Avoid the typical issues you get with steel windows
With typical steel window and door packages you're forced to accept certain realities: designing around super thick structural sections, windows 'sweating', poor energy performance.
MHB has addressed each of these unfortunate issues and developed a solution for each resulting in windows and doors that look beautifully uniform, handles heat deftly, and keeps 99% of the wind and water from leaking in.
MHB thin-framed steel profile systems make use of the specific qualities of steel to create very slim yet strong steel profiles for the creation of highly stable windows.
An important feature of this profile system is the minimal amount of framing needed to achieve structural integrity. MHB extends the sightline of 1 3/4" across mullions and transoms for a universally thin and functional appearance.
A SL30-ISO profile with 1 1/4" width and 3" depth has a bending resistance that's almost identical to aluminum curtain wall profiles that are 2" wide and over 5" deep.
MHB profile's high strength allows large window panels to be installed. In many situations, fixed glazed panels can achieve at high of over 9 feet, depending on wind loads and glass specification.
Here is a selection of performance values for fixed glazed windows (SL30-ISO®) achieved with three types of glazing according to NFRC standards. Test results as low as shown below:

|Glazing Type||Low-E||Solar Glazing||Triple Glazing|

The SL30-ISO® steel window system is able to conceal a fully integrated water drainage system within the profiles thanks to the system’s superior sealing components. This results in a high level of wind and water tightness without any visible holes or rain caps.
