Fire Resistant Gypsum Board

A Fire resistant gypsum boards provides good fire protection in buildings due to the unique behaviour of the gypsum core when exposed to fire. When a fire resistant gypsum board protecting building elements that are exposed to fire, the chemically combined water is gradually released in the form of water vapor. This condition is caused in general use if the board or gypsum finish is continuously exposed to a temperature over 49°C.

FIREBLOC® Plasterboard

FIREBLOC® Plasterboards are manufactured with mineral additives such as glass fibresetcin the gypsum core to improve the core cohesion at high temperatures and reduce the shrinkage when exposed to heat. These boards are with Pink color Paper liners.

Specifications

* Size: 1830 mm X 1220 mm & * 2440 mm X 1220 mm
* Thickness: 12.5 mm & 15 mm

 

Application

* FIREBLOC® boards are recommended to meet the desired fire resistance in drywalls & false ceilings, beam & column encasement systems etc.
* Apart from fire resistance properties the Firebloc boards also help to achieve acoustic levels required, when installed as a system with different configuration of plasterboards.

What is a Knauf Fire Resistant Gypsum Board?

Knauf Fire Resistant Gypsum Boards are high-performance drywall panels with a gypsum core reinforced by glass fiber and mineral additives, designed to provide enhanced fire protection compared to standard boards

Where are Knauf Fire Resistant Gypsum Boards used?

They are ideal for:Drywall partitionsCeilingsWall liningsShaftwalls and are recommended wherever passive fire resistance in interior building systems is required

How do these boards achieve fire resistance?

The core composition includes glass fiber and special additives, allowing the board to maintain structural integrity and slow heat transfer during fire exposure. This results in fire resistance of up to 180 minutes for assemblies, depending on system build-up

What are the standard sizes and thicknesses?

Common sizes include:Thickness: 12.5 mm, 15 mm, 18 mmWidth: 1200 mmLength: 2400 mm, 3000 mm (other lengths may be available by request)Board weight (12.5 mm): ranges from approx. 10 to 10.8 kg/m²

What is the appearance or identification of these boards?

The front face is pink (indicating fire resistance)The back face is typically grey

What are the key standards and certifications?

EN 520 Type F (fire resistant gypsum board)ASTM C1396 Type X (for US/international compliance)Reaction to fire: A2-s1, d0 (non-combustible, minimal smoke development)Boards may also comply with additional local/national standards

What is the acoustic performance?

Knauf Fire Resistant Gypsum Boards, when used in complete Knauf partition or ceiling systems, contribute to enhanced acoustic insulation as well as fire safety

How are these boards installed?

Can be cut easily to size.Mounted on suitable frameworks (metal/wood), using Knauf screws and jointing compounds.Installations must follow Knauf system guidelines to achieve stated fire ratings

Are special finishes required?

Boards are suitable for direct decoration after jointing—can be painted, taped, or otherwise finished as needed

Do these boards provide any other benefits?

Fully recyclable and environmentally friendly.Good flexibility and easy handling.Suitable for high traffic areas due to increased rigidity

How long does the fire resistance last?

When properly installed as part of a tested system, assemblies can reach fire resistance ratings between 1 to 3 hours or more (60–180 minutes, sometimes up to 240 minutes), depending on wall or ceiling build-up

Can Knauf fire resistant gypsum boards be used alone for fire protection?

No; the declared fire resistance rating applies only to the complete certified wall or ceiling system (including framing, insulation, fixings, jointing, etc.), not just the board by itself
