What Usually Causes Drafty Windows?

Windows are essential to your home’s comfort. It will be harder to cool or heat rooms if your windows are drafty. When this happens, your HVAC system will exert more effort to reach your desired temperature, causing it to consume more electricity. Addressing drafty windows can help ensure your living space remains pleasant and keep your energy bills from rising. 

Drafty Windows

Here are some of the most common causes of drafty windows. 

What Typically Causes Drafty Windows?

Deteriorating Seals and Weatherstripping

It isn’t uncommon for windows to become drafty due to deteriorated seals and weatherstripping. Over time, these materials can wear down due to constant exposure to the elements. When the seals around your windows fail, outdoor air will enter and conditioned air will escape. 

Poor Installation

Improperly installed windows are more likely to develop leaks. Gaps and openings around windows will allow air to pass through easily. Quality craftsmanship is vital to your windows’ longevity, durability and energy efficiency. It’s among the many reasons to hire a reputable contractor for your window replacement project. 

Aging Materials

As windows age, their frames can warp or shrink, creating gaps that are not visible but are large enough to let drafts indoors. Similarly, the glass can become less effective at insulating your home, especially if it’s single-pane. Old windows can significantly impact your humble abode’s comfort and energy efficiency.
