The Gutmann S57ED Entrance System is a thermally insulated storefront door engineered for high-performance in entrance and storefront applications. Designed to endure moderate to heavy traffic, this robust system delivers exceptional thermal insulation, technical reliability, and adherence to North American ADA requirements, making it a premium choice for commercial building entrances.
Why Thermally Broken Storefront Doors Matter
Thermally broken storefront doors integrate a thermal barrier—often a polyamide strip or resin-based insulator—between the interior and exterior aluminum profiles. This innovation significantly reduces heat transfer, improves indoor comfort, and helps buildings meet ambitious energy codes and sustainability goals.
