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 Situ
Key Features

  • 3” imperial  or/ 75mm metric thick insulation body made from Armatherm™ 500-280 with a total R value of 5.7
  • American 2304 Grade 75 stainless steel rebars for maximum structural performance and corrosion protection
  • 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

  • Effectively reduces thermal bridging and its impact in cast-in-place concrete walls and slabs
  • Simple range, making design and installation straightforward
  • Durable construction for easy transport and on-site handling
  • Rigid structural insulation body allows for secure nailing to formwork and cutting on-site
  • Quick installation with a step-by-step process
  • Fully adaptable to meet specific project needs
  • Designed for the construction market, available in both imperial and metric sizes, suitable for concrete-to-concrete thermal break applications
