Armatherm™ Z Girt


Armatherm thermally broken cladding support connection solutions prevent excessive heat flow and potential condensation problems otherwise associated with thermal bridging. Moreover, wall assemblies using Armatherm attachments will meet the continuous insulation requirement of ASHRAE 90.1 and the effective R value requirements of the Canadian NECB energy code.

Modelling results show that using Armatherm Z girts results in several improvements in the thermal efficiency of wall designs, reducing heat flow:

  • The insulation efficiencies of the wall assemblies increase significantly. Some as high as 98%.
  • Higher, effective wall assembly R values are achieved using lower values of external insulation. For example, to obtain an R value of R-13 minimum to meet ASHRAE zone 1, steel girts require and external R 20; whereas Armatherm girts require only R 10.
  • Cladding wall assemblies can meet the R value requirements of ALL geographical zones for both ASHRAE 2013 and NECB 2011 energy codes using Armatherm Z girts.
  • Reduction in thickness and cost of insulation.
  • Reduces energy consumption.

Improve Wall Assembly Efficiency

How can we improve cladding attachment details and design wall assemblies that maximise insulation values so they reduce heat loss, reduce cost and meet energy codes?

Armatherm cladding attachments significantly improve wall assembly thermal performance. Armatherm Z Girt, clip and thermal break shims provide a combination of low thermal conductivity and high mechanical properties that transfer load and reducing heat loss.

Cladding Thermal Bridging Solutions

Cladding and panels are usually attached to the steel stud framing with a metallic Z girt within projects. They can result in thermal bridges, bypassing the exterior insulation and making it non continuous, as the designs are highly conductive. Thermal bridges, which can be referred to as cold bridges, heat bridges or thermal bypasses, are areas which have higher thermal conductivity than the surrounding materials. This creates a pathway for energy transfer. Shockingly, thermal bridges are often overlooked when calculating a wall’s true thermal efficiency. Using steel girts can reduce the R value of a wall by as much as 50%. This also causes potentially detrimental efficiency results to a construction project. The internal side of steel and aluminium attachments can be cooled by the unaccounted heat flow. This can cause major issues during the building’s lifespan, especially if the dewpoint of air in the wall cavity, where condensation can occur, is cooled. The condensation will result in damp patches, leading to dangerous mould problems and negatively impacting a resident or visitor’s health.

To improve the U value of cladding and wall panel assemblies, an Armatherm™ Z Girt system is strong enough to hold most cladding and insulation details. It eliminates the use of highly conductive metal girts and aluminium brackets, therefore creating up to 98% more efficient wall panel assemblies. Furthermore, architects and structural engineers must ensure they are up to speed with the latest innovations in thermal break technology, this will allow them to make efficient buildings consistently and protect the future of construction.
