Make the wall the feature
Fine shadow lines create a warm, textured backdrop.
Think beyond one storey
A tall material plane draws the eye through the space.
Texture in the light
Changing light reveals the depth of the profile.
One continuous surface
The wall treatment carries across the door for a cohesive finish.
A warm backdrop
Wood anchors the room around its everyday focal point.
Change the direction
Contrasting board directions give the wall its own composition.
A quieter retreat
Natural texture softens a compact interior.
Frame the focal point
A vertical wood surface brings balance to the central feature.
Carry the material outside
Wood continues the material palette into an outdoor living space.
A line through the building
Repetition makes the journey through the building part of the design.
Wood, at room scale
Warm wall planes bring scale and continuity to the interior.
A room within a room

Bring us your inspiration ↗Material & application
From inspiration
to specification.
Thermally modified wood is real wood whose moisture response and biological durability have been changed by controlled heat and steam. Product, species and profile still matter.
Create an interior or protected architectural wall by defining board direction, joint profile, backing, fire requirements, transitions and how the material meets doors, millwork and ceilings.
Name the manufacturer, species, exact profile, cataloged application, fasteners, finish, storage and installation requirements.
A feature wall is a finish assembly, not a structural wall. Confirm substrate, furring, fastening concealment, tolerances and access to utilities before choosing the board.
Thermal modification can reduce some mechanical properties. Use only documented applications and do not assume an automatic structural substitution.
The prefinish advantage
Coat the board
before access disappears.
Maximo guidance recommends coating siding boards on all sides before assembly. Prefinish availability, coating, color and warranty must be confirmed for the selected profile. Prefinishing can lock in a more predictable tone before the wall is assembled and makes it easier to protect joints and edges that would be difficult to coat uniformly in place.
Plan a prefinished packageControlled coverage
Confirm whether faces, backs, edges and ends are included, plus coating manufacturer, color, sheen and target coverage.
Cleaner schedule
Move eligible coating work away from installed assemblies, ladders, lifts and interference with other trades.
Consistent appearance
Controlled application and cure conditions can reduce lap marks, streaks and unfinished shrink lines.
Field discipline remains
Reseal cuts, holes and damaged coating; protect finished boards in storage and follow the approved touch-up process.

Four questions
before material selection.
Confirm interior finish, fire, accessibility and code requirements for the occupancy. Thermal modification is not a substitute for an assembly review.

Material planning FAQs
Specify first.
Price second.
Is Thermally Modified Wood automatically the best choice for wood feature walls?+
No. Thermally Modified Wood has useful strengths, but the decision still depends on exposure, grade or product, profile, assembly, finish, maintenance and budget. This guide makes those inputs visible before a quote is requested.
Can Maximo Thermo be used for this wall project?+
Only when the exact profile is documented for the intended application. The profiles shown here are selected from the closest cataloged application, but the project team and BFS Issaquah should confirm the final profile and assembly.
Why discuss prefinishing before installation?+
Prefinishing can lock in a more predictable tone before the wall is assembled and makes it easier to protect joints and edges that would be difficult to coat uniformly in place. Prefinishing does not eliminate field-cut sealing, touch-up, installation care or future maintenance.
Where can I ask about availability in Issaquah?+
Submit the project brief through this site or contact Builders FirstSource Issaquah. This site does not claim live inventory, pricing or guaranteed lead time.
Technical sources & limitations
Product suitability, prefinish availability, coating compatibility, live inventory, pricing and lead time must be confirmed for the selected profile and project.
