How to Install Vinyl Windows

Vinyl windows are energy efficient and attractive and durable for any home. Because of their increasing popularity, vinyl windows are an excellent option for new construction. Their installation is straightforward since they are placed and attached to the frame with galvanized nails.

Supplies

• Tape measure


• Level


• Vinyl window


• Shims


• Hammer


• Galvanized nails


• Metal flashing

1. Measure the rough window opening and the window. The opening must be at least 1/2- inch wider than the frame of the window.
   
   


2. Check the rough opening to make sure it is level and square.
   
   


3. Weatherize the window opening by putting up construction plastic around the opening. Then apply the building wrap.
   
   


4. Lift the window into the rough opening. Attach the window to the sill with a single nail through the lower corner of the flange. 
   
   


5. Place any necessary shims on either side of the jamb between the window and the frame. They should be six-inches from the top and bottom, and run along the sides of the jambs. Glue the shims into place with silicone glue.
   
   


6. Check the window to make sure that it is operating correctly. Open and close it to check for any drag or difficulty in the operation. If problems are found, make any necessary readjustments to the placement. 
   
   


7. Check the window one more time to make sure it is level.
   
   


8. Nail the window into the frame once everything is working. Use the galvanized nails driven through nail slots in the flanges to secure the window in the frame.
   
   


9. Place flashing around the window and nail securely in place.
