Our steel windows and doors through MHB offer the slimmest thermally broken profiles on the market. It's made by possible by applying smart engineering with steel's inherent strength to achieve similar widths across sightlines, mullions, and transoms for every window and door. Altogether, this means slim lines, large glazing, and maximizing your natural light in every project.
Uniquely, all available MHB ISO profiles are thermally broken, producing U-Values and energy performance ratings that rivals are hard pressed to match.
MHB’s patented profiles can be adjusted to fit different design styles without sacrificing performance, longevity, or strength. Whether your project calls for a traditional look of yesteryear or you’re pushing the boundaries with ultra-modernism, we can help you present a unified look across your entire project through fixed panels, radiuses, tilt-turns, multi-sliding doors, and more.
MHB Steel Windows and Doors are an ideal choice for restoration projects seeking landmark status. In possibly its most popular project, the Brenne Architects of Berlin utilized MHB's Classic-ISO series to bring new life into the famous Bauahus Institute campus. MHB was not only able to completely replicate the existing profiles, they enhanced the performance across the board through thermal breaks and smart drainage techniques.
Patented thermal break technology used in all of our ISO systems enhance your performance and saving on energy costs.
Invisible Drainage Caps keep water from passing through to your valuables and smart engineering keeps wind from passing through.
Rigorously measured and tested by ATI, MHB steel windows and doors are NFRC tested with specific forms available per project.
Order doors up to 12 feet tall and up to 48 inches wide thanks to the unique strength that steel can hold at half the structural footprint aluminum requires.
Choose from stock options or have your hardware custom created for your project by our engineers, ensuring that it's perfectly made for your products.
Steel's inherent strength can maintain structural integrity across transoms and mullions allowing for partitions to be made at the architects descretion.
