Saint-Gobain Gyproc has announced the introduction of a new high impact resistance plasterboard walling system to its product portfolio in South Africa. Two versions of the Gypwall DuraLine system will be available locally, from July 2012.
GypWall DuraLine has a higher density core than the Gypwall Classic system, consisting of an aerated gypsum core with glass fibre and other proprietary additives. It is suitable for drylining internal spaces, offering a high-impact-resistant walling system for use where more durable structures are needed. It provides a lightweight, cost-effective, non-load bearing walling, ideal for high circulation areas such as corridors and stairwells in healthcare, education and commercial buildings.
Tested against respective South African, British and European standards, DuraLine has demonstrated its performance levels and durability. It achieved a duty rating of ‘severe’ in terms of the British standard BS 5234: part 2 test for structural strength; a 60-minute integrity and insulation fire rating according to SANS 10177 part 2; and sound resistance ratings of between 41db (without insulation) and 45db (with insulation) in acoustic tests done in accordance to BS EN ISO 140-3:1995.
GypWall DuraLine weighs just 14.75kg per square metre. It is a single layer walling system that can be built up to a height of 3.6m.and can be installed at a rate of 40 to 50 square metres a day. The product indicates a loading capacity of up to 120kgs of planned loadings and up to 30kgs of unplanned loadings.
Although new in South Africa, GypWall DuraLine has established itself as a preferred product for use in hospitals in India, having been installed in five hospitals to date and already specified for additional hospital projects due to be completed in 2012 and 2013.
It was specified, for example, as the plasterboard walling system for use in the recently completed 20 000m² Wockhardt Hospital in India. The entire project had to be completed in an eight- to twelve-month period and two floors, housing the ICU and twin-bed patient rooms, had to be finished within two months.
Gypwall DuraLine met all the specifications for the installation, including the time constraints of the project, the required strength of the board partitioning compared to a conventional brick wall, and longevity in terms of performance.
Saint-Gobain Gyproc recently commissioned a video recording of Gypwall DuraLine being put to the test. With school chairs and desks being physically thrown at the walls, they remained completely intact and undamaged – demonstrating the product’s real durability.
