耐火性是影响当今大多数建筑设计规范的一个重要因素。由于石膏是一种天然的耐火矿物，它已成为主要的建筑材料和耐火额定墙体组件组件。为了确保这些石膏板墙组件适用于指定的防火建筑设计，完整的墙组件进行防火测试，并相应地建立防火分类。有几种类型的防火墙组件，以适应各种应用和项目。不燃和可燃/承重和非承重是耐火墙组件的例子。区域隔离在相邻的联排别墅、公寓和商业建筑之间需要防火墙。整个系统，而不仅仅是个别的建筑材料，都需要测试以验证防火性能。影响防火性能的因素很多:石膏板的类型是关键。芯带玻璃纤维的石膏板比不带玻璃纤维的石膏板具有更好的防火性能。普通(标准)石膏板墙体组件的耐火性能随着石膏板密度的增加而提高。 Layering the number of gypsum board on each side of the assembly from one to two improves the fire resistance rating. Other system factors that impact the fire performance of wall assemblies include the type and installation of insulation, the type of stud and the arrangement of the studs within the wall. Well constructed and tested gypsum board wall assemblies offer a first line of defense against the spread of fire and lead to a more sustainable building.
