12 防火墙系统 - 防火等级(FRL) 当使用额外的防火衬里搭建时,Weathertex覆层可以达到60/60/60和90/90/90的防火等级。Weathertex可以方便地安装一系列由相关系统制 造商如CSR Gyprock和Boral详细列出的防火墙系统上。 您应当征询系统制造商的建议,为您的项目寻求合适的系统。 所有墙壁必须适用于所加载荷。对于承重墙和承受风压的墙壁,墙壁应按照澳大利亚标准或施工指南进行设计。设计人员应考虑由碳化引 起的轴向承载力下降(ACR)和因热量而引起的钢铁强度的降低。可以从有关FRL系统制造商寻求关于结构设计的指导。 本安装指南中的标准安装要求适用于Weathertex外部覆层部件的安装。必须根据框架和Weathertex之间使用的所有包装材料的厚度来增加紧 固件长度。 Note: Timber studs at maximum 600mm centres Direct Fix - 60/60/60* *ACR Group 1 Direct Fix - 60/60/60 and 90/90/90* *ACR Group 3 External Wall Side Weathertex 9.5mm Cladding direct fix Vapour Permeable Membrane 1 layer of 16mm Gyprock Fyrchek MR Plasterboard Internal Wall Side 1 layer of 16mm Gyprock Fyrchek Plasterboard Approximate* Thermal Rating (R-value) R(winter) = 2.5 and R(summer) = 2.3 *using 75 Soundscreen TM 2.0 infill Approximate* Acoustic Value (Rw) Rw = 45 *using 75 Soundscreen TM 2.0 infill External Wall Side Weathertex 9.5mm Cladding on Weathertex cavity battens Vapour Permeable Membrane 1 layer of 16mm Gyprock Fyrchek MR Plasterboard Internal Wall Side 1 layer of 6mm CSR CominSeal TM Wallboard 1 layer of 16mm Gyprock Fyrchek Plasterboard Approximate* Thermal Rating (R-value) R(winter) = 2.5 and R(summer) = 2.3 *using 75 Soundscreen TM 2.0 Approximate* Acoustic Value (Rw) Rw = 50 *using 75 Soundscreen TM 2.0 Cavity Fix - 60/60/60 Cavity Fix - 90/90/90 (from outside only) External Wall Side Weathertex 9.5mm Cladding on cavity battens Vapour Permeable Membrane 1 layer of 16mm Gyprock Fyrchek MR Plasterboard Internal Wall Side 1 layer of 16mm Gyprock Fyrchek Plasterboard Approximate* Thermal Rating (R-value) R(winter) = 3.0 and R(summer) = 2.8 *using 75 Soundscreen TM 2.0 Approximate* Acoustic Value (Rw) Rw = 42 *using 75 Soundscreen TM 2.0 External Wall Side Weathertex 9.5mm Cladding on cavity battens Vapour Permeable Membrane 2 layers of 13mm Gyprock Fyrchek MR Plasterboard Internal Wall Side 1 layer of 10mm Gyprock Plasterboard CD Approximate* Thermal Rating (R-value) R(winter) = 2.9 and R(summer) = 2.7 *using 75 Soundscreen TM 2.0 Approximate* Acoustic Value (Rw) Rw = 42 *using 75 Soundscreen TM 2.0 Typical FRL Systems 注意:本指南中的木框架和钢框架FRL系统代表着CSR Gyprok所提供的典型系统。应用必须符合系统制造商的安装要求和说明。
