What Loudoun County's Climate Demands From Windows

Fiberglass is usually the strongest all-around option for homes that see wide temperature swings. It expands and contracts much less than vinyl, which helps the seal stay consistent and reduces stress on the frame over time.

Wood clad windows bring a different set of strengths. Inside, they offer the look many owners want for older homes, while the exterior cladding protects the frame from weather exposure. For the right house, that is a smart balance.
