Catalog Applications
Trim & Moulding
Profile & surface planning
Milled for repeatable lines &
project-ready details.
A compact square profile for battens, screens and precise finish work. High-temperature thermal modification reduces the board’s moisture response compared with the same species untreated.
Finish & Maintenance Recommendations:
Choose a compatible exterior finish when color retention is desired, and confirm factory-prefinish options with the dealer. If left unfinished, the surface will gradually weather toward silver gray; timing and uniformity vary with exposure and detailing.
Lower moisture uptake helps reduce seasonal movement across board joints.
No added synthetic wood preservatives in the thermal process.
Reduced movement supports more predictable joints when the profile is installed correctly.
Available by consultation through Builders FirstSource Issaquah.
Profile & Installation Planning
Read the profile before
choosing the fastening method.
The 2026 catalog lists Thermo Ayous 2x2 S4S E4E as S4S E4E. This simplified view helps explain the board relationship; it is not a scaled CAD detail or a substitute for the current installation guide.
Square-edge S4S E4E
S4S/E4E boards do not inherently create a tongue-and-groove lock. Joint spacing, exposure and fastening belong to the project assembly.
Fastening is assembly-specific
Confirm fastener material, gauge, length, edge distance and placement for the selected profile and substrate. Concealed fastening should not be assumed for every SKU.
End match only where listed
Only the cataloged Thermo Ash 1x6 Plus and 5/4x6 products are identified as End Match. No universal off-framing rule or fixed waste reduction is claimed.
