Comparing Window Glass Options for Comfort in Northern Virginia

The glass does more than let in light. It affects heat gain, heat loss, sound, privacy, and how hard your HVAC system has to work.

Northern Virginia weather punishes weak glass. A sunny July afternoon and a January cold front can test the same window in very different ways.

What Different Glass Packages Actually Do

Most homeowners hear terms like Low-E, double-pane, and triple-pane, but the real question is what each option changes inside the house.

Basic clear glass brings in light, but it does not do much to slow heat moving through the window.
