If you’re located in states like New York (NY), Michigan (MI), Illinois, or anywhere with harsh winters, our thermal break iron entry doors are a must-have. Inserted with an insulated barrier(low-conductivity material) between the inner and outer iron frames, it will help reduce the heat transfer and achieve high insulation performance. The thermal break option is available across our entire decorative iron front door collection, ideal for customers in colder climates who want luxury and comfort.
