Did you know there is a way to reduce point thermal bridges in a rainscreen assembly? A thermal spacer is a building component designed to reduce heat transfer between two surfaces.
In building construction, thermal spacers are commonly used between exterior cladding systems and the building envelope to minimize thermal bridging, which can cause energy loss and reduce building efficiency.
The material selected for a thermal spacer must have low thermal conductivity, high strength, and long-term durability. Common materials include thermally broken metal, fiberglass, and high-density plastic.
The size, shape, and thickness of the thermal spacer must be designed to meet the specific requirements of the cladding system and building envelope. Proper thickness is critical to preventing thermal bridging and minimizing energy loss.
Thermal spacers must be compatible with surrounding building components. Compatibility with the cladding system, insulation, and other envelope materials is essential to ensure the assembly performs as intended.
Improper material coordination can compromise thermal performance and negate the benefits of the thermal spacer system.
Design TOgether with your product manufacturers and façade consultants to identify strategies for reducing point thermal bridges using thermal spacers. Proper coordination ensures the spacer system improves energy performance without disrupting structural or envelope continuity.
In summary, thermal spacers help reduce heat transfer at connection points and support higher-performing rainscreen assemblies.
