Product Summary
Construction and Materials
This product from National Gypsum Company falls within the Walls & Finishes category, specifically as a type of backerboard. These products are designed for use as underlayment and substrate in various construction applications, particularly in areas prone to moisture.
The construction of these backerboards typically involves a core material designed for stability and moisture resistance, faced with materials that provide a suitable surface for finishes. While specific details on construction for every product within the "Walls & Finishes (Tile Backerboard, Cement Board, Backerboard Underlayment, Insulated Cement Board)" category are not universally uniform across all offerings, common characteristics can be inferred from the product types listed.
Materials Used:
- Cement Board: This type of backerboard is primarily composed of cementitious materials, including Portland cement, aggregate (like sand or perlite), and often reinforcing fibers (such as fiberglass). This composition makes it highly resistant to moisture, mold, and mildew, which is crucial for applications behind tile in wet areas like bathrooms and kitchens.
- Gypsum Core (for some backerboards): Certain backerboards, especially those designed for drywall applications or as a substrate for other finishes, may utilize a gypsum core. These are often treated or coated to enhance moisture resistance, differentiating them from standard drywall.
- Facing Materials: The core material is typically faced with a reinforcing mesh, often fiberglass, embedded in a cementitious coating. This facing provides strength, dimensional stability, and a surface that accepts thin-set mortar or other adhesives effectively.
- Insulation (for Insulated Cement Board): For insulated cement board products, an additional layer of insulation is incorporated into the construction. This insulation is typically a rigid foam core, such as expanded polystyrene (EPS) or extruded polystyrene (XPS), sandwiched between cementitious facings. This provides both a substrate for finishes and thermal insulation.
The primary function of these backerboards is to provide a stable, durable, and moisture-resistant substrate for finishing materials like tile, stone, or other wall coverings. Their construction is engineered to prevent the transfer of moisture to underlying building structures, thereby mitigating the risk of mold growth and structural damage.
