Thermal bridging overview
Cast-in-place concrete components such as balconies and parapets can often create significant thermal bridges. These can reduce the wall U-value by as much as 50% and weakening the overall performance of the building envelope. As modern construction focuses on highly insulated and airtight envelopes, the need for balcony thermal breaks and well-designed concrete slab thermal break materials has become critical to limit heat loss at these 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
Improving thermal performance and addressing bridging issues are essential in today’s building practices. Stricter building codes, ASHRAE guidelines and green building standards such as LEED all emphasize the importance of effective envelope design. Armatherm™ thermal breaks, including structural thermal break systems for concrete, provide insulation within concrete slabs to significantly reduce bridging effects.
Using Armatherm™ CIS in Concrete Connections Can:
- Reduce heat loss and limit the risk of condensation
- Improve overall R-value performance
- Enhance comfort indoors
- Help meet building envelope requirements and energy codes
