Armatherm™ Z Girt Structural Thermal Break

Thermal bridging is recognized as a significant factor in building envelope heat loss. It has been determined that the total heat flow through typical wall assemblies is underestimated by as much as 70% due to thermal bridging, yet simply adding insulation to walls has been proven to not necessarily decrease the energy use of a building. Heat flow paths (thermal bridges) allow heat to by-pass the insulation, negating any benefit of installing more insulation in the wall.
Metal, cement and laminate wall claddings are supported by and attached to continuous girts or clips that penetrate the exterior insulation layer, creating thermal bridges. These fastening systems are normally made of highly conductive steel or aluminum, creating significant energy (heat) loss. It has been demonstrated that these thermal bridges in conventional steel stud wall assembly construction reduce insulation effectiveness (R value) by as much as 50%, resulting in wall assemblies and interface details that do not meet current energy code requirements for minimum U value.

Improve Wall Assembly Efficiency

How can we improve cladding attachment details and design wall assemblies that maximize insulation values so they reduce heat loss, reduce cost and meet energy codes?
Armatherm cladding attachments significantly improve wall assembly thermal performance. Armatherm FRR Z Girt, clip and thermal break shims provide a combination of low thermal
conductivity and high compressive strength transferring load and reducing heat loss. The material is made of a reinforced, thermoset resin that is fire resistant and exhibits very limited creep under load, making it the ideal material for use in structural and façade thermal break connections.
