Our steel windows and doors through MHB offers the thinnest 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 thin 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.
The SL30-ISO® profile is one of MHB's most recent innovations. It is a slim-framed steel profile system that makes use of the specific qualities of steel to create a very slim yet strong and durable profile that is 99% wind and watertight and has insulation values few others are able to match.
The SL30® is specially designed for architects to enjoy the freedom of incorporate tall and very thin-framed glazed doors and walls into their creations.
The very thin 30 mm - 1 1/4 inch - sightline of the SL30® profile integrates perfectly into the design of a building, being almost invisible or enhancing the features of a building by playing with lines, colors and geometry.
The Classic-ISO® profile is one of MHB's most recent innovations, mimicking the well-known classic h-chair steel profiles and introducing an integrated thermal barrier.
It combines the specific qualities of steel with the latest innovations of MHB, resulting in a remarkably strong and slim profile.
Apart from being 99% wind and watertight, the Classic-ISO® profile encompasses insulation values that outrank the standards of modern façade systems.
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.
