CGC Durock Cement Board - 1/4" x 3' x 5'
CGC Durock Cement Board (1/4" x 3' x 5') is a mold‑ and moisture‑resistant tile underlayment engineered for floor and countertop applications. Its durable cement-based core, reinforced with a glass‑fiber mesh, provides a stable and long‑lasting substrate that won’t warp, swell, rot, or delaminate when exposed to moisture—making it a preferred choice for tile installations in both residential and commercial environments.
Designed to minimize height transitions between flooring materials, the 1/4‑inch thickness is ideal when joining tile to adjacent surfaces such as carpet or hardwood flooring, reducing the need for additional trim pieces. The board features smooth edges, square‑cut ends, and both smooth and rough surfaces—allowing installers to select the best side for their chosen bonding method.
Key Features
- Moisture‑ and mold‑resistant cement board, ideal for high‑humidity environments and tile‑ready surfaces.
