How to Install Typar House Wrap


A variety of manufacturers produce house wrap products designed to help insulate a newly constructed home or building from the extreme temperatures and precipitation of the outdoors. Typar HouseWrap is meant to be installed after the framing of the home is complete but before the windows and doors are installed. The material is attached directly to the boards that form the sides of the house. For best hold you must first locate the studs and ensure that you have the proper fasteners.

Things You'll Need

  • Stud finder
  • Pencil or chalk
  • Plastic-capped nails
  • Hammer or nail gun
  • Measuring tape
  • Construction tape
  • Utility knife
  • Locate all of the studs in the wall with a stud finder. Draw a line vertically down the entire wall to mark the location of the studs so that you can fasten the Typar HouseWrap securely.

  • Line up one end of the Typar HouseWrap roll with the starting corner of the home, with the printed side facing out. The bottom should extend 2 to 4 inches below the bottom of the wall. Stretch 12 inches of the HouseWrap around the corner so that you will overlap with the adjoining wall for best strength.

  • Hold the HouseWrap firmly in place against the wall. Move to the first stud marking. Starting at the bottom of the HouseWrap, install a plastic-capped nail into the stud with a hammer or nail gun.

  • Work your way up the stud, installing a nail every 32 inches up the stud until you have firmly secured the roll in place. Work your way down to the next stud and use the same procedure. Cover all holes for walls and doors; you will open those later.

  • Move around the entire building on the bottom level. When you need to start a new roll, overlap with the old roll by 6 inches. Continue until you have covered the bottom of the house.

  • Move up to the next row, overlapping the second row by 6 inches over the first. Use the same installation procedure as before until the entire house is covered.

  • Seal the seams between rolls of Typar HouseWrap with construction tape to prevent moisture from leaking through the seams.

  • Locate the windows and doors of the home. Cut a horizontal line through the HouseWrap with a sharp utility knife running the length of the top of the window.

  • Cut vertically downwards from the center of the horizontal cut, extending two-thirds of the way down the height of the window. When you reach that point, cur diagonally downwards to the bottom two corners of the window. The cut will resemble an upside-down "Y".

  • Push the flaps formed by the cut in through the window and secure them to the frame of the window with finishing nails or staples. Repeat for all windows and doors. This allows for fixture installation.

Tips & Warnings

  • It will make this project easier to have someone hold onto the wrap for you while you install.
