The “Metal Movement” and “Thermally Broken.”. Why you want your metal windows to be BROKEN. Thermally broken metal windows provide several benefits over non-thermally broken systems. We are often asked about specific performance benefits. The basic performance premise is: Improved overall thermal performance over traditional non-thermally broken systems. Improved NFRC U-Values over non-thermally broken systems. The lower the u-value, the better the performance. Improved NFRC Condensation resistance factors (interior sweating/ice build-up). Narrow profiles equal or similar to traditional non-thermally broken. Easier Code Compliance than non-thermally broken systems. Sounds like a no-brainer, right? So how does it work?

As code compliance was being re-worked for several elements of the building envelope, the Title 24 consultant pointed out that the low thermal performance value of the aluminum windows meant the rest of the envelope now had to be boosted to compensate. The additional …
