Dealing with Drafty Windows?
How Air Infiltration Can Skyrocket Your Energy Bills—and What You Can Do About It
If you’ve noticed cold drafts near your windows or your energy bills climbing without a clear cause, you’re not alone. For many homeowners, air infiltration is a hidden but serious problem. In fact, drafty windows are responsible for up to 20% of a home’s heat loss.
Thankfully, there are effective solutions that go far beyond temporary fixes.
What Is Air Infiltration?
Simply put, air infiltration refers to the unintentional flow of outdoor air into your home through cracks, gaps, and poorly sealed windows. This means your home becomes drafty and harder to keep warm in winter or cool in summer.
As a result, your HVAC system runs longer and works harder, driving up your energy bills and creating inconsistent indoor temperatures.
How Does Air Infiltration Happen?
Drafts typically enter your home through several parts of a window, such as:
The sash
The meeting rail
The sash perimeter
The sill
Over time, these components break down. Additionally, poor window design or low-quality installation makes the problem worse from day one.
Why Drafty Windows Are a Bigger Problem Than You Think
At first glance, a small draft may seem harmless. However, these seemingly minor air leaks can lead to significant energy loss over time. Moreover, relying on quick fixes like caulk or weather-stripping only offers temporary relief.
In contrast, long-term protection requires a more permanent solution.
The Best Solution: Replace Drafty Windows with Energy-Efficient Ones
If your windows are more than 15 to 20 years old—or if you’re already seeing signs of air leakage—it’s time to consider energy-efficient replacement windows. Unlike temporary fixes, these modern windows are designed specifically to block air infiltration at its source.
At Coastal Windows & Exteriors, we provide:
Industry-leading air sealing technology
Windows that target and eliminate air leakage hot spots
Performance that exceeds national airtightness standards
How Do Our Windows Compare?
To illustrate, let’s take a closer look at the numbers:
Coastal windows allow only 0.01 CFM (cubic feet per minute) of air leakage—about the same as less than 1 soda can per window per minute.
Meanwhile, popular brands like Pella and Andersen allow 0.12 to 0.30 CFM—equal to 24 soda cans of air loss.
In other words, 23 of our windows leak the same amount of air as just one competitor window.
Therefore, choosing Coastal means significantly better insulation, lower utility bills, and a more comfortable home all year round.
