Chicago Window Expert Nobody knows more about windows.
  • Window Consultant for Building Professionals

    Windows are a prominent feature of nearly every building. Sometimes they perform well, and sometimes not so well. Window consultants help architects, engineers, contractors and building owners make decisions about windows for new construction, window replacement or refurbishment. There are many choices to make. And even more decisions when things go wrong.

    As window consultants, we provide the benefit of our 37 years of experience in the window industry to these professionals. We provide them with critical information about windows.

    We can help you with these important choices…

    • Window design pressure: What is appropriate for the project?
    • Window frame material: Aluminum, wood, clad, vinyl or fiberglass?
    • Window, window wall or curtainwall: Which do I need?
    • Window frame performance: What CRF (Condensation Resistance Factor)is appropriate?

  • Sir: I consult you because Ic6p8 have a leak between the top of aluminum frame of window in my living room. The leak has been going on for years. Numerous personnel have work in it including an engineer and it still persist. This happens ever since I change this window and place new frames in a new configuration of the glass window. My apartment is on the 17th floor. It faces the northeast of the island and when heavy rains in this direction hit the glass, water leaks strictly at the border of the top frame The y have place sealant like sikaflex and the leak still prevails. Just like shutters were removed and the area where the frame and the building is, and seal it and everything fails. I I I am so frustrated. Can you help me?

Wallner lines at NiS inclusion
This nickel sulfide inclusion is quite unique - it has a typical spherical ball, at right, but then it has an unusual elongated impurity. We'll call that the tail. Curved lines in the mirror are called Wallner lines. They indicate the direction of crack propagation. Since the inclusion is at the center of the break, the Wallner lines emanate in many directions.
