Fiberon Sanctuary Composite Deck Board vs TimberTech Terrain+ Composite Decking

Both are capped composite boards that skip sanding, staining and sealing. Fiberon Sanctuary uses a three-sided PermaTech cap and comes in a grooved profile built for hidden fasteners, so it suits a full deck with a clean, fastener-free surface. TimberTech Terrain+ caps all four sides, including the grooves, and its scalloped underside makes boards lighter to carry and install. Owners of both report boards that hold color and resist moisture; Sanctuary's three-sided cap leaves the bottom face less protected, which matters more in wet or shaded sites.

• Choose the Fiberon Sanctuary if you want a grooved board that pairs with hidden fasteners for a smooth deck surface and a multi-tonal hardwood look.
• Choose the TimberTech Terrain+ if you want four-sided moisture protection and lighter boards for easier handling on a natural white oak look.
