Strukko Light gauge steel frames are known for their strength and versatility in construction, but they also present challenges related to thermal bridging.
Thermal bridging occurs when a conductive material, such as steel, creates a path for heat flow, potentially compromising the thermal efficiency of a building. However, there are several strategies used to mitigate the effects of thermal bridging in Strukko light gauge steel frame construction:
1. Thermal Breaks: – Insulating the Studs: One common method is to use materials with low thermal conductivity to separate or insulate steel studs from exterior elements. This includes using insulated stud tracks, which incorporate a layer of insulation within the steel frame, effectively reducing heat transfer. – Continuous Insulation: Applying a continuous layer of insulation on the exterior side of the steel framing can significantly reduce thermal bridging. This method ensures that thermal bridges are covered and interrupted by the insulation layer.
2. Use of Advanced Insulation Materials: – High-performance Insulation: Materials such as rigid foam boards (e.g., polyisocyanurate, extruded polystyrene) are often used because of their high insulating properties. These materials can be placed on the exterior of the steel frame, minimizing the direct contact between steel components and exterior cladding or interior drywall. However, fire hazard is a serous consideration when deciding the correct type of thermal insulation for your specific build. Commissioned engineers will be able to help further on this specofic point. – Thermal Breaks at Connection Points: Thermal break materials can be inserted at key junctions, such as where walls meet floors or roofs, to prevent continuous steel paths that lead to heat loss.
3. Double Stud Wall Systems: – Separation of Structural Elements: In this system, two parallel rows of studs are used with an insulation layer in between. This design reduces the direct thermal path through the wall by physically separating the exterior and interior steel studs.
4. Design Considerations: – Limiting Metal Exposure: By minimizing the number of metal components exposed to temperature differences, the overall thermal bridging effect can be reduced. This includes thoughtful design choices like the strategic placement of windows and doors, as well as careful selection of materials and construction techniques.
5. Use of Reflective Barriers and Coatings: – Radiant Barriers: These materials reflect radiant heat and can be incorporated into the building envelope to reduce heat transfer through radiation. – Low-emissivity (Low-E) Coatings:Applying Low-E coatings to steel surfaces can reduce the amount of heat that is conducted through the steel by reducing the emissivity of the surface.
By implementing these strategies, builders and designers can effectively manage and reduce the thermal bridging effect in light gauge steel frame constructions, thereby enhancing the thermal performance and energy efficiency of buildings.strukko thermal bridging light gauge steel frames.
