FAQ — Argentmantle

Question 1

What does Argentmantle cost, and how does it compare to other fire-hardening measures?

Accepted Answer

Argentmantle is priced as a per-unit line item in the builder's material spec — comparable to a premium window package or a whole-home generator. Exact pricing depends on roofline configuration and unit count; contact us for a project-specific quote. The relevant comparison is not to other fire-hardening products but to the cost of uninsurability: in California's WUI market, homes without documented ignition-resistant assemblies are increasingly difficult to insure through admitted carriers. The system pays for itself in the first renewal cycle for most buyers in high-risk zones.

Question 2

Is the 3,500°F rating credible? What does it actually mean in a wildfire?

Accepted Answer

The 3,500°F rating refers to direct flame impingement on the deployed blanket surface — the temperature of a fully involved wildfire front at close range. This is not a marketing claim; it is a third-party laboratory test result conducted under ASTM E119 and UL 263 protocols. In practice, most WUI homes are not destroyed by direct flame contact — they are destroyed by ember intrusion and radiant heat. The Argentmantle system addresses all three heat transfer modes: the aluminized ceramic face reflects up to 97% of radiant energy, the aerogel core blocks conductive heat transfer, and the deployed blanket eliminates the eave gaps through which embers enter. Third-party test reports are available on request.

Question 3

Does Argentmantle satisfy California Chapter 7A requirements?

Accepted Answer

Yes. Argentmantle meets and exceeds CBC Chapter 7A requirements for eave and soffit assemblies in WUI-designated zones. We provide a section-by-section compliance matrix formatted for permit submission and plan check. The system has been reviewed by licensed fire protection engineers and is designed for straightforward plan check approval in California jurisdictions. Chapter 7A compliance documentation is included in the standard builder documentation package.

Question 4

Will installing Argentmantle actually affect my insurance premium or availability?

Accepted Answer

This is the right question, and the honest answer is: it depends on the carrier. Admitted carriers have largely exited the California WUI market, and the surplus lines market is still developing its underwriting criteria for ignition-resistant construction. What Argentmantle provides is the documentation infrastructure that makes the conversation possible: third-party test reports, a compliance matrix, and a per-unit certificate of installation. Several surplus lines underwriters have indicated that homes with documented ignition-resistant eave systems qualify for favorable treatment. We do not make specific premium reduction claims — we provide the documentation that lets your broker make the case.

Question 5

Can Argentmantle be retrofitted to an existing home, or is it new construction only?

Accepted Answer

The current system is designed for new construction — it integrates into the eave assembly during rough framing, before roofing and exterior cladding. A retrofit variant is in development for existing homes with accessible eave assemblies, targeted for availability in 2027. If you are rebuilding after a fire event, the new construction system applies: a rebuild is a new construction project for permitting and installation purposes. Contact us to discuss your specific project.

Question 6

How long does installation take, and does it require a specialized contractor?

Accepted Answer

Installation adds approximately four hours to a standard framing crew's schedule for a 2,400 sq ft roofline. No specialized fire-mitigation contractor is required. The system is designed for installation by the framing subcontractor using standard tools. We provide a one-page installation guide, a 30-minute video walkthrough, and a pre-installation checklist. For builders adding Argentmantle to a production schedule, we offer a half-day on-site training for the framing crew on the first project — at no additional cost.

Question 7

What is the warranty, and what happens to the system after a fire event?

Accepted Answer

Argentmantle carries a 10-year warranty on the blanket assembly and thermal trigger mechanism under normal conditions. After a fire event in which the blanket deployed, panels that sustained direct flame contact are replaced individually — the system does not require full reinstallation. Replacement panels ship within 72 hours of a service request. The thermal trigger mechanism is inspected and recertified as part of the post-fire service protocol. A post-fire service visit is included in the warranty for the first deployment event.
