Armatherm™ Cast-In Situ

Armatherm™ CIS is used in cast-in-place concrete slab and wall connections—such as balconies, parapets, and structural penetrations—to reduce heat loss, prevent condensation, and improve building envelope performance.

Armatherm™ Cast-In-Situ (CIS) Structural Thermal Break is designed to reduce thermal bridging in cast-in-place concrete elements such as balconies, parapets, and concrete slab connections. As modern building envelopes become more insulated and airtight, untreated concrete penetrations can significantly reduce overall wall performance and contribute to heat loss and condensation. Armatherm™ CIS integrates structural load transfer with thermal insulation by combining a high-performance insulation body, stainless steel reinforcement, and concrete compression modules. The system is engineered to improve thermal performance while maintaining structural integrity and supporting compliance with modern building codes and sustainability standards.

Features and benefits:

• Thermal Bridge Reduction – Effectively minimizes heat transfer at concrete-to-concrete connections.
• High Thermal Performance – 3” (75 mm) insulation body provides a total R-value of 5.7.
• Structural Load Transfer – Uses high-performance concrete compression modules for reliable load-bearing capacity.
• Stainless Steel Reinforcement – American 2304 Grade 75 stainless steel rebars offer strength and corrosion resistance.
• Standard Bar Sizes – Compatible with ASTM bar sizes for ease of design and installation.
• Rigid Insulation Body – Allows secure nailing to formwork and easy cutting on site.
• Installation Efficiency – Designed for straightforward handling, transport, and step-by-step installation.
• Project Flexibility – Available in imperial and metric sizes, with optional fire protection depending on project requirements.
