Looking for system solution for single layer roof waterproofing
Publisher: Administrator Date：2019-11-04
The new "Code for Fire Protection of Building Design" was officially implemented on May 1st. The code has some new requirements for roofing fire prevention. For example, "the roof waterproofing layer should be made of non-combustible and flame-retardant materials. When using flammable waterproof material and laying it on flammable When it is difficult to burn the insulation material, the waterproof material or the flammable and non-combustible insulation material shall be made of non-combustible material as the protective layer."
In this case, how to meet the requirements of fire protection in the process and formulation of waterproof materials and meet the needs of engineering construction is a crucial issue. At the recent 2015 China Building Waterproof Association Single-layer Roofing Technology Branch Annual Meeting and the 9th Single-layer Roofing Technology Seminar, relevant experts said that single-layer roofing enterprises should thoroughly study single-layer waterproofing coil equipment, processes and formulas. Problems such as finding a system solution.
Zhu Dongqing, chairman of the China Building Waterproof Association, said that single-storey roofing has entered the current high-speed development period from the first year of development in 2011. However, there is still a big gap between the domestic and foreign single-layer roof development levels, which is reflected in production equipment, Production process and product quality. He pointed out that the "Code for Fire Protection of Building Design", which was officially implemented on May 1, has a relatively broad requirement for single-layer roofing. The single-layer waterproofing membrane can be flame retardant or non-flame retardant, but it has flame retardant. The functional roof waterproofing material will become a hot spot in market development and application in the future. Because of the flame retardant and waterproof materials, it will reduce the level of building structure and reduce the cost of system engineering, which will win the favor of developers and win the market. However, in order to improve the flame retardancy of single-layer waterproofing membranes, it is necessary to add more inorganic flame-retardant materials, which may affect the construction performance of the materials. It is necessary for enterprises to carefully study the process and formula to achieve the best results.
