【Case of Fire Stopping Between Floors】Chuangzhi Cloud City Project

Fireproof interlayer sealing of curtain walls

Project Background

        After the construction of the glass curtain wall, there is often a certain gap between the curtain wall and the floor slab of the main building structure. If this gap is not properly fire-sealed, it will become a major channel for the spread of fire or toxic fumes along the floors.

         The fire blocking between the layers of the building curtain wall, a seemingly insignificant but extremely critical link, is like an "invisible guard" for building safety. This narrow space can actually add 9 square meters of open space for gases, smoke, and flames to rise from the lower floor to the upper floor. Countless fire cases warn us that almost all international building codes have fully recognized the importance of fire blocking between the layers of the building curtain wall to the overall building safety design. It is not only related to the integrity of the building structure, but also directly related to the safety of people's lives and property losses.

         The Chuangzhi Cloud City project is located in Shenzhen, one of the core cities in the Greater Bay Area, and in Nanshan District, the core area of technological innovation with the highest GDP. A 1.36 million square meter smart city for emerging industries stands tall on the core innovation highland of the Bay Area. 

         In the fireproof sealing between the curtain wall layers of the Chuangzhi Cloud City project, Yuanyang Weili's curtain wall fireproof boards stood out. These boards are part of Oceanwide Willy's product line that focuses on fire resistance. Raw materials such as alumina, mica, and kaolin, which have excellent fireproof capabilities, are added to the raw materials, enhancing the fire resistance of the boards from the source. In terms of production technology, emphasis is placed on reducing the density of the boards and improving the molecular structure of the internal space of the boards. This measure has effectively reduced the thermal conductivity and significantly improved the fire resistance of the building. Case details
