- Bay Windows: With three angled windowpanes that extend beyond your home’s exterior walls, bay windows command attention from the curb.

- Casement Windows: These windows swing inward or outward from the side, offering a full sash worth of fresh air.
- Double-Hung Windows: Two operable sashes, instead of the standard single sash, give you even more ventilation.
