美国的热施工叠层屋面正在继续取得进展。首先高性能的玻纤毡用量不断增加。接着是规格有了改进,施工技术有了进展。沥青卷材制造者协会的目的在于为叠层屋面确立一种“系统”法。现正在制定的功能准则是用于整个屋面组合体的。与此相反,美国材料和试验学会的标准仅涉及叠层屋面的一部分,例如油毡或沥青。新的功能准则文件将不涉及材料、厂家及屋面系统如何铺设。它只根据抗拉强度、耐火性、耐风揭性以及其他的试验阐述叠层屋面系
The thermal construction of laminated roofs in the United States is continuing to make progress. First, the use of high-performance glass fiber mats continues to increase. Then there was an improvement in specifications and progress in construction technology. The purpose of the Asphalt Coil Manufacturers Association is to establish a “system” approach for laminated roofs. The functional criteria currently being developed are for the entire roof assembly. In contrast, the standards of the American Society of Materials and Testing only refer to a part of a laminated roof, such as linoleum or asphalt. The new functional guidelines document will not cover how materials, manufacturers, and roof systems are laid. It only describes laminated roof systems based on tensile strength, fire resistance, wind resistance and other tests.
