BNBM
Gypsum board
Every element of construction within each compartment and every compartment wall or compartment floor should have an FRP of not less than that specified in Table 2 below.
Product Feature
Besides the excellent features of standard “Dragon Brand” gypsum board, fire-resistant series has the following function, High fire-resistant performance: the fire-resistant fiber glass and special additives, with the stability when fire reaches 45 minutes, which is well beyond the requirement of national standard, guarantees the excellent fire-resistant performance.
Notes:
-
Different use class should be separated in accordance with paragraph 8.
-
Special hazards should be separated in accordance with paragraph
-
For any use not covered by Table 2, the fire resistance period required will be determined by the Building Authority having regard to the fire load, hazard level, fire service installations and other relevant features of the building.

PARTITION DUTY STRENGTH AND ROBUSTNESS
BNBM Partitioning System provides strength and robustness. These duty ratings have been calculated in accordance with BS 5234: Part 1 & 2: 1992. The rating is a measure of the ability of the wall to meet therequirements of strength and robustness test. BNBM Partitions are characterized by high acoustic performance, low overall width and high fire resistance.

As an aid to specification, the figures below are guidelines for duty-strength/ robustness rating, and minimum sound reduction values for partitions separating various room types. The wall duty-strength and robustness-rating are grouped as follows:
Suggested minimum sound insulation values of partitions:
Suggested minimum sound insulation performance levels for privacy in some occupational conditions are given in table below. The values given are based on laboratory measurements.
Slim fire resistant and acoustic rated partition for all sorts of internal environments
In congested urban developments, high population is confined to small expensive space.This explains why high rise buildings are everywhere. This phenomenon creates problems in terms of fire risk and acoustic isolation between adjacent rooms, and the need to maximize living / working space for each individual is of paramount importance.
BNBM plasterboard partition systems offer many benefits over conventional masonry wall. Whether it is new construction or refurbishment, BNBM plasterboard partition systems offer greater flexibility in construction and relocation. Unlike conventional masonry wall, they are faster to construct and hence reduce delay to other trades. Because it weighs less than twenty percent of conventional masonry wall, the system reduces the building dead load. The system is also slimmer and the reduced thickness allows for more rentable space, which in turn increases the rental income potential.
