Question:

How does steel formwork affect the overall thermal performance of the structure?

Answer:

The overall thermal performance of a structure can be significantly affected by steel formwork. The thermal conductivity of steel is the main factor that influences this. Steel, with its high thermal conductivity, easily transfers heat from one side to the other. When constructing a building with steel formwork, it acts as a thermal bridge between the interior and exterior of the structure. This can lead to heat transfer across the steel formwork, resulting in increased heat loss or gain depending on the external temperature. In colder climates, steel formwork can contribute to higher heat loss, resulting in increased energy consumption for heating. Similarly, in warmer climates, steel formwork can allow heat to transfer into the building, leading to increased cooling requirements. To mitigate this thermal bridging effect, various measures can be taken. One approach is to use thermal breaks, which involve placing insulating materials between the steel formwork and the rest of the structure. These breaks help reduce the heat transfer through the steel, thereby improving the overall thermal performance. Another approach is to use alternative formwork materials with lower thermal conductivity, such as insulated concrete forms (ICFs) or wood. Considering the thermal performance of steel formwork during the design and construction phases is important to ensure energy efficiency and occupant comfort. By implementing proper insulation and thermal breaks, the negative impact of steel formwork on the overall thermal performance of the structure can be minimized.

Steel formwork does not significantly affect the overall thermal performance of a structure as steel is a good conductor of heat. However, it can indirectly impact thermal performance by providing a solid structure that helps in maintaining insulation materials in place, thereby improving the overall energy efficiency of the building.
