Key advantages &
installation rules.
Authentic Nordic Grain
Tight annual growth rings with round sound knots create organic Scandinavian warmth.
Reduced Resin Movement
High-temperature processing reduces volatile pitch compared with untreated pine.
Assembly Guidelines for Siding & Cladding:
- Install over a drained rainscreen cavity with minimum 3/4" depth.
- Use stainless steel fasteners with ring shanks for maximum withdrawal resistance.
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.
