Our most common recommendation for this climate. It resists moisture, doesn't feed termites, and holds up through Louisiana summers without warping.
A budget-friendly option that handles rain well, though it can soften or warp in intense heat and doesn't offer the same termite or storm performance as fiber cement.
We'll install it if that's the look you want, but we'll also be honest that Louisiana's humidity and termite pressure make it the highest-maintenance choice of the three.
