Why choose
Thermo wood?
For siding, soffits, decking and architectural trim, the useful question is not whether every traditional wood is bad. It is whether a defined Maximo profile gives the project a more predictable path to stability, durability and maintenance.

Why it can last longer
Control the conditions
that shorten wood life.
Moisture movement and biological attack are two recurring durability concerns in wood assemblies. Controlled thermal modification changes how the material responds to both—before it arrives on the project.
Lower moisture response
Thermal modification lowers equilibrium moisture content. Compared with unmodified material, the wood takes up less moisture and moves less as humidity changes.
Improved stability
Reduced swelling and shrinkage help profiles hold their intended rhythm across cladding, ceilings, soffits, decking and trim.
Enhanced biological durability
Heat changes moisture behavior and available nutrients, improving resistance to wood-decay organisms without adding synthetic preservatives.
A documented product
Maximo connects species, nominal size, profile, application guidance and a limited warranty—more information than a species name alone provides.
Heat & dry
Steam and hot air reduce moisture before the wood reaches the modification phase.
Controlled heat
Elevated temperature changes the wood structure without pressure-impregnated preservatives.
Cool & balance
The material is cooled and conditioned before machining into defined architectural profiles.
Drag to compare
Defined profile.
Natural variation.

Each local guide explains what the traditional wood does well, what variables must be controlled and where a Maximo profile can offer a more predictable product choice.
01
ISSAQUAH WOOD GUIDE
→02Vertical Grain Hemlock
Natural durability is limited without protection, and movement follows changing moisture conditions.
ISSAQUAH WOOD GUIDE
→03Vertical Grain Cedar
Performance and price depend strongly on grade, heartwood content, moisture and market availability.
ISSAQUAH WOOD GUIDE
→04Western Red Cedar
Durability varies with heartwood and sapwood content; grade, moisture and supply influence the installed result.
ISSAQUAH WOOD GUIDE
→Douglas Fir
Untreated material is not naturally durable enough for every exterior exposure and responds to moisture cycling.
Choose by application
One process.
Twenty-one profiles.
Product suitability is profile-specific. Start with the application, then choose the Maximo species, size and face that match the assembly.
The honest specification
Better for the right job.
Not magic wood.
Thermally modified wood is generally intended for documented architectural applications, not as an automatic structural replacement. It still needs correct storage, acclimation, ventilation, drainage, fastening and finish planning.
Traditional Cedar, Hemlock and Douglas Fir can all be appropriate. The Maximo advantage is strongest when the project values reduced moisture movement, enhanced durability, low weight, repeatable profiles and a published warranty.

Issaquah Thermo FAQs
Better decisions
start here.
Does thermally modified wood last longer in Issaquah?+
It can in compatible applications because thermal modification lowers moisture response and improves biological durability. Actual service life still depends on product selection, exposure, drainage, ventilation, fastening, finish and maintenance.
Is Maximo Thermo maintenance-free?+
No real exterior wood is maintenance-free. A UV-protective finish is required to retain the original brown tone; otherwise the surface naturally weathers gray. Follow the Maximo installation and maintenance guide.
Can Maximo Thermo replace structural Douglas Fir?+
Do not assume that it can. Thermal modification can reduce some mechanical properties. Use Maximo profiles only for the applications documented in the catalog and involve the project professional for structural decisions.
