Product description
Product Name
Knauf Water-Resistant Paper-Faced Gypsum Board
Product Overview
Knauf Water-Resistant Gypsum Board is a lightweight, moisture- and water-resistant panel developed specifically for humid environments. Its high-strength facing paper undergoes specialized treatment with organic waterproofing materials, significantly improving water resistance and hydrophobic performance.
Key Features
- Moisture and mold resistant: Specially treated facing paper helps prevent walls and ceilings from yellowing or darkening in humid conditions.
- Excellent dimensional stability: Minimal deformation helps maintain the integrity of walls, ceilings and finished joints.
- Low moisture expansion: Moisture expansion rate below 0.015%, approximately one-tenth that of calcium-silicate cement boards, which may reach 0.13%.
- Low water absorption: Breathable board structure dries quickly and reduces cracking caused by humidity changes.
- Reliable wet-season installation: The surface resists moisture penetration, helping maintain the quality of plastering and painting.
- Versatile substrate: Can serve as a backing board for ceramic tiles, metal panels and plastic decorative panels.
Applications
Suitable for hot and humid regions and environments with relative humidity up to 95%, including bathrooms, kitchens and basements.
It can be used for partition walls, suspended ceilings and wall-lining systems, as well as a substrate for ceramic tiles and decorative panels.
