Key Advantages
-
High fire resistance: a reinforced plasterboard with a non-combustible classification under the Japanese standard NM-1498.
-
Exceptionally low water absorption: up to 5% total water absorption, in accordance with JIS A 6901 testing.
-
Improved mould protection: a dedicated treatment that helps limit mould growth in humid conditions.
-
Improved mechanical strength: a reinforced plasterboard designed for building systems with high durability requirements.
-
Long-term durability: a manufacturer’s test after ten years showed that the standard’s requirements for flexural strength and moisture content were still met.
-
Suitable for protected exterior systems: can be incorporated into external wall systems with appropriate waterproofing, cladding and ventilation.
-
Use in fire-resistant systems: suitable for incorporation into dedicated building systems in accordance with the manufacturer’s specifications.

The board is designed for use in building systems where combined resistance to fire and moisture is required, in accordance with the manufacturer’s specifications.
-
Interior walls and partitions: in systems requiring a reinforced plasterboard with improved water and mould resistance.
-
Protected external wall systems: as a fire lining layer within a system that includes a waterproofing membrane and suitable external cladding.
-
Timber buildings: for incorporation into dedicated fire-resistant systems in accordance with the system approvals and the design requirements.
-
Areas with varying humidity conditions: where a board with reduced water absorption is required, while maintaining appropriate protection against water penetration.
Installation Guidelines and Important Notes
Installation in external wall systems
In exterior systems, the board must be installed as part of a complete building system that includes a waterproofing layer, external cladding and a suitable ventilation solution. The board should not be regarded as a substitute for a waterproofing system.
Fire resistance
The board must be installed in accordance with the approved system specification, including the number of layers, the type of framing and the fixing means. The NM-1498 classification refers to the non-combustibility of the board material and does not in itself determine the fire-resistance duration of the wall.
Exposure to water
Despite the improved resistance to water absorption, the board must not be used where it is permanently exposed to water.
