The Case for Fiberglass Windows in Baltimore's Climate

Why Baltimore Is Hard On Windows

If you own a house in Baltimore, your windows are dealing with a tough mix of weather year after year. Summer humidity, winter chill, and steady temperature swings all work against tired frames and marginal seals.

This is the point where fiberglass begins to make a real case for itself. Because fiberglass moves less with heat and cold, it tends to keep the sash and frame aligned over time.

On a rowhouse where one corner of a window opening gets sun and another stays shaded, stable framing can make a noticeable difference. The better the frame holds its shape, the less likely you are to end up with drafts, sticky operation, or premature seal problems.

Fiberglass Versus The Usual Baltimore Window Choices

Baltimore homeowners usually end up comparing vinyl, wood, and fiberglass. Each has a place, but they do not perform the same way in this climate.

Vinyl can look attractive up front, but cheaper frames may flex, and darker finishes can show more stress in strong sun. Without that maintenance, moisture and seasonal movement eventually take their toll.

When Fiberglass Is The Right Call
