Exceptional Steel Windows & Doors

When you and your client's imagination and designs are to be executed without compromise: there is JANSEN High Performance Steel Windows.

We expand the Jansen performance with heating glass.

At IQRG, we have developed and mastered the use of electric heating glass, which eliminates ice and snow melt on glass roof lights, provides perfect indoor thermal comfort in the most challenging winter conditions, and eliminates indoor condensation on interior glass surfaces. Our fifth-generation electric heated glass allows for bold and daring use of glass and designs while integrating the glass interior and exterior into the smart building control system, providing sublime comfort and energy savings.
