Gyproc Glasroc H Board 12.5 mm – Water & Mold-Resistant Gypsum Plasterboard

Gyproc Glasroc H Board 12.5 mm – Water & Mold-Resistant Gypsum Plasterboard

The Gyproc Glasroc H Board is an advanced gypsum plasterboard engineered for environments exposed to moisture, humidity, and wet-area conditions. Manufactured using Enhanced Glass Reinforced Gypsum (eGRG) technology, this board features a reinforced gypsum core encased in hydrophobic treated glass mat liners that deliver excellent water resistance, low water absorption, and superior mold resistance. :contentReference[oaicite:2]{index=2}

Unlike standard gypsum boards, Glasroc H retains structural integrity even in damp conditions and provides a reliable substrate for tile, marble, or granite finishes without the need for traditional waterproofing layers. With low total water absorption (< 5 %) and surface water absorption performance, it offers exceptional durability in areas like bathrooms, kitchens, indoor pool ceilings, and corridors. :contentReference[oaicite:3]{index=3}

Key Features:

• Water-resistant gypsum board: Special hydrophobic glass mat liners reduce water ingress and enhance durability in wet environments. :contentReference[oaicite:4]{index=4}
• Mold resistance: Core contains biocides and glass-mat construction scores 10 on ASTM D3273 for best mold resistance. :contentReference[oaicite:5]{index=5}
• Strong backing for heavy finishes: Supports heavy tiling, marble, or granite up to 60 kg/m² with the right adhesive. :contentReference[oaicite:6]{index=6}
• Dimensional stability: Maintains strength and flatness even under moisture exposure. :contentReference[oaicite:7]{index=7}
• Dual surface design: Blue pre-primed glass mat exterior and white glass mat interior for superior finishing. :contentReference[oaicite:8]{index=8}
• Fast and easy installation: Lighter than cement boards with easier cutting and fixing installation. :contentReference[oaicite:9]{index=9}

Applications:

• Wet and moisture-prone interior walls and ceilings
• Bathrooms, shower enclosures, and kitchens
• Indoor swimming pool ceilings
• Heavy cladding backing with tiles or stone finishes
• Commercial and residential wet-area partitions

Gyproc Glasroc H Board is ideal for applications where water resistance and long-term performance are critical. Its engineered gypsum core and glass mat reinforcement create a robust yet lightweight board that outperforms standard gypsum boards in moisture-rich environments. :contentReference[oaicite:10]{index=10}
