Western Red Cedar
vs. Thermo.
Western Red Cedar has deep regional familiarity, light weight and naturally durable heartwood. Color, grain and durability vary across grades and between heartwood and sapwood.
Western Red CedarDefine grade, heartwood expectations, moisture, face quality, finish and acceptable color variation before comparing bids or approving samples.
Western Red Cedar remains a familiar reference for Issaquah-area siding, soffits, screens and exterior details—making it a useful baseline for product-level comparisons.
Longer service starts with moisture
Why Thermo can
stay sound longer.
Western Red Cedar heartwood is naturally decay resistant, but grade, heartwood content, detailing and exposure still influence service. Maximo offers a more controlled product story rather than relying on species name alone.
Thermal modification lowers equilibrium moisture content and reduces swelling and shrinkage. It also improves biological resistance. Those advantages do not replace correct design—but they reduce two of the conditions that commonly drive movement and decay.
Less moisture uptake means reduced dimensional movement compared with the same wood before modification.
The heat-and-steam process changes wood chemistry in ways that improve resistance to decay organisms.
Maximo documents a product warranty; eligibility still depends on its terms, application and installation requirements.
The modification process uses controlled heat and steam while preserving real-wood character.

Where Thermo changes the brief
Compare a species category
with a defined product.
Maximo Thermo should be evaluated profile by profile when predictable movement, lower moisture response, catalog consistency and a documented warranty are specification priorities.
- Traditional material
- Durability varies with heartwood and sapwood content; grade, moisture and supply influence the installed result.
- Maintenance discussion
- A finish is needed to preserve color, while unfinished boards weather to silver-gray.
- Maximo alternative
- Choose a species, size, profile and cataloged application before requesting local availability.
- Important limitation
- Thermal modification can reduce some strength properties. Use each Maximo profile only for its documented application; do not assume a structural substitution.

Does Maximo Thermo always last longer than Western Red Cedar?+
Not in every assembly or exposure. For compatible cataloged applications, thermal modification improves moisture behavior and biological durability, which can support longer service when the profile is detailed, installed and maintained correctly. Western Red Cedar performance still depends on grade, heartwood, moisture, protection and detailing.
What makes Maximo Thermo different from Western Red Cedar?+
Maximo products are thermally modified with controlled heat and steam, then offered as defined catalog profiles with published application guidance and a 20-year limited product warranty.
Does thermally modified wood require maintenance?+
Yes. A UV-protective finish is needed if the design intent is to retain the original brown tone. Uncoated wood naturally weathers, and every exterior assembly still needs drainage, ventilation and correct fastening.
