An important element in CSR Gyprock Impact Damage Resistant Wall Systems is CSR Gyprock Impactchek, which is a purpose designed fibreglass bonded mesh reinforced plasterboard that exceeds the requirements of the Building Code of Australia (BCA) for soft body impact resistance. Impact damage resistance is not directly related to acoustic performance, acoustic requirements should be addressed as an additional issue where appropriate. Advantages Soft body impact resistance in excess of the BCA strength requirements. Can be used in fire rated systems. Can be used together with stard 13mm plasterboard. Can be used effectively in acoustic wall systems. Easy to install. Saves time money compared to other impact resistant wall systems. Uses stard plasterboard fasteners fixing methods. Easy to joint finish using 2 stard compounds methods. Damage that may occur is more easily repaired. Violet coloured face paper for easy identification. Gyprock Impactchek plasterboard has been primarily developed for use in areas that are required to be resistant to soft body impact in accordance with the Building Code of Australia Clause C1.8. Although the highest impact damage resistance is only required by the BCA in some Class 9 Building situations, the inherent impact resistance of Gyprock Impactchek plasterboard makes it ideal for all areas of high pedestrian traffic in all building types, it should be used wherever there is a risk of impact damage. These risk areas include corridors, foyers stair shafts in commercial buildings, shopping centres, cinemas, offices, sports stadiums, schools, hospitals nursing homes, walls in public transport structures such as railway stations or bus airport terminals. Gyprock Impactchek plasterboard can also be used in fire rated wall systems with a fire rating level () of up to 120/120/120 where higher impact damage resistance is also required. Gyprock Impactchek is also useful in acoustic wall systems given the product s high density.

3 Design Considerations SYSTEM PERFORMANCE. All wall configurations detailed in Table 2 have been laboratory tested to establish their structural performance characteristics. To produce this specified performance, field installation of these systems must comply with the stud spacings detailed all relevant installation detailing as specified in the CSR Gyprock Fire & Acoustic Design Guide, NºGYP500 or the CSR Gyprock Steel Frame Wall Systems Installation Guide, NºGYP544. The substitution of materials or a compromise in assembly may result in failure under critical conditions. IMPACT RESISTANT WALL SYSTEMS. An impact resistant wall system can be designed constructed from any wall system detailed in the CSR Gyprock Fire & Acoustic Design Guide, NºGYP500, by substituting Gyprock Impactchek plasterboard in lieu of the specified CSR Gyprock Plasterboard products as detailed in Table 1. The Gyprock Impactchek must be applied to the traffic side or sides of the wall in accordance with the BCA requirements, can be either the first or second layer in two layer systems. FIRE RESISTANCE LEVEL. The Fire Resistance Level () of a CSR fire rated wall system will not be detrimentally affected by the substitution of lining material as detailed in Table 1. SOUND TRANSMISSION CLASS. The Sound Transmission Class (STC) of a CSR wall system will not be detrimentally affected by the substitution of lining material as detailed in Table 1. Where 13mm Gyprock Impactchek is used in lieu of 13mm Gyprock Plasterboard CD, an improvement in the STC may be experienced.
