I'm looking for information regarding windows for an upcoming project. Specifically, I'm interested in various types of windows, such as double-hung, casement, and sliding styles. It would be great to know about your available options, including materials used, energy efficiency ratings, and any customization features you offer. Additionally, please provide details on your pricing, minimum order quantities, and lead times for delivery. Understanding your bulk order discounts would also be helpful as I plan for potential larger projects in the future. Looking forward to your response with the necessary details!
