In addition to providing hurricane protection, impact doors and windows also help to reduce heating and cooling costs due to their insulating qualities. But the insulating qualities of impact windows and doors could cause too much moisture in your home. Here's what you need to know. 

House Will Be Sealed Tight 

Impact windows and doors are designed and built to withstand forceful impact from objects being hurled through the air during severe weather events such as tornadoes and hurricanes. Due to the rigidness of the windows and doors and the sturdy framing requirements for them, you'll feel very few (if any) drafts because there won't be many cracks to contend with around windows and doors. 

Moisture Won't Escape 

Water vapor (humidity) can be found in air, particularly in the southern U.S region that regularly has high levels of humidity. Since your home will be draft-free, your home will also retain the moisture that may have escaped through cracks around your old windows and doors. The reason for this is because water vapor will not escape the home unless vents in the bathroom(s) and kitchen are used regularly. 

Condensation Could Form On the Glass 

When your home is humid and there's a significant temperature difference between inside and outside, condensation will form on your new windows and doors. The formation of condensation can happen to any windows and doors, but it can be more extreme in homes with new impact doors and windows due to the tight seal that is created during the installation process. 

Ways to Reduce Moisture & Condensation 

Here are several ways you can reduce the moisture in your home and, therefore, the amount of condensation that forms on the glass throughout your home.

  • run a dehumidifier 
  • open a window or two to air out your house
  • install an automatic exhaust fan that activates at a preset humidity level

Of course, you can choose more than one option for results that will work best for you and your family. 

Troubleshoot Possible Water Leaks 

If you try the above methods and still have condensation on your windows and doors, you may have a hidden plumbing leak somewhere in your home, or your concrete foundation may be too porous and this is allowing moisture from ground water to enter your home. 

If you think there may be a water leak somewhere, hire a home inspection service or a plumbing contractor to use an infrared camera leak detector to locate areas of excessive moisture in your home.
