United Gypsum Board – Fire Resistant Sheet (FR)

Product Name

United Gypsum Board – Fire Resistant Sheet (FR)

Dimensions & Physical Properties

• Length: 2440 mm
• Width: 1220 mm
• Thickness: 12 mm
• Weight (Approx.): 25–30 kg per sheet (depending on density and additives)

(Standard size suitable for drywall partitions and ceiling systems)

Material Composition

• Core made of high-density gypsum (calcium sulfate dihydrate)
• Reinforced with glass fibers and fire-resistant additives
• Covered with durable paper liners (often pink or red for identification)
• Special formulation improves structural integrity under high temperatures

Key Features

• High Fire Resistance: Provides fire rating typically from 30 minutes up to 2–4 hours depending on system design
• Non-Combustible Core: Gypsum releases chemically bound water when exposed to heat, slowing fire spread
• Enhanced Strength: Glass fiber reinforcement prevents early collapse during fire
• Thermal Insulation: Reduces heat transfer across walls and ceilings
• Acoustic Performance: Offers sound insulation properties
• Smooth Finish: Suitable for paint, wallpaper, and decorative finishes

Identification

• Typically pink or red face paper (industry standard for FR boards)
• Marked as FR / Fire Rated / Type X / Type F

Applications

• Fire-rated wall partitions
• Fire-rated suspended ceilings
• Shaft walls and service ducts
• Escape routes, corridors, and staircases
• Commercial, industrial, and high-rise buildings

Widely used where fire safety compliance is required.

Installation Compatibility

• Suitable for metal framing systems (GI channels)
• Can be used in multi-layer systems to achieve higher fire ratings
• Compatible with fire-rated jointing compounds and sealants

Advantages

• Provides critical time for evacuation during fire
• Helps meet building fire safety codes and standards
• Easy to install like standard gypsum boards
• Durable and dimensionally stable under heat

Limitations

• Fire rating depends on complete system (frame + layers + installation), not board alone
• Not waterproof (use MR/WR board in wet areas)
• Higher cost than standard gypsum boards
