ألواح الجبس جيبروك (Saint-Gobain) المقاومة للرطوبة من الدرجة (H1)

Saint-Gobain Gyproc Moisture Resistant H1 Gypsum Plasterboard is a strong, waterproof plasterboard designed for use in wet environments. It helps prevent damp and mould issues in interior walls and ceilings and is suitable for residential and commercial projects where moisture resistance and durability are important (e.g., bathrooms, kitchens, and utility areas).

The board measures 12.5 mm thick, 1200 mm wide, and 2400 mm long. It is designed to be moisture-resistant and provides additional protection against damp, mould, and mildew, while still delivering a smooth finish suitable for painting or wallpaper.

Gyproc H1 offers enhanced moisture resistance compared with standard plasterboard, helping to reduce swelling, warping, and deterioration in damp environments. This makes it a better choice for areas exposed to moisture and humidity.

Ideal for interior walls and ceilings in bathrooms, kitchens, utility rooms, basements, and other damp environments where moisture resistance and durability are beneficial.

Install using standard drylining methods: cut the board to size, fix with corrosion-resistant gypsum/screw fixings at appropriate spacing (typically around 300 mm vertically, with edge supports as needed), and butt joints flush. Seal joints with a compatible jointing compound and tape, then sand smooth and finish with the desired decorative coating.

Use standard gypsum plasterboard jointing techniques. Apply fiberglass or paper joint tape over joints, embed in jointing compound, build up in thin layers, and sand for a smooth finish. This board is designed to receive common finishes such as plaster, emulsion paint, or wallpaper after proper sealing.

Gyproc H1 focuses on moisture resistance and durability for wet environments, with additional benefits in interior insulation. For higher fire or sound ratings, you may consider other Gyproc options designed specifically for fire resistance or acoustic performance (see product comparisons below).

Compared with Gyproc FireLine and Gyproc Standard plasterboards on Fepy, Gyproc H1 offers enhanced moisture resistance suitable for damp areas. For higher fire resistance, you might choose Gyproc FireLine; for general purpose use (no special moisture resistance), Gyproc Standard is appropriate. See the product pages for details: Gyproc FireLine (https://fepy.com/product/gyproc-fireline-plasterboard-12-5mm-1200x2400), Gyproc Moisture Resistant Plasterboard (https://fepy.com/product/gyproc-moisture-resistant-plasterboard-12-5mm-1200x2400), Gyproc Standard Plasterboard (https://fepy.com/product/gyproc-standard-plasterboard-12-5mm-1200x2400).

Use corrosion-resistant gypsum screws designed for plasterboard, jointing compound, and tape for seamless joints. For moisture-prone areas, consider moisture-resistant sealants and proper backing where needed. Always follow the fixing and finishing guidelines provided with your plasterboard system.

Yes, Gyproc H1 provides reliable moisture resistance and durability that are well-suited for damp-area installations, potentially reducing maintenance and repair costs over time. When comparing, consider the specific moisture, fire, and acoustic needs of your project and weigh against alternatives like Gyproc FireLine (higher fire resistance) or Gyproc Standard (general purpose).

Wear appropriate PPE (gloves, eye protection, and a dust mask when cutting). Handle boards carefully to avoid damage, follow safe lifting practices, and ensure proper ventilation in work areas. Store boards flat to prevent bowing and follow all local building codes and manufacturer guidelines during installation.

Keep humidity levels within a typical indoor range, ensure good ventilation, promptly address any water ingress, and use appropriate finishes and sealants as recommended for moisture-resistant boards. Regularly inspect joints and fixings and repair any damage to prevent moisture intrusion.
