time that you’ll have much of an issue with the installation is if there are
supporting beams or braces in the way. You will want to consult with the
builder and an architect when installing expansive windows because you have to
be sure that your windows will not lead to a weakening of the building
structure or integrity.
One consideration to point out is that when using aluminum windows, you need some type of buffer between the two metals. This is to prevent something known as galvanic action when aluminum and steel are in direct contact.
The key is to separate the aluminum frame from any structural steel elements to avoid galvanic action. This is done by using neoprene shims that are typically installed between the aluminum window frame and the structural opening. This creates a 1/4″ to 1/2″ space between the two different metals.

Install the windows where there is no support beam present.
If there’s an x-bracing at the location, do not place the window here. Metal building companies can move the x-brace if you let them know that you want to place a window in this location. Otherwise, you will have to choose another location for your window.
Standard windows are often preferred because they can be installed anywhere, while most metal building-specific windows must be placed on the sheathing, which is in place every 12 inches.
The metal building supplier or a third-party supplier should be able to sell you the hardware you need to install the window properly. You can source most items from the builder, including: bolts, clips and red iron angles.
Outside panels may need to be unscrewed to make sure that the J-mold will properly fit.
When putting the girts on the sides of your building, you can often put the windows in and simply slide the metal behind the molding. You’ll want to make sure the window is a snug fit and that it’s aligned properly.
You really can’t use too much caulk when placing a window. The caulk will block any potential leaks from occurring and you should spend additional time caulking the top of the window. Caulking the top is important because the majority of leaks that take place tend to happen from the top of the window.
If you plan
on having large, expansive windows, you should get in touch with your builder
prior to the manufacturing process. While metal buildings are durable, they
still rely heavily on loads and may have structural issues if expansive windows
with the manufacturer allows the design team to consider all of these load
issues and make adjustments to the design accordingly.
