Applications
ArmaGirt™ Z Girt
Armatherm’s thermal fractured cladding support connection solutions stop potential condensation issues as well as excessive heat flow that would otherwise be brought on by thermal bridging. Moreover, wall assemblies made with Armatherm attachments will satisfy the effective R value requirements of the Canadian NECB energy code as well as the continuous insulation requirement of ASHRAE 90.1.
The thermal efficiency of wall designs can be improved in a number of ways by utilising ArmaGirt™ Z girts, according to modelling results, which reduce heat flow:
- The wall assemblies’ insulation effectiveness dramatically improves, some reaching 98%.
- Lower values of external insulation allow for the achievement of higher, effective wall assembly R values. For instance, steel girts need an external R value of 20 to achieve a R value of R-13 minimum to comply with ASHRAE zone 1, whereas Armatherm girts only need R 10.
- With ArmaGirt™ Z girts, cladding wall assemblies can satisfy the R value criteria of ALL geographical zones for ASHRAE 2013 and NECB 2011 energy codes.
- Reduces insulating cost and thickness.
- Reduces the consumption of energy.

Wall Assembly Efficiency Improvement
How can we design wall components that maximise insulation values, enhance cladding attachment details, and minimise costs while still adhering to energy code requirements?
The thermal performance of wall assemblies is considerably enhanced by Armatherm cladding attachments. With a mix of high mechanical and low thermal conductivity, ArmaGirt™ Z girts, Clip, and Thermal Break Shims carry load while minimising heat loss.

When it comes to projects that include cladding and panels, these are more often than not attached to the steel stud framing with a metallic Z Girt. The metal designs are highly conductive, and they can bypass the exterior insulation making it non continuous, resulting in thermal bridges. A thermal bridge, also known as a cold bridge, heat bridge, or thermal bypass, is an area which has higher thermal conductivity than the surrounding materials, creating a pathway for energy transfer. Thermal bridges at the steel girts connection are often overlooked when calculating a wall assembly’s true working U-value. Steel z girts, designed to carry exterior insulation, are very conductive, and because they are attached to the steel stud-wall, are a thermal bridge themselves! The unaccounted heat flow can cool the internal side of steel and aluminum attachments below the dewpoint of air in the wall cavity where condensation can occur, which can cause major issues during the building’s lifespan. Condensation can cause damp patches which can result in dangerous mold problems which can negatively affect a resident or visitor’s health. Armatherm, pultruded fiberglass Z Girts, are non conductive and provide a secure surface to attach siding or cladding.
An ArmaGirt™ system is strong enough to hold most cladding and insulation details, and can improve the U value of cladding and wall panel assemblies by eliminating the use of a highly conductive metal girt and aluminum brackets creating wall assemblies that are up to 98% efficient. The addition of a fiberglass Z Girt, made from reinforced plastic, improves the U value of cladding and wall panel assemblies by eliminating the use of highly conductive metal girts and aluminum brackets, creating wall assemblies that are up to 98% efficient. It’s imperative that specifiers, architects and structural engineers are up to speed with the latest in thermal break technology to ensure their buildings are made as efficiently as possible to protect the future of construction. ArmaGirt™ come in 7 standard sizes, 1.5”, 2”, 2.5”, 3”, 3.5”, 4”, 6”, which will satisfy most insulation requirements. Our customers have been very satisfied with the quality and consistency of our Z Girts, and the quick quoting and fast delivery.
