Key advantages &
installation rules.
Uniform Color & Grain
Consistent light chocolate tone with straight, subtle wood grain.
Clean Joint Lines
Cataloged edges create a defined pattern when installed over a level, correctly spaced support plane.
Assembly Guidelines for Ceilings & Soffits:
- Blind nail through the tongue into ceiling furring strips.
Reduced tangential movement supports more consistent joints through seasonal changes.
Thermal modification reduces moisture uptake and changes nutrients used by decay fungi; confirm the rating for the selected profile.
Real wood modified without added wood-preservative chemicals.
