Top 10 Companies in the Indoor Water-Resistant Gypsum Board Market (2026): Market Leaders Powering Global Construction

MARKET INSIGHTS

Global indoor water-resistant gypsum board market size was valued at USD 9.8 billion in 2025. The market is projected to grow from USD 10.5 billion in 2026 to USD 16.2 billion by 2034, exhibiting a compound annual growth rate of 5.6% during the forecast period.

Indoor water-resistant gypsum board is a specialized drywall engineered for interior spaces that experience elevated humidity. The boards are constructed by encasing a fire‑resistant gypsum core within moisture‑resistant face and back papers, often treated with silicone or other water‑repellent additives. This construction delivers superior protection against moisture, mold, and mildew compared to standard gypsum boards, making the product ideal for bathrooms, kitchens, laundry rooms, and basements.

The market expansion is largely driven by the growth of the global construction industry, especially in the residential and commercial sectors. Stringent building codes that mandate moisture‑resistant materials in wet areas, coupled with a rising consumer focus on healthier indoor air quality through mold prevention, are significant catalysts. Key industry players are continuously innovating; for instance, Saint‑Gobain has recently launched advanced formulations with enhanced mold resistance. Other major players—Knauf, Georgia‑Pacific, and USG Boral—hold a combined market share that is growing as they expand production capacities, particularly in the rapidly developing Asia‑Pacific region.
