People Usually Ask
Where can I buy?
Maximo Thermo BurnBlock is stocked with dealers throughout California, including coverage near the areas hit hardest by wildfire. Request a quote above and a specialist will point you to the right dealer for your project.
What are lead times for California orders?
Lead times vary by project scope. Get in touch with our concierges to get a timeline right away!
Does BurnBlock meet California's ASTM E84 Class A requirement for WUI zones?
Yes. Maximo Thermo Ayous BurnBlock carries a Class A fire rating under ASTM E84 and has passed CSFM 12-7A-1 wildfire exposure testing
Can architects include BurnBlock in a spec without a proprietary spec?
Absolutely. BurnBlock specs cleanly as a performance-based product
Does treatment affect the structural properties of the wood?
Not a bit. BurnBlock is impregnated at the cellular level, not a surface coating, so every board keeps its full machinability.
What wood species are available for BurnBlock treatment in California?
Ayous. We chose it deliberately: a naturally durable, lightweight wood that takes BurnBlock's cellular-level protection exceptionally well, giving you a refined, consistent look backed by real fire test data.
