Sanctuary Decking

Sanctuary Decking

Beautiful and easy to maintain, Sanctuary decking makes your backyard a place to stay.
  • Bold, multi-tonal colors and rustic embossing. Board colors are complementary and pair well together, making them perfect for adding unique designs like picture-framing, borders and more.
  • Durable composite core resists splintering, rotting, cracking, insects and decay.
  • Three-sided PermaTech cap layer provides superior protection and fade resistance.
  • Boards never need sanding, staining or painting. Simply clean with soap and water or a mild cleaner.
  • Sanctuary contains 95% recycled material, combining recycled wood with the long-lasting resilience of recycled plastic.
  • The flat-profile bottom provides a sturdy feel, reminiscent of traditional lumber.
  • A Fire-rated version of Sanctuary decking is available, which helps resist damage from fire and reduce flame spread, providing added protection for the deck and home.
  • Backed by a 40-year performance, stain and fade warranty.
