Details on Installing Tyvek Window Wrap on a House


Tyvek window wrap is commonly installed on houses during the building process. It is applied over the exterior wall sheathing before the siding is installed. It comes in rolls and is a weather resistant barrier that helps prevent air leaks. Tyvek is a synthetic material that is very difficult to tear, but can be cut with scissors very easily. Installing Tyvek window wrap on a house is a job you can handle with the proper instructions and a little bit of patience.

Things You'll Need

  • Staple gun
  • Staples
  • Tyvek tape
  • Scissors
  • Roll the Tyvek wrap horizontally over one exterior wall surface, beginning at any bottom corner. Insert a staple every 16 inches on each vertical stud. Drive four or five equally spaced staples along the first stud to firmly secure the beginning of the wrap to the house. Continue rolling across the house making sure the bottom edge of the wrap is flush with the bottom of the wall.

  • Staple at every stud along the first side of the house to properly secure the wrap to the house. Roll directly over windows and doors. Continue around the house, wrapping the Tyvek around the first corner and continuing to apply the in the same manner as with the first side of the house. Insert staples into each stud until the entire bottom portion of the house is completely covered.

  • Cut the Tyvek window wrap with scissors when you reach the original starting point, and overlap it six inches. Start the second row just above the first. Overlap the two layers by six inches and install the second layer the same way as the first.

  • Tape the two layers together with Tyvek tape to secure them in place. Run the tape around the entire house to connect the top and bottom layers. Repeat the process, adding additional layers up the house until the entire exterior is covered.

  • Remove the wrap that is over doors, windows, vents, molding and other elements that should not be covered. Do this by cutting them out with scissors. Apply additional tape around the edges of the wrap if needed.
