Doors – What type of threshold weather-stripping goes here

If your leaking problem is from loose fitting window sashes or a poor fitting door, the simplest and cheapest method would be to purchase some self-adhesive foam weather stripping. This rolled product can be easily installed at the bottom of a window or around the outside edge of the door frame. Select the smallest size that will help seal the gaps, then just peel and stick. Too large and you may have difficulty closing the door etc.

Another good window treatment is the clear plastic window film like the 3M Indoor Window Insulator that mounts to the frame of the window. Use a hair dryer to "stretch" the film, thus sealing any air leaking in around the sides or through poorly glazed panes.

All these products are cheap and available at any hardware store or box store like Lowe's or Home Depot. Stay warm!

I have seen this type of weather stripping many times on sliding doors. There is a flange on the weather stripping that fits into the mill work. It is a bit difficult to remove, and even harder to replace. They sell the replacements at most box stores. It is important to remove the flange from a small dido (gap) in the frame. Putting the new one in is tedious and often frustrating, but can be done. It is truly a poor design. Take your time, use a little wood glue as lube and a way to keep it in place, or use a surface mounted replacement. I have had some success with self adhesive pillow type weather stripping. I feel your pain! lol.
