1 3/16" Wide Profiles

MHB offers the thinnest thermally broken profiles on the market. It's made by possible by applying smart engineering with steel's inherent strength and durable qualities. This means thin lines, large glass, and maximizing the amount of light you invite in on every project.

Uniquely, all available MHB ISO profiles are thermally broken as a standard for enhanced performance and maintains the same width across sightlines, mullions, and transoms for every window and door.

With MHB, you'll never settle form for function again.

Design Flexibilty

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.

In probably it's most popular project, the Brenne Architects of Berlin used MHB's Classic-ISO series to bring new life into the famous Bauhaus Institute campus.
