Thermal bridging overview
The use of cast-in-place concrete elements, such as balconies or parapets, can create significant thermal bridges, reducing the wall U-value by up to 50% and compromising the building envelope. As modern building envelopes become more insulated and airtight, solutions like concrete balcony thermal breaks and effective thermal break concrete slab details are crucial to minimize heat loss and address issues at connection points.
Armatherm™ Cast-In SituKey Features
- 3” imperial or/ 75mm metric thick insulation body made from Armatherm™ 500-280 with a total R value of 5.7

- Standard ASTM bar sizes
- High-performance concrete compression modules
- Available with fire protection dependant on project requirements
The Solution
Enhancing the thermal performance of the building envelope and addressing thermal bridging are key priorities in modern construction. Increasing standards in local building codes, ASHRAE requirements, and sustainability programs like LEED emphasize this focus. Armatherm™ thermal breaks, including structural thermal break concrete solutions provide thermal break insulation for concrete slabs, effectively reducing thermal bridging.
The use of Armatherm™ CIS in concrete connections helps to:
- Prevent condensation and heat loss
- Improve the R-value
- Enhance indoor comfort
- Ensure compliance with building envelope standards
Advantages of the Cast-In Situ thermal break
