1 3/16" Wide Profiles, 9' High Glazing

MHB takes advantage of steel's natural strength and durability to create profiles at 3 times the bending resistance of aluminum at half the size. This is especially unique when you consider that MHB's thin profiles are applied to not only the sightlines and mullions but to structural muntins. Through MHB, having staggered set steel windows is a thing of the past.

Chosen by World Class Architects

When the Brenne Architects in Berlin were tasked to reinvigorate the Bauhaus Institute in Dessau, they wanted an ultra-slim steel window that would keep out water, wind, and ensure great thermal performance while maintaining all the historical functionality of the original design. The only product capable of achieving that came from MHB.

Water and Wind Tight

MHB's steel systems are able to conceal a fully integrated water drainage system in the profiles thanks to their superior sealing components. This results in a high level of window and water tightness without any visible holes or rain caps.
