Product Description
9.5mm Moisture Resistant Gypsum Board 1220×2440mm (4×8 ft) – Lightweight Water-Resistant Plasterboard

The 9.5mm moisture resistant gypsum board is a lightweight interior finishing panel featuring a specially formulated water-repellent gypsum core and moisture-resistant facing paper. With standard dimensions of 1220×2440mm (4×8 ft) and a weight of approximately 7.5 kg/m², it complies with GB/T 9775-2008 and ASTM C1396 standards. This board is engineered for use in environments with moderate humidity, offering improved water absorption performance while reducing handling weight and installation time compared to conventional 12mm panels.

Key Performance Characteristics
  • Approximately 25% lighter than standard 12mm gypsum board, reducing labor fatigue and structural load
  • Enhanced moisture resistance with water absorption rate of 6.8%, suitable for areas with occasional humidity exposure
  • Good workability – scores and snaps cleanly using standard utility knives
  • Compatible with joint compounds, paints, wallpaper, and textured finishes
  • Lower transportation and handling costs due to reduced panel weight
Installation and Handling Guidelines
Important Technical Notes:

• Store panels flat on level supports in a dry warehouse (relative humidity ≤ 85%). Do not stack more than 8–10 panels high.
• Allow panels to acclimatize to site conditions for at least 24 hours before installation.
• Recommended installation temperature range: 5°C to 40°C. Avoid prolonged exposure to humidity above 90% without additional vapor barriers.
• Use a sharp utility knife or fine-tooth saw for cutting. Wear dust mask and eye protection to control gypsum dust.
• Ensure the supporting metal or timber frame is level and securely fixed according to structural requirements.
• Clean the surface only with a soft cloth and neutral detergent. Avoid abrasive cleaners or solvents.
• In high-humidity zones, combine with proper ventilation and consider additional waterproofing measures where necessary.
Typical Applications
  • Interior non-load-bearing partition walls in residential and commercial buildings
  • Suspended ceilings in offices, hotels, and retail spaces
  • Bathroom and kitchen walls with controlled moisture levels
  • Renovation projects requiring lightweight and easy-to-handle panels
  • Multi-family housing developments needing cost-effective moisture-resistant solutions
Project References
Selected Supply Records:

• Supplied 42,000 m² of 9.5mm moisture resistant gypsum board for a large residential development in Southeast Asia. The lightweight panels helped reduce installation time by approximately 18% compared to standard boards.

• Delivered 18,500 m² for a hotel renovation project. The improved moisture resistance performed reliably in bathroom and corridor partition walls.

• Provided 25,000 m² for a commercial office fit-out, where the reduced weight significantly lowered labor fatigue during ceiling installation.
Frequently Asked Questions
Is the 9.5mm moisture resistant gypsum board suitable for bathrooms?
A: It offers better moisture resistance than regular gypsum board and is suitable for areas with occasional humidity. For direct water splash zones, additional waterproofing membranes are recommended.
How does the weight compare to standard 12mm gypsum board?
A: The 9.5mm version weighs approximately 7.5 kg/m², which is about 25% lighter than typical 12mm boards, making handling and installation easier and faster.
What are the recommended storage conditions?
A: Store panels flat on level dunnage in a dry environment with relative humidity below 85%. Avoid direct sunlight or rain exposure.
Do you support custom sizes or OEM orders?
A: Yes. We can produce according to specific project requirements, including custom lengths and surface treatments, subject to minimum order quantities.
Are samples available?
A: Standard samples can be provided for evaluation. The buyer covers the courier shipping cost.
