Thermally Broken Steel USA supplied the custom thermally broken steel wine cellar and a custom steel 90minute fire-rated entry door. Both assemblies were designed to look as though they came from the same frame collection but utilize completely different profiles due to the nature of the functionality required. The thermal break in our OS2 series steel frames keeps the wine cellar at the ideal temperature and the low iron glass makes for a perfect view of the owner's wine collection. Additionally, the custom fire rated steel entry door features the same handle and trim set as the wine cellar as well as a concealed floor mounted closer and fluted glass for privacy.
