Believe it or not, some people don't know about weather stripping. Well, it is a pliable foam or rubber used to seal any gaps that may be around your doors or even windows. It comes in different lengths and types, but will fit most household needs. It is not that expensive and will help with not only your heating bills, but your cooling bills. It will also help to keep pest's out.
The two basic types of weather stripping are either foam or rubber. The foam type has a adhesive backing. This makes it easy to use. The rubber type can be glued into place, but will fit well in a groove door or window. What ever type you use, it all does the same function.
