VG Cedar
vs. Thermo.

Vertical Grain Cedar is a premium visual selection valued for straight grain and naturally durable heartwood. Grade, heartwood content, moisture and current supply all matter in Issaquah sourcing.

Thermally modified profiles beside natural wood profiles for the VG Cedar guide in IssaquahVG Cedar
WHY IT IS SPECIFIED

Naturally durable heartwood and a long architectural track record in the Pacific Northwest.

WHAT TO DEFINE

Confirm the grade rules behind “VG,” the proportion of heartwood and sapwood, board width, moisture condition and whether appearance matching is required across elevations.

ISSAQUAH DESIGN CONTEXT

Architects consider VG Cedar for high-visibility cladding, soffits and trim where a consistent linear grain is central to the design.

Longer service starts with moisture

Why Thermo can
stay sound longer.

Cedar heartwood can already be naturally durable, so every decision should compare the exact products rather than assume a universal winner. Maximo becomes compelling when stability, installed weight, a defined profile and documented warranty matter alongside durability.

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.

LOWERmoisture response

Less moisture uptake means reduced dimensional movement compared with the same wood before modification.

MOREbiological resistance

The heat-and-steam process changes wood chemistry in ways that improve resistance to decay organisms.

20-YEARlimited product warranty

Maximo documents a product warranty; eligibility still depends on its terms, application and installation requirements.

REAL WOODno added preservatives

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 makes a product-level value proposition: controlled heat-and-steam modification, lower moisture movement, profile-specific catalog choices and a 20-year limited product warranty.

Traditional material
Performance and price depend strongly on grade, heartwood content, moisture and market availability.
Maintenance discussion
Color retention requires a maintained finish; uncoated material naturally weathers 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 VG 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. VG Cedar performance still depends on grade, heartwood, moisture, protection and detailing.

What makes Maximo Thermo different from VG 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.

Where can I ask about Maximo Thermo near Issaquah?+
