Fire-Protective Coating
Non-Sacrificial Fire Protection for Critical Timber Infrastructure
Wildfire Shield is a non-sacrificial fire mitigation coating that acts as a high-temperature thermal barrier — shielding timber utility poles, bridges, and railroad infrastructure from wildfire damage.
- ASTM E119 fire-resistance rated
- Flame Spread 0, Smoke Development 0 (ASTM E84)
- Designed for DOT, utility, and rail infrastructure
- Spray or brush application
- Consult NanoTech Materials for recoat intervals

Wildfire Threatens the Infrastructure You Cannot Replace Quickly
The Western US alone has over 180 million timber utility poles, thousands of rail trestles, and countless bridge timbers — all vulnerable to wildfire. A single fire season can destroy years of capital investment and leave communities without power, transit, or connectivity for months.
Traditional fire protection for timber — cementitious wraps, concrete encasement, or metal shielding — is expensive to install, difficult to inspect, and often traps moisture that accelerates rot. These methods protect against fire but introduce new failure modes.
Wildfire Shield takes a different approach. It uses high reflectance, high emissivity, and low thermal conductivity to directly protect substrates and reduce heat transfer from impinging flames and radiant heat — without sacrificing the coating in the process.
How Wildfire Shield Protects Timber
Non-sacrificial thermal barrier technology — always protecting.
Thermal Barrier Protection
Wildfire Shield uses high reflectance, high emissivity, and low thermal conductivity to directly protect substrates and reduce heat transfer from impinging flames and radiant heat.
ASTM E119 Rated
Tested per ASTM E119 (Standard Test Methods for Fire Tests of Building Construction and Materials) to demonstrate fire-resistance performance on timber substrates.
Weather Resistant
Wildfire Shield is designed to withstand outdoor exposure on timber infrastructure across a wide range of environmental conditions.
Visual Inspectability
The white finish (custom colors available) allows inspectors to visually assess poles and structures without removing cladding.

Application Process
Site Assessment
Our team evaluates the timber substrate, environmental conditions, and access logistics for your infrastructure.
Surface Preparation
Timber is cleaned and dried. Loose bark, dirt, and debris are removed to ensure proper adhesion.
Coating Application
Wildfire Shield is applied via airless spray or brush at the specified thickness. Consult application guide for surface preparation requirements.
Inspection & Documentation
Dry film thickness is verified and documented. You receive application records and maintenance guidelines.
