Is a Double-hung window right for a Glens Falls home?
Both sashes slide vertically and typically tilt inward for cleaning.
Where it fits:
- Traditional and historic home styles
- Rooms facing walkways, porches, or patios (no outward projection)
- Easy cleaning from inside on upper floors
What to weigh:
- More potential air-leakage paths than hinged styles at equal quality
- Half the opening ventilates at any one time
Double-hung windows and Glens Falls's climate
Glens Falls sits in the ENERGY STAR Northern zone (IECC zone 6A (cold, moist), Warren County), where the priority is a low U-factor (≤ 0.22) to keep heat in.
Double-hung sashes seal against weatherstripping as they slide, so they have more potential air-leakage paths than hinged styles. In the Northern zone, prioritize a well-built unit and a low U-factor (≤ 0.22) to offset that.
