Single-hung windows. Budget-friendly & reliable.
Single-hung windows — where only the bottom sash moves while the top stays fixed — are a straightforward, budget-friendly option that still delivers solid energy performance. Because there’s one less moving part than a double-hung window, there’s also one less place for air to leak.
- Lower cost than double-hung
- Fewer moving parts
- Clean, traditional look
