A draft of any kind whether from a door, window or anywhere else is a sure sign of energy loss. If you are noticing drafts anywhere in your facility, it’s probably a good time to audit how well window and door seals are holding up throughout the building.
Weatherstripping and sealing are used to protect your facility from outdoor elements that can impact indoor air quality. These seals also work to prevent the costly leakage of heated indoor air. Weatherstripping is typically used around moving building components like windows and doors. Over time, window and door seals can break down from aging, day-to-day wear and tear and weather. Once a seal is compromised, the breakdown of these materials will allow air to escape, which will eventually show up in your energy bill. According to This Old House, a 1/8-inch gap around your door could be equivalent to drilling a 5 1/2-inch diameter hole in an outside wall.
There are many choices for weatherstripping and sealing, so a little research can pay off in time, effort and money. For example, how do you know what material you need? How long should the replacement stripping be expected to last? The different types of weatherstripping are meant for different applications. Replacing your weatherstripping can be a pretty straightforward process, and if you’re strategic about it, you might be able to do it economically as well.
So how do you choose the right weatherstripping? Here’s a look at some of the more common weatherstripping and threshold types.
