What should I use to seal a window frame? Both types will work, but one has proven its superiority with the test of time. Either acrylic latex/silicone caulk or window putty, also known as glazing putty, are commonly used for this purpose. Single-pane windows must be sealed into window frames to make them weatherproof. Can I use caulk instead of window glazing? This same siding movement is the reason that the siding comes with slotted nail holes. You are supposed to leave a gap at the end of the siding pieces to permit expansion and contraction.

Most vinyl siding, if installed correctly, will not require caulk at the sides of the windows and doors. Should I caulk around windows with vinyl siding? The truth is that in most cases it really doesn’t make a difference. One of the questions I’m asked by home owners shopping for Replacement Windows is should they be installed from the inside of the home or the outside.
