Cerlos Fire-Resistant Building Materials (2026)

23/09/2026

Termites won't chew through this wood.

That's because it's mineralized. CERLOS® is made from forestry waste, and our proprietary process seals every fibre in mineral, so it's no longer a food source.

The finished material still cuts and nails like wood, and it is Class A fire rated.

The problem it answers is a large one. Termites cause an estimated $6.8 billion in U.S. property damage every year, according to the National Pest Management Association, and standard homeowners insurance almost universally excludes it.

Exterior siding will be the first CERLOS product. It will be followed by 4x8 sheathing panels, slate looking roofing tiles, and more products to come from the same proprietary technology.

Ninety-four percent of new single-family homes completed in the U.S. last year were wood-framed. That is not an outlier, that is how the country builds.

Every fire season the same argument comes back. Stop building with wood. Build with concrete. Concrete does not burn.

It is a fair point. It is also not going to happen, and the reason is worth understanding.

Wood on this continent has been abundant, cheap and easy to work for two centuries. That is what let builders put up millions of homes quickly and affordably, and a hundred years of trades, tooling, codes, lenders and framing crews grew up around that one material.

𝗕𝘂𝗶𝗹𝗱 𝗮𝗳𝗳𝗼𝗿𝗱𝗮𝗯𝗹𝘆 𝗮𝗻𝗱 𝗾𝘂𝗶𝗰𝗸𝗹𝘆, 𝘄𝗶𝘁𝗵 𝘁𝗵𝗲 𝗰𝗿𝗲𝘄𝘀 𝗮𝗻𝗱 𝘁𝗼𝗼𝗹𝘀 𝘁𝗵𝗲 𝗶𝗻𝗱𝘂𝘀𝘁𝗿𝘆 𝗮𝗹𝗿𝗲𝗮𝗱𝘆 𝗵𝗮𝘀.

Every fire season we are reminded what that trade costs. Every rebuild makes the same pick anyway, because the other side of it was never really on the table.

𝗕𝗨𝗧 𝗗𝗢 𝗪𝗘 𝗛𝗔𝗩𝗘 𝗔𝗡𝗬 𝗔𝗟𝗧𝗘𝗥𝗡𝗔𝗧𝗜𝗩𝗘𝗦?

Yes. And it does not ask anyone to stop building the way they already build.

CERLOS® is a new fire-resistant building material. Not a fire-resistant coating or treatment, just mineralized wood fiber throughout. Let us explain. The process fills the pores of the fiber itself with inorganic mineral, so the change goes all the way through. It is the same mechanism that makes petrified wood. We fill the pores and keep the fiber. Handles like wood. Holds up like rock.

𝗡𝗼 𝗿𝗲𝘀𝗶𝗻𝘀. 𝗡𝗼 𝗴𝗹𝘂𝗲𝘀. 𝗡𝗼 𝗵𝗶𝗴𝗵 𝗵𝗲𝗮𝘁.

✓ Class A fire-rated (ASTM E2768). It does not ignite.
✓ Mold-resistant (Tested to G21)
✓ All-weather stable (ASTM C1186)
✓ Cuts and nails like lumber, with the tools every crew already owns
✓ Made from forestry waste, at the price of ordinary lumber

It keeps everything that made wood the default for a hundred years but removes the one property we keep paying for.

𝗖𝗘𝗥𝗟𝗢𝗦®: "𝗣𝗘𝗥𝗛𝗔𝗣𝗦 𝗧𝗛𝗘 𝗠𝗢𝗦𝗧 𝗗𝗜𝗦𝗥𝗨𝗣𝗧𝗜𝗩𝗘 𝗠𝗔𝗧𝗘𝗥𝗜𝗔𝗟 𝗦𝗜𝗡𝗖𝗘 𝗣𝗟𝗔𝗦𝗧𝗜𝗖."

As mentioned on the Construction Disruption Podcast in November 2024.

Here is the process behind it.

𝗪𝗛𝗔𝗧 𝗠𝗜𝗡𝗘𝗥𝗔𝗟𝗜𝗭𝗔𝗧𝗜𝗢𝗡 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗜𝗦

A deep-tech process that takes wood fiber and develops an inorganic, ceramic-like material inside the cells themselves. The pores of the fiber are filled with inorganic mineral at the cellular level.

The result is a hybrid material with the workability of wood and the durability properties of rock.

𝗪𝗛𝗔𝗧 𝗚𝗢𝗘𝗦 𝗜𝗡

Sawdust. Mill scrap. Forest floor waste. Agricultural scrap. Any lignocellulosic scrap fiber works as an input.

No resins. No glues. No high heat.

Forest floor waste is wildfire fuel load. We take it out of the forest and turn it into the thing that resists fire on the wall.

𝗪𝗛𝗔𝗧 𝗖𝗢𝗠𝗘𝗦 𝗢𝗨𝗧

✓ Class A fire-rated (ASTM E2768)
✓ Mold-resistant (Tested to G21)
✓ All-weather stable (ASTM C1186)
✓ Zero carcinogens, no formaldehyde, no silica dust, no resins
✓ 100% recyclable, or usable as plant fertilizer at end of use
✓ Cuts and nails like lumber, with the tools every crew already owns
✓ Costs about the same as ordinary lumber

𝗪𝗛𝗬 𝗜𝗧 𝗜𝗦 𝗡𝗢𝗧 𝗘𝗔𝗦𝗬 𝗧𝗢 𝗖𝗢𝗣𝗬

✓ $30M+ invested in R&D over 15+ years
✓ 6 patents, 4 filed and 2 to be filed
✓ Trade secrets around the process chemistry

A new material platform is not something you reverse engineer from a sample.

Someone asked us here on Facebook: "So is that petrified fossil wood?"

No. But they were onto the right idea.

𝗛𝗢𝗪 𝗣𝗘𝗧𝗥𝗜𝗙𝗜𝗘𝗗 𝗪𝗢𝗢𝗗 𝗔𝗖𝗧𝗨𝗔𝗟𝗟𝗬 𝗙𝗢𝗥𝗠𝗦

Mineral-rich groundwater seeps into buried wood and crystallizes inside the cell pores. The wood hardens from the inside out. It takes centuries at the very fastest, usually far longer.

𝗪𝗛𝗔𝗧 𝗪𝗘 𝗗𝗢

The same thing, on purpose, in minutes.

CERLOS® does not coat wood fiber. It mineralizes it. The process fills the pores of the fiber with inorganic mineral, creating a hybrid material with the workability of wood and the durability of rock.

Most building products take the other route. Coatings, resins, additives, surface treatments. Scratch it, cut it, or weather it long enough and you are back to whatever is underneath.

There is no underneath here. The change goes all the way through.

𝗧𝗛𝗘 𝗢𝗡𝗘 𝗗𝗜𝗙𝗙𝗘𝗥𝗘𝗡𝗖𝗘 𝗧𝗛𝗔𝗧 𝗠𝗔𝗧𝗧𝗘𝗥𝗦

Petrified wood keeps the look of wood, right down to the grain. But there is no wood left in it. The fiber is gone and quartz is standing in its place. That is why it is stone, and why it shatters instead of taking a nail.

We fill the pores and keep the fiber. So it still cuts and nails like lumber, with the tools every crew already owns.

✓ Class A fire-rated (ASTM E2768)
✓ Mold-resistant (Tested to G21)
✓ All-weather stable (ASTM C1186)
✓ Zero carcinogens, no formaldehyde, no silica dust, no resins

Handles like wood. Holds up like rock.

𝗧𝗛𝗘 𝗙𝗥𝗔𝗠𝗜𝗡𝗚 𝗪𝗔𝗦 𝗖𝗢𝗩𝗘𝗥𝗘𝗗 𝗜𝗡 𝗠𝗢𝗟𝗗.

An Idaho home inspector posted a 91-second clip this spring from a pre-drywall inspection of a new-construction home.

He points to multiple framing components with visible growth and explains the response he routinely gets on jobsites: "It's just part of the build process. We're not doing anything about it."

He's been yelled at on site for raising the issue. His clients call him asking what he can do. His honest answer is the same one he gives the builders: he'll put it in the report. After that, it's between the builder and the clients.

𝗦𝗢 𝗛𝗘 𝗖𝗛𝗔𝗡𝗚𝗘𝗗 𝗧𝗔𝗖𝗧𝗜𝗖𝗦

He swab-tested a representative patch of the visible mold and paid for the lab analysis himself. A positive lab result attached to the inspection report gives the clients the evidence they need to push back.

In his words, it will "force the builder to actually go through and clean this house."

𝗧𝗛𝗘 𝗟𝗔𝗕 𝗥𝗘𝗦𝗨𝗟𝗧

Sample T260451-01. Client description: Lumberyard Mold on Framing.
Direct Exam Mold Analysis, qualitative 1-5 scale (Very Low to Very High):

▪ Dirt & Debris: 1 (Very Low)
▪ Hyphal Fragments: 4 (High)
▪ Determined Mold Activity: 𝗔𝗖𝗧𝗜𝗩𝗘 𝗠𝗢𝗟𝗗 𝗚𝗥𝗢𝗪𝗧𝗛

His closing line: "So now the builder must do something about it."

𝗪𝗛𝗬 𝗧𝗛𝗜𝗦 𝗞𝗘𝗘𝗣𝗦 𝗛𝗔𝗣𝗣𝗘𝗡𝗜𝗡𝗚

Wood lumber arrives at the jobsite already a food source for mold. Moisture finds it. Spores find it.

The builder's pushback is uncomfortably accurate, because lumberyard mold has been normalized by an industry that accepted an organic structural material as the default.

A lab result forces remediation on one house. It does not change the underlying material choice.

𝗧𝗛𝗘 𝗠𝗔𝗧𝗘𝗥𝗜𝗔𝗟 𝗔𝗡𝗦𝗪𝗘𝗥

At MOXY OID, we built CERLOS® to remove this failure mode entirely. CERLOS® is a mineralized inorganic building panel. There is no organic content for mold to consume. The substrate itself is not a food source.

✓ ASTM G21 · mold and fungi resistance
✓ ASTM C1186 · water stability
✓ ASTM E2768 · Class A fire performance

The structural fix is not a more aggressive inspector.

Three forces are now converging on fire-resistant building materials. None of them are going away.

Force 1: Building codes.
Research tracking 55,408 homes across 18 years found that fire-resistant construction mandates reduce home loss probability by 40%. California Chapter 7A, Oregon’s local adoptions, and the International Wildland-Urban Interface Code are all tightening. Every new WUI home built anywhere in the country must meet these standards. Every rebuild after a wildfire must too.

Force 2: The insurance market.
The California FAIR Plan now carries more than $450 billion in exposure. Major carriers have exited or dramatically reduced coverage in WUI zones. What’s replacing underwriting criteria based on location? Material quality. Homes with fire-resistant cladding qualify for premium discounts of 5 to 20 percent or better. The insurance market is now actively pricing material choice.

Force 3: ESG capital requirements.
Building materials account for 11% of global carbon emissions, according to the UN Environment Programme. Institutional investors are now requiring Environmental Product Declarations. LEED v5 is tightening its materials criteria. The EU has already moved on construction carbon disclosure. The capital that funds large-scale development is asking different questions about what goes into buildings.

Each of these forces creates independent demand. Together, they create a structural floor under the fire-resistant materials category.

The fire-resistant building materials market was valued at $4.83 billion in 2025 and is projected to grow at 5.9% annually through the decade. That growth isn’t driven by one bet. It’s driven by three separate, compounding regulatory and market pressures.

That’s not a niche. That’s a category being built by policy, insurance, and capital simultaneously.

80 seconds. That's how long it takes for flames from one building to ignite a wall 6 feet away.

No direct contact. No dramatic fire front. Just radiant heat and flame exposure, and 80 seconds to ignition.

This is not a model prediction. This is IBHS laboratory research (Maranghides and Johnsson, 2008, cited by IBHS 2023). In controlled testing, window flames jetting from one structure ignited a mock wall assembly 6 feet away in 80 seconds. In still air. With no wind.

Now add 60 mph Santa Ana winds. Add months of drought. Add 44,000 displaced residents. Add a neighborhood of homes built with combustible siding in the 1950s.

You get Altadena in January 2025.

The science says: your walls are not passive. They are either fuel or they are not. Combustible siding in a WUI community is not just a risk to your home, it is a countdown timer for the home next to it.

IBHS states it directly: "Surface flame spread on combustible siding occurs quickly... this exposes windows and eaves to direct flame contact and can begin the cascade of damage for a home." (IBHS, Home Mitigations That Matter, April 2023)

CERLOS Siding is Class A fire-resistant (ASTM E2768). 30 minutes of sustained flame and heat. No progressive combustion. Remove the ignition source, the burning stops. The cascade doesn't start.

What's on your walls matters. Everything downstream depends on what happens in those first 80 seconds.

MOXY is working to bring CERLOS into production in the United States. We have filed 5 patents protecting this process and raised $11M. To learn about manufacturing partnership opportunities, contact CEO Robert Bedard: [email protected] / 725-306-0414.

Wood rots. Drywall absorbs moisture. Paper-faced products feed mold spores.
There's a building material that starves them.

Mold needs two things to grow: moisture and organic food. The EPA confirms it thrives on "virtually any organic substance," and most buildings are full of it. Wood framing, paper-backed gypsum, cellulose insulation. Every one of them is a buffet.

The result? The CDC links indoor mold exposure to respiratory symptoms, asthma attacks, and lung infections in immune-compromised people. The WHO's 2009 guidelines flagged early mold exposure as a risk factor for childhood asthma development. This isn't cosmetic. It's a health problem hiding inside walls.

For builders, it's also a cost problem. Mold remediation claims run $10,000 to $30,000 per incident, and they often surface years after construction. One callback can wipe out the margin on an entire project.

CERLOS takes a different approach. The mineralization process converts organic wood fiber into an inorganic matrix. No organic food source means mold has nothing to consume. No chemical treatments. No coatings that wear off. The material itself is inhospitable to mold, mildew, and fungus.

It also resists water absorption, so the moisture half of the equation is handled too. No swelling, no warping, no rot.

One material that removes both conditions mold needs to survive.

And it's still Class A fire-rated (ASTM E84), termite-resistant, UV-stable, and installs with standard carpentry tools.

No special blades. No silica dust. No respirator required.
A fire-resistant panel that works like wood.

That's CERLOS.

Cuts with the standard carpentry saw already on your truck. Fastens with hammers, air nailers, and drills. Accepts screws, nails, and staples. Paints with whatever's on the shelf.

If you've ever worked with fiber cement, you know the drill: special diamond-tipped blades, mandatory N-95 respirators, no mechanical cutting indoors. The CDC lists silica dust as the leading cause of occupational lung disease in construction. It's a serious safety burden every crew has to manage.

CERLOS doesn't create that problem. Zero silica content means zero silica dust. Your crew can cut, trim, and install without respiratory protection protocols slowing down the job.

But workability is only half the story.

CERLOS is Class A fire-rated (ASTM E84), won't ignite under test conditions, and produces zero toxic emissions during fire exposure. It resists water, mold, termites, UV, and freeze-thaw cycles. One material, multiple threats handled.

And it's made from 70% forestry and agricultural waste, material that would otherwise decompose or burn. The carbon from that waste stays locked in for the life of the building.

Fire-resistant. Worker-safe. Built to install like the materials your crew already knows.
