Evidence stories

Plain-language first. Full context when you want it.

Each topic keeps the result, the kind of evidence, and the limitation together—so a useful number is never mistaken for a universal rating.

01 / Moisture + mold

Three residences. Two kinds of sampling.

3 residences

Mold-spore sampling in two; separate TVOC/TMVOC sampling in one.

The two mold-sampled homes showed indoor counts below their same-day outdoor comparisons. The third residence had low chemistry measurements relative to the report’s cited reference data.

One-time field observations—not a mold-proof claim, certification, causal finding, or guarantee.

Two useful numbers answer two different questions.

R-20.48–R-21.07

Modeled effective clear-wall range for the two assessed 5.5-inch configurations.

R-42–R-50 is the modeled typical-framing performance equivalent in Intertek’s total-heat-loss comparison. It is not a nominal or laboratory-tested wall R-value.

The comparison includes assumed, untested air-leakage and infiltration inputs. Whole buildings vary.

See the panel under load. Keep engineering attached.

ASTM E72

Testing cited by the related Arrow alternative-material opinion.

Photographs document a ThermaTech specimen in a loading rig. Exact allowable values, geometry, load paths, connections, and local acceptance still require the source report and project-specific sealed design.

Test imagery documents the setup; it does not publish an allowable load or establish project approval.

Project-dependent questions

Wind and fire need the complete assembly.

These topics cannot be reduced to one universal product number. Start with the available component or planning information, then confirm the exact project.
04 / Wind design

Wind is a load path—not a sticker with one speed.

Project-specific design

Review wind loads, panels, connections, and anchorage as a complete load path. A numerical rating needs its underlying calculation and project conditions.

Height, exposure, geometry, openings, connections, anchors, and local criteria change the answer.See the documentation needed Request a project wind review
05 / Fire strategy

Document the material. Protect the assembly.

Component evidence

Review the Carpenter EPS evaluation report for component surface-burning characteristics and installation conditions. It does not establish an hourly ThermaTech wall-assembly fire rating.

Confirm the actual insulation product and required protection. This evaluation report is not itself the UL Listing/Classification report.Open Carpenter EPS evaluation Source scope + limitations

In-house demonstrations

See what happened. Keep the test conditions visible.

These spaces are for the two company demonstrations. Videos and dated test records are not available yet; no duration, temperature, or fire-resistance rating is verified here.
Test A · video pending

⅝-inch Type X drywall

Planned record: assembly materials, heat exposure, measurement method, duration, and post-test condition.

Test B · video pending

½-inch drywall

Planned record: when the lining failed, what entered the cavity, and the observed condition after the test.

In-house demonstrations are not accredited laboratory fire-resistance tests and cannot establish an hourly assembly rating.

Instructions at the task.

Focused field pages cover setting, bottom plates, panel modifications, openings, electrical routing, and blocking.

Not a guaranteed schedule or total construction time. Project size, complexity, weather, access, slab tolerances, engineering, logistics, and crew readiness can change the timing.Open the instruction library
