How to Install Windows in a Pole Barn. Windows also provide less of a shed or barn feeling to your construction, and expands the potential uses of the structure into an office or studio work space. Windows also allow you to let fresh air into your work space, without allowing in untold numbers of insects. Windows can be a great addition to any pole barn structure. Read on to learn how to install windows in a pole barn.
Place vertical support boards on both sides of the window opening. The hole should be approximately 1/2 to 1 inch larger all the way around than your window. Nail these boards to the horizontal supports for your barn walls. They should present a smooth face on the outside of your barn wall.
Place the moisture barrier around the entire opening of the window.
Add shims to the bottom of the window opening. Use your carpenter's level to level the shims. Pre-drill small holes in the shims so you do not crack them when you nail the shims into place. Nail the shims to the bottom window support.
Center the window into the opening and partially drive two nails into the flange on either side of the window frame to hold the window in place.
Level the window using the carpenter's level. Add two additional nails to the flange to ensure that the window is held level and in place. Do not add more than four nails to the outside of the window. As your building settles, the window will need to be able to somewhat float within the window opening.
Go inside your pole barn, and shim the inside edge of the window. This will help ensure the window stays level through adding the siding and trim to your barn.
Cut off the ends of the shims so they are flush with the inside and outside wall. You can use a hand saw or skill saw, whichever you have available.
