. Perforated thermal metal Z-girts typically land in the 70 to 80 percent range, and generic steel Z-girts perform lowest because steel is highly conductive.
Thermal efficiency is the best practice most architects lead with, and it is the one most often overstated. The R-value printed on an insulation board is a starting point, not the number the building gets. What the wall keeps depends on how much metal and how many fasteners pass straight through the insulation, and on whether air can move behind it. For the air-movement half of that story, see the thermal bypass deep-dive; for the window-opening half, where wall continuous insulation usually breaks down, see thermal window framing and the Psi value work behind it.
Who proves the system carries the load?
A2P performs project-specific finite element analysis and engineering review on every SMARTci® and GreenGirt CMH™ project, and provides that documentation to the architect and structural engineer on request. Generic steel, perforated thermal metal, and FRP-only Z-girts are sold as catalog products, which leaves the project’s architect and structural engineer to validate load capacity, deflection, and cantilever behavior independently.
This is a quiet but expensive difference. A catalog Z-girt gives you a published allowable load and a span table. A system that includes engineering gives you a calculation against your cladding weight, your wind and seismic loads, and your substrate. On a project with seven cladding types or an aggressive cantilever, that distinction decides whether the envelope is engineered or assumed. The full treatment is in structural integrity best practices.
Will the connection still be there in thirty years?
The ASCE Design Guide for FRP Composite Connections (page 19) does not recommend self-tapping sheet-metal screws for fastening into pultruded FRP, pointing to bolted, adhesively bonded, or combined connections instead. SMARTci®, GreenGirt CMH™, and steel Z-girts all connect steel-to-steel through steel-reinforced flanges or a solid steel flange, so the ASCE concern does not apply. Fasteners into FRP-only Z-girts are characterized as eventually leading to “unavoidable failure.”
Fastener retention is about keeping cladding anchored for the life of the wall. GreenGirt CMH™ and SMARTci® use steel-reinforced flanges for permanent steel-to-steel fastening. FRP-only Z-girts can only be used in a temporary capacity: screw connections in pultruded FRP lose retention through creep under sustained load, and the ASCE Design Guide for FRP Composite Connections does not recommend self-tapping screws for FRP, pointing to bolted, adhesively bonded, or combined connections instead. For the engineering behind it, see fastener retention best practices, the comparison of FEA and Poisson’s ratio in FRP versus composite metal hybrid, and fiber-reinforced polymer versus steel in modern construction.
Does the system outlast the building, or wear out inside it?
SMARTci®, GreenGirt CMH™, and generic steel Z-girts eliminate material and fastener creep; the A2P systems are tested to ASTM D2990 to confirm it. Perforated thermal metal Z-girts are mostly steel, but some polymer thermal breaks within their product design are susceptible to creep and force concentrations under sustained load. FRP-only Z-girts are susceptible to creep under sustained loading.
Durability and fastener retention are related. Creep is the slow deformation of a material under constant load, and it is the mechanism behind both a loosening fastener and a sagging Z-girt. The question to put to any manufacturer is simple: is the service life documented in a third-party engineering report? See durability best practices for the test basis.
How much of your wall is actually fire-tested?
SMARTci® and GreenGirt CMH™ are compliant with NFPA 285 and ASTM E84 across the commercial wall configurations A2P supports. Rather than a fixed count of wall types, the qualification rests on a single worst-case tested assembly, ACM panels without exterior sheathing, extended by an Engineering Judgment from Priest & Associates Consulting and validated by DrJ Technical Evaluation Report 1501-06. That judgment approves use with NFPA 285-approved products from Atlas, Rmax, Hunter, Carlisle, and Dow, mineral wool, and high-pressure laminate claddings in an approved window-header design. FRP-only Z-girts have been tested only in limited cladding-and-insulation combinations.
The number of cladding-and-insulation combinations is effectively open-ended, and small differences matter: an insulation depth that does not match the girt depth, or a switch to a more vapor-open insulation like XPS (which narrows the compliant cladding options), can change the result. What matters is that the specific assembly you are specifying is confirmed against a tested assembly or a documented Engineering Judgment, not that a system claims a fixed number. For the standards themselves, see fire resistance best practices, the NFPA 285 overview, NFPA 285 and ASTM E84 testing with GreenGirt CMH and SMARTci, and the NFPA 285 wall details.
Is the wall actually air- and water-tight, or only on paper?
SMARTci® is the only system in this comparison that achieves an air- and water-tight assembly. Installed over traditional closed framing with sheathing and a water-resistive barrier, it is water-tight to 1.57 PSF and air-tight to 6 PSF. Adding caulk and tape lets SMARTci® replace the sheathing and water-resistive barrier and raises air- and water-tightness to 20 PSF.
Building health is where the difference between modeled and as-built performance shows up. When specified with foil-faced polyiso, SMARTci’s ThermaLock™ technology forms dual three-point compression seals that make the assembly air- and water-tight without caulk or tape. This best practice is tightly coupled to thermal efficiency through air movement, so the thermal bypass deep-dive is the companion read, along with building health best practices and how GreenGirt CMH and SMARTci transform rainscreen performance.
Can you document the green claims, or only repeat them?
The GreenGirt CMH™ Z-girt component, used in both the SMARTci® and GreenGirt CMH™ systems, is halogen- and bromine-free, uses naturally-sourced fire retardants, and meets Declare Label, Living Building Challenge Red List Free, and EPD requirements. These attributes apply to the Z-girt component specifically; rigid insulation chosen for a SMARTci® assembly varies and may not meet all of them. Generic steel and perforated thermal metal Z-girts are also Red List Free; FRP-only Z-girts often are not.
For a LEED v5, Passive House, or PHIUS project, the proof has to be public and project-ready, not promised. Ask for the EPD, the Declare Label, and the Red-List documentation up front. See environmental impact best practices and using GreenGirt CMH and SMARTci to hit aggressive energy thresholds under LEED v5.
Will the system install the way it is drawn?
GreenGirt CMH™ Z-girts interlock without cantilevering, and the girts use ThermaLock™ technology that helps retain insulation in most configurations. When A2P supplies rigid insulation, integrated retention splines hold it in place, providing a stack-and-go installation process. Generic steel and some perforated thermal metal Z-girts require supplemental retention fasteners by default.
Ease of installation carries real schedule and cost consequences. Supplemental stick pins, scaffolding redesigns, and trade coordination breaks all add field hours that never appeared in the spec. A progressive, stack-and-go system keeps the install close to the drawing. See ease of installation best practices and combining multiple A2P systems on one envelope.
The systems in this comparison are built on GreenGirt CMH™, which consists of a composite metal hybrid material that combines thermal break performance with steel-grade structural capacity in one element. That single material is why the A2P columns clear thermal efficiency and fastener retention at the same time, rather than trading one for the other.
How do I specify continuous insulation for my project?
Score every system across all eight best practices, eliminate any system with a hard “no” in a category your project cannot compromise on, then weigh your top two or three best practices by project type. A LEED Platinum K-12 project may weigh environmental impact, building health, and thermal efficiency. A high-rise hospitality project may weigh fire resistance and structural integrity. Choose the system that clears your non-negotiables and is backed by project-specific engineering support.
Here is how to specify continuous insulation in five steps:
- List your project’s non-negotiables across all 8 best practices. Code path (ASHRAE 90.1, IECC, IBC), climate zone, NFPA 285 requirement, sustainability targets (LEED, Passive House, PHIUS), structural and seismic loads, and schedule pressure.
- Score every candidate system on every best practice. Not just thermal. A system that wins on thermal efficiency but fails ASCE fastener retention is not a defensible specification.
- Eliminate any system with a hard “no” in a best practice you cannot give up. A “limited” in NFPA 285 coverage or a flagged fastener substrate ends the evaluation for that system on that project.
- Weigh your top two or three best practices. The same comparison produces different answers on different buildings, and that is correct.
- Choose the system backed by engineering support. A2P performs project-specific FEA on every SMARTci® and GreenGirt CMH™ project and provides the documentation on request, plus field support. Catalog products leave that validation to the architect and structural engineer. GreenGirt Steel™ is A2P’s entry-level steel-based option and offers the highest thermal efficiency available in a steel-based system.
To apply the scorecard to your project, compare SMARTci® and GreenGirt CMH™ side by side or talk to A2P engineering about your project.
Where do the eight best practices hold up on real buildings?
The framework is not academic. On three very different projects, three different best practices led the decision, and the same comparison method produced three appropriate system selections. Evaluating against all eight best practices is what lets the right answer adapt to the specific project.
Madison, WI • College & University
University of Wisconsin School of Computer, Data & Information Sciences (Morgridge Hall)
Why it matters: a seven-story building targeting LEED Platinum, the most sustainable on its campus, lives on whole-system thermal efficiency and documented environmental performance. Pairing wall continuous insulation with window thermal framing keeps the wall’s performance from being given back at the openings.

Why it matters: a hospitality facade has to carry its cladding securely while keeping the insulation continuous behind it. GreenGirt CMH supports the Dri-Design cladding on 2-inch vertical girts at 16-inch on-center without breaking the insulation layer, which is the structural-integrity question this project turned on.

Why it matters: a large all-suite hotel pairs heavy stone with fiber cement, so the enclosure has to carry a substantial dead load while managing air and moisture as one system. SMARTci supports the stone on girts that keep an unbroken insulation layer, and installing it as an integrated enclosure keeps the exterior on schedule.

How do the eight best practices map to code and energy targets?
ASHRAE 90.1 made continuous insulation a requirement, not an option, across most climate zones, and energy models increasingly reflect thermal bridging through effective R-value rather than crediting the full nominal R-value of the board. The eight best practices map directly to a code-compliant, energy-model-honest specification: thermal efficiency and building health carry the energy case, fire resistance carries the IBC and NFPA 285 case, and environmental impact carries the LEED v5 and Passive House case.
A few specifics worth holding onto. ASHRAE 90.1 continuous insulation requirements set the floor by climate zone; the question is whether your assembly keeps the R-value the model assumed. The best continuous insulation system for ASHRAE 90.1 compliance is therefore the one that loses the least to thermal bridging and air movement between the board and the as-built wall. An effective R-value that accounts for thermal bridging is lower than the board’s nominal R-value, which is why thermal efficiency and building health are linked best practices rather than separate ones. On commercial walls, NFPA 285 coverage is non-negotiable, and the comparison matrix above reflects per-system coverage rather than a blanket claim. For LEED v5 and Passive House or PHIUS work, an integrated wall-and-window continuous insulation assembly supports the energy and atmosphere credits, documented in using GreenGirt CMH and SMARTci under LEED v5.
Frequently Asked Questions
What is the best continuous insulation system?
The best continuous insulation system for a given project is the one that clears every threshold across eight best practices: thermal efficiency, structural integrity, fastener retention, durability, fire resistance, building health, environmental impact, and ease of installation. Among the five most-specified approaches, SMARTci® and GreenGirt CMH™ are the two that meet the criteria across all eight. Compare them side by side.
How do I evaluate a continuous insulation system?
Score each system across the eight best practices above, eliminate any system with a hard “no” in a best practice your project cannot compromise on, then weigh your top two or three best practices by project type. The full method is in the engineering best practices hub.
What are the 8 best practices every architect should evaluate when choosing a continuous insulation system?
Thermal efficiency, structural integrity, fastener retention, durability, fire resistance, building health, environmental impact, and ease of installation. Each maps to a dedicated engineering best-practices page so you can go as deep as the project requires.
What is the difference between SMARTci® and GreenGirt CMH™?
GreenGirt CMH™ is the continuous insulation framing system, with up to 99 percent whole-system thermal efficiency and permanent steel-to-steel fastener retention. SMARTci® is the integrated building enclosure system that includes GreenGirt CMH Z-girts with custom-profiled rigid insulation panels to eliminate thermal bypass and achieve an air- and water-tight wall. See the GreenGirt CMH continuous insulation system. See the SMARTci building enclosure system.
Which is better for my project: SMARTci, GreenGirt CMH, steel, perforated thermal metal, or FRP Z-girts?
SMARTci® and GreenGirt™ are the best options. You don’t have to make any compromises when choosing an A2P system.
What is the best continuous insulation system for ASHRAE 90.1 compliance?
ASHRAE 90.1 sets a continuous insulation requirement by climate zone, so the best continuous insulation system for 90.1 is the one that keeps the assembly’s effective R-value closest to the modeled value. Systems that eliminate through-insulation metal and through-fasteners, like SMARTci® and GreenGirt CMH™, retain the most. Read the thermal efficiency best practices.
What is the best continuous insulation system for NFPA 285 commercial wall fire testing?
SMARTci® and GreenGirt CMH™ are compliant across supported commercial configurations through a tested worst-case assembly plus an Engineering Judgment covering Atlas, Rmax, Hunter, Carlisle, Dow, and mineral wool insulation; FRP-only Z-girts are tested only in limited combinations. See the NFPA 285 overview.
What is the best continuous insulation system for LEED v5 or Passive House projects?
For green-building projects, prioritize environmental impact and building health alongside thermal efficiency. The GreenGirt CMH™ framing component is Declare Label compliant, Red List Free, and EPD-documented, and an integrated wall-and-window assembly supports aggressive energy targets. See the LEED v5 application.
Are FRP-only Z-girts a good continuous insulation system?
FRP-only Z-girts are a temporary solution and they carry two documented concerns: the ASCE Design Guide for FRP Composite Connections does not recommend self-tapping screws into pultruded FRP, and FRP is susceptible to creep under sustained load. They are also tested in limited fire configurations. See FRP versus steel in modern construction. For permanent solutions, choose a system that has the thermal efficiency benefits of FRP, but paired with the structural strength of steel, such as composite metal hybrid based systems, SMARTci and GreenGirt CMH.
Are perforated thermal metal Z-girts a good continuous insulation system?
Perforated thermal metal Z-girts improve on generic steel but typically land around 70 to 80 percent whole-system thermal efficiency, because the steel Z-profile is still the primary load path, and they may be susceptible to creep at the polymer break. Some also require supplemental insulation-retention fasteners. Compare the systems in detail.
How does GreenGirt Steel™ fit into this comparison?
GreenGirt Steel™ is A2P’s entry-level steel-based continuous insulation system, and it offers the highest thermal efficiency available in a steel-based system, reaching into the 90 percent range. Like GreenGirt CMH™, it includes built-in insulation retention that holds rigid or mineral wool insulation without stick pins, and uses steel-to-steel connections that meet the ASCE durability standard, with project-specific finite element analysis on every order. It does not provide SMARTci’s air- and water-tight, thermal-bypass-eliminating assembly, so it is the right choice when a project’s performance targets are standard rather than aggressive. Specify the GreenGirt Steel continuous insulation system.
How is thermal bypass different from thermal bridging?
Thermal bridging is heat conducted through a solid material, like a steel Z-girt, that creates a low-resistance path through the insulation. Thermal bypass is air moving through gaps and voids behind the insulation, including wind washing and stack effect. A system can fix one without the other. Read the thermal bypass deep-dive.
Does the window opening matter when evaluating a wall continuous insulation system?
Yes. Wall continuous insulation is routinely given back at every window, where the framing creates a thermal bridge that undermines the wall you just specified. Evaluating a wall continuous insulation system without the opening detail overstates real performance. See thermal window framing.
Do GreenGirt CMH and SMARTci need hat channels or a separate sub-girt layer for cladding?
In most assemblies, no. GreenGirt CMH™ and SMARTci® are engineered for direct cladding attachment: the cladding fastens to the girt’s steel-reinforced flanges, so one system carries the cladding and holds the continuous insulation without an added sub-girt or hat-channel layer. That keeps the insulation continuous and removes a trade and a material from the wall. Hat channels and sub-girt-on-Z-girt assemblies, by contrast, are attachment add-ons that still require a continuous insulation board behind them. See cladding attachment methods with continuous insulation and enclosure systems.
How much does the best continuous insulation system cost?
A2P does not publish per-square-foot material or installed pricing, because total cost depends on how the system is specified. Three variables drive installed cost: (1) girt spacing: wider spacing reduces girt linear feet and labor cost; (2) installation speed: a stack-and-go system with integrated retention eliminates supplemental fasteners and trade coordination, lowering crew hours; and (3) cladding attachment: direct-to-girt fastening eliminates a sub-girt layer, while hat-channel assemblies add material and labor. On a lifecycle basis, permanent steel-to-steel connections avoid callbacks and creep-driven replacement, and higher thermal efficiency lowers 20-year operating cost. Ask your contractor to compare installed cost across girt spacing scenarios, and talk to A2P engineering for a project-specific total-cost picture.
