Saint-Gobain Gyproc SoundBloc MR Plaster Board, 12.5X1200X2400MM, Acoustic with Moisture Resistant Board for Wet Rooms

Gyproc SoundBloc Moisture Resistant Plasterboard is a gypsum board with a moisture-resistant core and waterproof-faced liners. It’s designed for damp-prone interiors and aims to provide robust wall construction with optimized acoustic performance. The listing notes a sheet size of 12.5 × 1200 × 2400 mm and a thickness around 10.5 mm in the specifications.

Key specs include a moisture-resistant core, waterproof-faced paper liners, sheet size 12.5 × 1200 × 2400 mm, and a thickness listed as 10.5 mm in the technical notes. It’s engineered to deliver both strength for walls and improved sound insulation.

The board is designed to optimize sound insulation by absorbing and dissipating sound within the wall assembly, helping to keep internal noise down and reduce transmission from outside environments.

Use it in interior, damp-prone areas where you need both moisture resistance and reliable wall strength—such as bathrooms, kitchens, basements, laundry rooms, and other humidity-prone spaces.

General steps: prepare a clean, dry substrate; cut boards to fit; fix boards to studs with appropriate drywall screws, typically starting along the edges and spacing screws evenly; leave a small gap at joints; apply joint tape and plaster or joint compound; sand smooth; prime and finish with paint or tile as needed.

You’ll typically need a utility knife or drywall saw, tape measure, straight edge, drywall screws, a drill/driver, joint tape, joint compound, sanding block or screen, primer, and paint or tile adhesive for finishing.

Both are designed for moisture-prone areas, but SoundBloc emphasizes enhanced acoustic performance. For a direct product-to-product look, you can compare them here: https://fepy.com/product/saint-gobain-gyproc-moisture-resistant-plasterboard

Gyproc Standard Plasterboard is a general-purpose option and typically lacks the moisture resistance and enhanced acoustic performance of SoundBloc. If you’re choosing based on damp-prone spaces, SoundBloc is generally a better fit. See the standard option here: https://fepy.com/product/saint-gobain-gyproc-standard-plasterboard

Yes. It’s a gypsum-based board from Saint-Gobain Gyproc designed for interior use in damp environments. It’s formulated to be asbestos-free and suitable for indoor walls; always follow installation guidelines to maintain performance and safety.

You can finish with paint after priming, or tile over suitable surfaces with appropriate waterproof tile adhesive. For best results, seal joints with the recommended joint tape and compound, sand smooth, and prime before painting or tiling.

Think about its moisture resistance and acoustic benefits relative to cost. It’s a premium feature set for damp spaces, which can reduce long-term maintenance issues. Return terms vary by seller, so check the specific Fepy terms for returns and exchanges when purchasing.
