Mark Meshulam, Chicago Window Expert

My name is Mark Meshulam. I am a building facade consultant with nearly 40 years of experience. I stumbled into the window/glass/facade industry in 1981 and have never looked back. It is an exciting field with ever-evolving technology. In this field, you literally never stop learning. As an added benefit, when you build buildings, you can bore friends and family by pointing out all the projects you ever worked on. For these reasons I encourage a career in construction.

But for some reason, the accumulated wisdom of the construction industry remains largely undocumented. Trades knowledge is one of the last bastions of the oral tradition, handed down from limping old-timer to buffed & tattooed newbie. Many of us make up our own construction terms (“sleevo bar”) and theories (“condensation is caused by cold air hitting warm air’) as we go along. Window and curtainwall design and testing are rarely taught in school. We just learn it as we go. Things could be better on the educational front.

So here is my small effort at bringing years of hands-on experience to those of you who, like me, are fascinated with building…

No matter where you are, Chicago Window Expert can help you

  1. I have a client who is insisting on using butt joints at every horizontal and vertical in glazed-in 1/8″ aluminum brake metal with legs and no back-up angles, instead of running the brake thru and using a splice joint. They said they had to zone the metal from the curtainwall. I though that was only necessary in Unitized systems, and is not a proper application for stick built system. To me, less butt-joints equals less leaks. Do you have any articles relating to this?

    Thanks,
