The technology
How the shield works.
A ceramic-aerogel blanket lives in the eaves. When fire threatens, it deploys in under four minutes and wraps the structure in a 3,500°F-rated reflective cocoon.
Integrated at construction
The Argentmantle blanket is factory-installed into the eave assembly during framing — flush with the roofline, invisible from the street. No retrofit required. No external hardware. The system is part of the building envelope from day one.
Thermal trigger activates
A passive thermal sensor embedded in the eave soffit detects radiant heat above 200°F — the threshold at which ember ignition becomes probable. No power required. No network connection. No human action. The trigger is mechanical and fails safe: if it misfires, the blanket deploys and the home is protected.
Blanket unfurls in under four minutes
Compressed ceramic-aerogel panels release sequentially from the eave channel, unfolding downward to cover fascia, soffits, exterior wall cladding, and window frames. The deployment sequence is gravity-assisted and requires no electricity. Full coverage of a standard 2,400 sq ft roofline completes in under four minutes.
Reflective cocoon holds at 3,500°F
The deployed blanket presents a continuous aluminized ceramic surface rated to 3,500°F direct flame impingement — the temperature of a fully involved wildfire front. Aerogel insulation beneath the reflective layer limits heat transfer to the structure. Ember intrusion through soffits and eave gaps — the primary ignition pathway in WUI fires — is eliminated.
Post-fire retraction and inspection
After the fire passes, the blanket retracts manually via a roofline access point. A visual inspection confirms panel integrity. Panels that sustained direct flame contact are replaced individually — the system does not require full reinstallation after a fire event. Replacement panels ship within 72 hours.

The material science
Why ceramic-aerogel.
Aerogel is the least thermally conductive solid material known — 15 times more insulating than fiberglass, 40 times more than mineral wool. Its nanoporous silica structure traps air at the molecular level, blocking heat transfer by conduction and convection simultaneously.
The ceramic face layer handles direct flame and radiant heat. Aluminized ceramic reflects up to 97% of incident radiant energy — the mechanism that keeps the structure below ignition temperature even when the blanket surface is glowing.
Together, the two layers address the three heat transfer modes that kill homes in wildfires: radiant heat from the fire front, convective heat from superheated air, and conductive heat through structural members. No single-layer product addresses all three.
