Why Thermal Bridging Undermines Building Efficiency
In construction today we have to look for every possible opportunity to improve the efficiency of the building envelope. Sorting and prioritizing areas where we can improve is a great place to start.
A key challenge that is often encountered in building construction is thermal bridging, also known as cold bridging, which can undermine the efficiency of a building’s insulation and significantly increase energy consumption. Thermal bridging results in heat transfer across insulation, creating areas of increased heat loss and in some cases, condensation and damp issues.
How Steel Z Girts Create Energy Loss
Traditional steel Z girts, often used to support cladding and insulation, are notorious for their heat-conductive nature, creating thermal bridges that compromise and short circuit the overall energy efficiency of a building envelope. Studies have shown that these steel attachments can reduce energy efficiency by up to 50%, allowing a significant amount of energy to escape. It’s ironic that the steel z girt, acting as the insulation retainer, turns out to be a big part of the problem!
Why Armatherm Developed a Non-Conductive Z Girt
Recognizing the detrimental impact, Armatherm™ Thermal Bridging Solutions developed an ingenious product – the ArmaGirt™ Z Girt. Swapping traditional steel Z Girts for these high-performance alternatives can pave the way for remarkable energy savings and eliminate cold bridging.
How Armatherm Z Girts Prevent Thermal Bridging
These non-conductive Z Girts act as thermal breaks, effectively isolating the interior wall from the exterior, preventing heat loss. By utilizing the innovative properties of pultruded fiberglass (FRP), ArmaGirt™ Z Girt ensures a highly efficient system that maintains the desired U-value of a building’s insulation.
Meeting Energy Codes with Armatherm Z Girts
By replacing steel Z Girts with Armatherm’s innovative alternative, contractors can achieve remarkable energy savings, improve overall energy performance and comply with building energy code standards. Wall assemblies using ArmaGirt™ Z Girt meets the continuous insulation requirements of ASHRAE 90.1 and Canadian NECB energy code.
The Armatherm product range includes a Z Girt, clip and thermally broken shims that provide a combination of low conductivity and high mechanical properties that transfer loads and reduce energy loss.
Fast Installation and Size Options for Contractors
Armatherm’s innovative Z Girt products benefit from a simple installation process and secure cladding anchoring base. The cladding attachment systems significantly improve thermal performance. Armatherm’s FRP Z Girts install just like the steel girt, with self tapping screws, straight 9’ lengths go up fast, so no extra training is needed. Armatherm stocks 7 sizes ready to ship – 1.5”, 2”, 2.5”, 3” 3.5”, 4, and 6”.
It’s time to rethink traditional construction methods and embrace the future of energy efficient building envelopes. ArmaGirt™ Z Girt is in stock, in seven sizes – ready to ship directly to your site. Get in touch with us to arrange delivery today.
