The Envello Shadow Line+ siding board is molded from real oak masters and designed to perfectly replicate smooth timber with a flat grained finish, giving a clean authentic look. The increased width of the Shadow Line+ board compared to standard wooden boards means there is larger grain detail. This gives an enhanced visual impact, without risk of the board twisting or warping over time.
Shadow Line+ siding boards are certified for use in WUI zones, per CalFire. They have been tested to ASTM E84, and have a Class A flame spread rating*
