Frequently Asked Questions
- What is a casement operator and why replace it? A casement operator raises and holds the sash, enabling opening and closing. Replacement improves function and prevents drafts.
- How do I know if a track will fit my window? Check the track length, wheel size (often 9/16 inch), and compatibility with your operator model.
- Are bronze finishes purely cosmetic? Bronze finishes provide corrosion resistance and align with certain window styles.
- What maintenance helps extend life? Clean tracks, inspect weather seals, and replace worn components promptly.
- Is tempered glass required for basements? Tempered glass offers safety and helps with insulation and moisture resistance in damp areas.
