Façades play a critical role in the durability and sustainability of buildings, where the design of façades is a critical aspect of building performance, that requires careful consideration of many factors such as sealing interfaces considering building movement and fire safety. Given the increasing prevalence of façade fires in the UK, façade fire safety has become critical and mandatory.
The consequences of inadequate sealing interfaces can be dire, leading to water leaks, lack of airtightness, energy inefficiency, poor indoor air quality, and even mould growth.
According to the UK Building Regulations Part A, the design of the building's structure should consider the combined effects of dead loads, imposed loads, wind loads, and ground movement. British Standard BS 6180:2011 provides guidelines for the design of barriers and loading that includes requirements for the structural performance of glazing systems.
British Standard BS 8213-4:2016 also provides guidelines for the installation of windows and doors, including methods for accommodating differential movement between the frame and surrounding structure. The flexibility of a façade and its ability to accommodate movement are critical to ensuring the safety and durability of a building's facade.
