Various techniques are employed in the design of steel structures to prevent or minimize thermal bridging, which refers to the transfer of heat through a material that is more conductive than the surrounding materials. One common method involves incorporating thermal breaks, which are insulating materials placed between the steel members to interrupt the flow of heat. These thermal breaks can be made of rubber, foam, or fiberglass, all of which possess low thermal conductivity.
Another approach involves the use of continuous insulation, where a layer of insulation is installed on either the exterior or interior of the steel structure to create a barrier against thermal bridging. This insulation helps maintain a consistent temperature within the building by reducing the transfer of heat through the steel members.
Furthermore, optimizing the geometry and detailing of the steel structure can minimize thermal bridging. For instance, thermal breaks can be strategically positioned at the connections between steel members, where heat transfer is most likely to occur. Additionally, the design may incorporate measures such as adding extra insulation around windows and doors, using thermal breaks in balconies or cantilevered structures, or increasing the thickness of steel members in areas prone to higher levels of thermal bridging.
During the design process, computer modeling and simulation techniques are often employed to analyze and predict the thermal performance of steel structures. This enables engineers to identify potential areas of thermal bridging and make the necessary adjustments to minimize its impact.
To summarize, steel structures are designed to prevent thermal bridging through the incorporation of thermal breaks, continuous insulation, optimized geometry and detailing, and the utilization of advanced modeling techniques. These strategies contribute to the creation of energy-efficient buildings with enhanced thermal performance.
