About us

From your basement to your roof, from the front door to the back, Frost King products are there to save you money and save you energy. Frost King, simply the trusted name in home insulation. It all began nearly a century ago when Frost King introduced the nation’s first do-it-yourself weatherstripping kit. That simple kit, just 17 feet of felt carpet strips and some nails, managed to single handedly ignite America’s “Do-It-Yourself” revolution. Since that time, Frost King has expanded to help you save money and energy in just about every corner of your home. During the winter, Frost King products will keep the cold air out, insulate your pipes and protect your rooftops from freezing snow. In the summer, Frost King keeps gutters clean, protects your home from leaks, and cuts air conditioning costs.

Fixed a sliding glass door gap and stopped the draft.
5 Stars
Fixed a sliding glass door gap and stopped the draft.
We had a drafty seal on our sliding patio glass door because of an earthquake-caused misalignment.Fortunately, the glass did not break, but the panel alignment shifted enough so that It is not possible to adjust the doors far enough to thoroughly seal the gap, so we use this flexible compressible caulk saver to do so.In addition to being affordable ($2 on sale), the caulk saver is removable and reusable. We don't use ANY caulk in this application -- just to stuff and seal the small door gap.It takes less than a minute to insert the foam strip and it's compressible so that it will fit into the gap and expand enough to be an effective seal.We can quickly remove the strip when we want to open the door, and seal it back up in less than a minute.While this isn't a perfect and permanent fix, it's cheap, fast and much less expensive than installing a new door system.I've attached my image -- it's not necessary to leave such a large overhang, but we do so to make it easier to remove and replace the foam strip.
