It's quick, and it's easy to install the Frost King Home Weather stripping tape. You can print out our easy to use instructions, or take a quick look at the handy guys video.


Should I clean the window or door before I install the Foam Tape?

A little warm water and soap should be enough to clean off any loose dust or oil from your window sill or door jam.
