Claims + supporting evidence

A clear claim.
A traceable source.

Know what was modeled, what was observed, and what still needs documentation. A source supports only the conditions it actually addresses.Source review: September 5, 2026 · Not a product certification or project approval.
Engineering model

Thermal performance

R-42–R-50 modeled typical-framing performance equivalent—not a nominal R-value.

Explore this topic →

What the source supports

The two assessed 5.5-inch wood-stud clear-wall configurations model at effective R-20.48–R-21.07. The comparison uses R-19 fiberglass-batt wood and steel baselines, plus assumed, untested leakage and infiltration inputs.

Keep these limits attached

Not a spray-foam comparison, measured utility saving, or universal value for every system. Top and bottom framing are excluded from the clear-wall sections.

Professional field opinion

Mold + indoor air

Three residences: mold-spore sampling in two and separate TVOC/TMVOC sampling in one.

Explore this topic →

What the source supports

Indoor mold counts were below each home's same-day outdoor comparison. The approximately 45,000-sample reference set concerns chemistry, not mold counts or 45,000 unique homes.

Keep these limits attached

One-time observations—not mold-proofing, a health certification, or proof the panels caused the results. The written opinion describes opening, drying, and remediation. The builder later reported drying House3 with drywall in place using a fan and dehumidifier; the accounts differ.

Testing cited by an engineer

Structural testing

ASTM E72-14 testing is cited in the Arrow alternative-material opinion.

Explore this topic →

What the source supports

The opinion identifies CCLI report CCLI-18-121 for axial, transverse, and racking/shear work. The underlying laboratory report is not linked here.

Keep these limits attached

No universal allowable load, wind speed, or project approval is established by the photographs or this summary. Project-specific sealed design is required.

Insulation component evaluation

Fire characteristics

Specified Carpenter EPS products have component surface-burning evaluation data.

Explore this topic →

What the source supports

Applicability depends on the exact product identification, thickness, density, protection, and installation conditions. The evaluation report is not itself the UL Listing/Classification report.

Keep these limits attached

Not an hourly ThermaTech wall-assembly fire rating. In-house demonstrations do not replace accredited laboratory assembly testing.

Company-reported project case

Installation time

One case study reports 14 hours to exterior walls ready for trusses.

Explore this topic →

What the source supports

The report describes 366 linear feet of exterior walls, a three-person crew, and one hour of initial training.

Keep these limits attached

A single reported project—not a typical time, a guarantee, or total construction duration. The separate six-hour claim still needs its own dated job record.

Company-reported project case

Whole-home airtightness

The same case study reports a 2025 blower-door result of 2.65 ACH50.

Explore this topic →

What the source supports

The result describes one occupied home after approximately five years. The original blower-door test sheet is not supplied here.

Keep these limits attached

A whole-building result, not an isolated panel test or a guaranteed outcome.

Not yet substantiated

These items need their paperwork.

They are not part of the documented performance claim set above. A disclaimer is not a substitute for evidence.

Wind-speed figures

The original dated planning calculation is needed before publishing a numerical wind claim. Site conditions, loads, connections, and engineering govern each building.

Six-hour setup claim

A dated project log must identify wall scope, crew size, site preparation, and the start and finish used for timing.

109 years combined experience

Dated team biographies and a documented calculation are needed to substantiate this total.

In-house fire demonstrations

Test A and Test B require the footage and dated records of the assembly, procedure, temperature measurement, duration, and observations. No fire-resistance rating is claimed.

Truss ties + exact steel profiles

The supplied truss drawing shows a connection concept but does not identify a complete connector and fastener specification. Confirm the approved detail before treating the animation as installation guidance.

Wood species, treatments + material performance

A rendering does not identify a supplied product. Claims about treated lumber, decay, insects, or fire performance require the exact product documents and applicable test or listing.
