When replacing an old window with a vinyl replacement window you will no longer need storm windows or separate screens. If there are screens or storms mounted outside the house, remove them first. This will allow you to thoroughly clean the opening and seal or paint any problem areas.
Use self-adhesive flexible flashing a minimum of 4″ wide, which has a self-adhering surface on one side. It should be approved for use on vinyl, wood and other substances such as house wrap. This flashing material must meet a minimum water resistance of 24 hours in accordance with ASTM-D779.
Sill flashing should already be applied before window installation and it should extend beyond the sides of the window nailing fin at least two inches.
Apply jamb flashing over the jamb-nailing fin, continuing over and beyond the sill flashing, two inches below. Apply the head flashing similarly, extending two inches past either side of the jamb flashing, to complete the window flashing detail.
Install batt insulation between the window and rough opening. It is very important that these openings are not over-stuffed because they can warp the frame. Do NOT use expanding foam. Doing so will void warranties.
To complete the installation and carefully seal against the weather, it is helpful to repair any damage to the outside of the house.
Fill any old storm window holes or screen holes with putty.
