Sill‑Rite vs. Drywall and MDF
Neither drywall nor MDF were intended to protect against moisture. Made of organic materials, both drywall and MDF simply provide food for mold. Sill–Rite sills are made entirely of vinyl—a non-organic material—that mold can't feed on. Also, when installed properly, Sill‑Rite sills prevent moisture from seeping into the walls.
Sill‑Rite sills are not only insurance against mold, they are attractive and durable. Made from cellular PVC, Sill–Rite sills won't yellow, blister, flake, or peel. The surface is smooth and easy to clean. Plus, Sill‑Rite sills look great and give your homes a distinctive flair.

Attractive, Durable & Affordable

The three exposed edges are finished* with one of two profiles. Installation is quick and easy—just four simple cuts with standard wood finishing tools.
